interest that the Saints have in God and the ground of it Their great interest in God is this that whatsoever they ask they receive of him they have such interest that God grants their Prayers whatever they ask And the ground of it is because they keep his Commandements and do those things that are pleasing in his fight Now least they might scruple what Commandements they were that he mean't he tells them in the Verse read of two especially and that is That they believe and that they love one another There be three great Commandements in the Gospel Believing Loving and Repenting Two you have here in the Verse the third in Acts 17.30 The Lord commands every man every where to repent and these two of Loving and Repenting cannot be rightly performed without the first Believing Believing in the Son of God for that love which is without faith is but natural love and that Repentance which is without faith in the Son of God is but legal repentance but that love and that repentance which springs from faith in the Son of God is spiritual love and spiritual repentance The Apostle tells you in 1 Tim. 1.5 The end of the Commandement is charity out of a Pure heart and of a good Conscience and of faith unfeigned If love dont come from faith unfeigned it is not spiritual love In the words read you have First the Commander in the word his Secondly The thing commanded Believing Thirdly The object or person in whom they are to believe or we are to believe set out First by his Relation the Son of God Secondly by his Titles Jesus and Christ The Commander here is God there is none greater than he and therefore his Commands are of greatest authority if in the word of a King there be power how much more in the word of the great and high God and 't is not a verbal Command onely but 't is a written Command that all may take notice of it and may yield obedience unto it The point that I shall commend unto you is this Doct. That believing in the Lord Jesus Christ is a duty under Command In Mark 1.15 saith he Repent ye and believe the Gospel Repentance is commanded and believing the Gospel is commanded and a man cannot believe the Gospel unless he believe in the Son of God I shall not multiply Scriptures to prove it the Text is enough This is his command that we believe in his Son Jesus Christ Now I shall in the prosecution of this point shew you what is imployed in Believing 2. What 's meant by the Name of the Son of God 3. What believing in the name of the Son of God doth also imply And then answer some questions and improve the point For the first what is implyed in believing First Knowledge is implyed in it 't is a blind faith where there is no knowledge the Papists believe as the Church believes and such a faith is a fancy rather than true faith Paul saith I know in whom I have believed and in Joh. 17.3 knowledge there is put for faith so essential is it to faith that it is put for faith it self this is life eternal that they might know thee the onely true God So that in believing there must be knowledge and understanding else it will be a blind believing a blind faith Secondly In believing there is implyed assent of the understanding to the truth that is propounded truth is the object of the understanding As Christ came into the World to save sinners I must assent unto this truth God is in Christ reconciling the world unto himself Such truths and Propositions as these there must be the assent of the understanding unto and Papists will go thus far in the point of faith and make the very formal nature of faith to lye in assent 't is a truth there must be assent but assent is not enough They place it altogether in the understanding and fix it there but the Devils believe and tremble and give assent unto truths they said Christ was the Son of God they gave assent yea the Devils believe and tremble therefore this is not enough though this is required and necessary assent there must be but there must be more than assent But Thirdly There must be Consent which brings in the heart and will and looks at the goodness of the truth or person some good that is in any truth propounded or any person to be believed in Rom. 10.9 10. If thou confess with thy mouth the Lord Jesus and shalt believe in thine heart Not in thine head for with the heart man believeth unto Righteousness with the heart man believes there must be the heart in believing and not the head and understanding onely so that there must be consent of the will and heart unto the thing believed Now this consent must be free and full to have Christ and whole Christ to have Christ at the best and have Christ at the worst whatever may fall out in true believing there is such a free and full consent that it will have Christ whatever it cost Fourthly Lastly in believing there must be affiance a confidence or trust and that you will find express'd in Eph. 1.12 that we should be to the praise of his glory who first trusted in Christ there must be trusting After we know and give assent and consent then we must trust and depend and rely upon Christ So in 2 Tim. 1.12 I know whom I have believed in your margin it is whom I have trusted so that there is a trust a confidence a relyance a recumbency a dependance upon the Lord Jesus Christ where there is a right believing Thus you see what is implyed in believing Secondly What 's meant by the name of Jesus Christ Not the Letters or Syllables as many bow at the name of Jesus that is not the meaning but Name is put for the Thing or put for the person Psal 34.3 Let us exalt his Name together that is God himself let us exalt God himself so thou shalt reverence that dreadful name Jehovah that 's God himself and when you read of Sanctifying the name of God in Scripture that is God himself And so here Rom. 10.13 you will find by Name is meant God himself whosoever shall call upon the Name of the Lord shall be saved that is shall call upon God himself And Acts 4.12 There is none other Name under Heaven given among men whereby we must be saved that is there is no person but Jesus whereby you can be saved And Joh. 3.18 he that believeth on him is not Condemned but he that believeth not is Condemned already because he hath not believed in the Name of the onely begotten Son of God Now what is it to believe in his name or in him First it implyes the receiving into our heads and hearts all things God hath revealed from Heaven concerning him As that he is the Son of God that God gave him for
Spirit in the heart then it 's a sound heart there may be seeming Graces and seeming Comforts but these do not cause soundness Take Brass Tin Cooper let it be Silver'd over by the Art of man this is not sound it is not Currant money so many have parts and they may have seeming graces and seeming comforts and yet not be real not be true such a heart is not sound you read in Scripture of a feigned faith a dead faith you read likewise of feigned love and there are feigned comforts flashy comforts and groundless hopes Now where the heart is sound these are graces comforts wrought by the Word and Spirit hence you read of faith unfeigned 2 Tim. 1.5 and you read of Love the fruit of the Spirit Gal. 5.22 and so peace and joy There 's false peace and false joy but you read of these wrought by the Spirit and love shed abroad in the heart by the Spirit you read of a lively hope of a hope that 's grounded upon the promises 2 Pet. 3.13 Nevertheless we according to his promise look for new Heavens and a new Earth now when graces are real in the heart and comforts are real in the heart and there 's a real truth in them Then the heart is sound And so soundness is opposed to the fancies conceits and dreams of men and their mistakes but their hearts are rotten notwithstanding all their dreams and fancies Fifthly Soundness of heart doth lye in sincerity Let my heart be sound in thy Statutes let it be sincere and upright and so some read the words And the word signifies upright and sincere and so it 's opposed to Hypocrisie O let me not be an Hypocrite let me not be a deceiver a sound heart is a sincere heart where there is Hypocrisie in men and women there 's an unsound heart there 's a rotten heart the Apostle speaks of love without dissimulation Rom. 12.9 So all must be without dissimulation where there is soundness and here both the end and the means and the manner are respected First where the heart is sound there will be sound ends sincere ends and among the rest there be three great ends that a sound heart aims at First the Glory of God Secondly Publick good Thirdly the Spiritual and Eternal good of the Soul First the Glory of God that 's the great end of a sound heart such ends will a sound heart have as Gods Statutes doth propound and hold out now this is one great and high end that God holds out in his word the glorifying of himself Prov. 16.4 God hath made all things for himself for his own glory for his own honour God hath set up his own Glory as his own end and so a sound heart hath that end that God hath propounded So in the 11 Rom. last saith the Apostle there From him and through him and to him are all things to whom be glory for ever Glory is the end 1. Cor. 10.31 Do all to the Glory of God whether you eat or drink or whatever you do that 's the great end 1. Cor. 6. you are not your own you are bought with a price Glorifie God in Soul and Body That 's the great end of a sound heart Secondly the end of a sound heart is publick good Do good to all but especially to the Houshold of Faith not a private and domestick end but do good to all the world if possible but especially to Sion to the Church of God to the people of God saith Hester if I perish I perish Sion is in danger Gods people are in danger I will not stand upon my self and my own safety and upon the Kings Law but Gods glory the welfare and good of Sion lyes at the Stake and I will venture here was a sound heart that had a right end if I perish I perish I will venture my self for God and for his cause and people Thirdly It hath a right end in regard of it self viz. it 's Spiritual and Eternal good A Godly man will have a care of his body but his great care is of his soul and the spiritual and eternal good of his soul Joh. 6.27 Labour not for the meat that perisheth but for that which indureth to everlasting life that meat that perishes concerns the body but there is meat saith Christ which indures to everlasting life and that 's the meat you must look at and that 's the meat a sound heart doth aim at and seek to find out and to feed upon First seek the Kingdom of Heaven and the Righteousness thereof and saith the Apostle in 2 Cor. 4.18 our scope is not to look at the things that are seen but at the things that are not seen things that are eternal and that concern the eternal good of our souls Secondly It is sincere likewise in regard of the means a sound heart will use all the means Psal 119.6 Then shall I not be confounded when I have respect to all thy Commands there must be respect to all Gods Commands to all his Threatnings to all his Promises to all Examples to all Invitations to all Admonitions to all Counsels to the whole will of God a sound heart hath respect to all that God hath revealed to all the means whatsoever they have unsound and rotten hearts who throw off the Law or the Gospel who throw of all Ordinances who throw off the Scriptures but then shall I not be confounded when I have respect to all thy Commands Thirdly So likewise for the manner of using the means many come and hear the word but not with trembling Isa 66.2 not as the word of God 1 Thess 2.13 they receive it not with love 2 Thess 2.13 they mingle it not with faith Heb. 4.2 they hear it not as the word that shall judge them John 12.48 so many pray but not spiritually Ephes 6.18 not feelingly and fervently Rom. 12.11 Jam. 5.16 not believingly Jam. 1.6 so many receive but descern not the Lords Body 1 Cor. 11.29 and many give but not with simplicity Rom. 12.8 and secresie Mat. 6.3 Now a sound heart respects the manner in these and all other duties as much as the duties themselves and is much humbled for failings in the manner of performing duties Sixthly Lastly soundness of heart lyes in this in the hearts putting forth to practice what is revealed to it or received by it when a man hath truth and witholds truth in unrighteousness that man is not sound at the heart but where the heart is sound the soundness of it carries him to practice what is revealed and given in unto it you may see it in David and in Hezekiah 1 K. 15.15 David did that which was right in the eyes of the Lord and turned not aside from any thing that he commanded him all the dayes of his life whatsoever God commanded him that he did his heart was sound in his Statutes And so here in Isa 38. v. 3. Remember now O Lord
careful to please one another according to the word of God their hearts are not sound if Children be not obedient to their Parents Servants serving their Masters not with eye-service but with singleness of heart as unto the Lord their hearts are not sound many will hear the word of God and talk of good things but care not for doing their duties in their places how do they fill up their relations but now if you be sound hearted you will fill up your relations you stand in Seventhly a sound heart can bear sharp afflictions very quietly and meekly a sore Shoulder will bear no burthen a Horse with a gall'd back will winch and kick and fling take a hand that the skin is off and pour vinegar upon it or lay Salt upon it and how terrible is it but if the hand be sound it can bear it if the Shoulder be sound it can bear a burthen if the Horse be sound he can bear the Rider so a sound heart can bear any burthen Moses was a meek man and he bore all the burthen that was upon him But now if the heart be not sound there 's fretting murmuring and repining when the heart is not sound every little thing doth disturb and disquiet it but when its sound it 's like Christ's heart it can bear all burthens whatsoever Eighthly A sound heart is the same towards God in the darkest dispensations that can be as it is to God in the sweetest dispensations that may be when God carries it most strangely and most enemy-like unto the soul that soul is the same towards God still as it was towards God before in the most sweet and pleasing dispensations saith Hab. in his 3. ch Though the Fig-tree should not blossem neither should fruit be in the Vine the Labour of the Olive should fail the fields should yield no meat the flock shall be cut off from the soul and there shall be no heard in the Stall yet will I rejoyce in the Lord I will joy in the God of my Salvation Though there be so great a famine as there is nothing left without or within yet will I rejoyce in God a man uses to rejoyce in God when he hath abundance of the creature but saith Hab. Though none of all these be and there be nothing but famine and I am ready to perish yet will I rejoyce in the Lord his heart was sound and he was the same towards God in one dispensation as in another So Job in the 13. ch 15. v. Though he slay me yet will I trust in him I trusted him when I had all things abounding about me and I will trust in him when all things are taken from me a sound heart is the same at all times Who is among you that feareth the Lord that obeyeth the voice of his Servant which walketh in darkness and hath no light Let him trust in the name of the Lord and stay himself upon his God A sound heart will trust in God in Winter as well as in Summer in a Dark night as well as in a Sun shine day in Phil. 4. I have learned saith Paul in whatever estate I am therewith to be content I can want and I can abound God hath made my heart sound and I can rejoyce in all conditions The Cananitish woman Christ calls her Dog here was a dark dispensation but she calls him Lord Lord the Dogs eat the Crumbs that fall from their Masters Table So that if your hearts be sound in the Statutes and in the things of God your hearts will be the same towards God in adversity as in prosperity in sickness as in health in poverty as in glory and honour Ninthly a sound heart will never turn aside from God or out of his way upon any pretence perswasion or advantage whatsoever but keeps on in Gods way in the Kings road in the way of holiness in the way of truth in the way of righteousness it keeps on in this way and will not be warp'd or turned aside it 's said in 1 K. 15.5 That David did that which was right in the sight of the Lord and turned not aside from any thing that he commanded him all the dayes of his life save onely in the matter of Uriah the Hittie 〈◊〉 through some violent temptations David turned aside once but now here was the integrity and soundness of his heart that he did that which was right in the sight of the Lord and turned not aside from the things that he commanded him all the dayes of his life so that a sound heart will not turn aside 't is not flattery 't is not fear 't is not advantage will make him do it but God is God Truth is Truth as Christ hated iniquity and loved righteousness so doth a sound heart this is the way of God and I will go this way saith a sound heart in the 11. Acts they cleave to God with purpose of heart the Apostle would not take money to give unto Simon Magus the gift of the Holy Ghost and a sound heart it will not be brib'd it will not be couzened it will not turn to the left hand or to the right hand but goes right forward to the end of the way Tenthly A sound heart hath a spiritual confidence and boldness in it and can come unto the Lord in another manner than an unsound and corrupt heart can I say it hath a spiritual boldness and considence in it Heb. 10.19.22 having therefore Brethren boldness to enter into the holyest by the blood of Jesus how comes any to have a spiritual boldness he must have his heart sound if he have any boldness in him if his heart be guilty if his heart be corrupt and rotten there can be no boldness nor confidence but being sound a man hath boldness to enter into the holiest by the blood of Jesus A man that hath interest in the blood of Jesus hath a sound heart and v. 22. Let us draw near with a true heart in full assurance of Faith having our hearts sprinkled from an evil Conscience here 's that makes the heart good and makes the heart bold when the heart is sprinkled with the blood of Christ the Conscience is made sound and good and being thus now let us draw near with a true heart in full assurance such a heart as is sound may come with assurance and confidence unto God and beg of God what he stands in need of this is the nature of a sound heart 11. A sound heart depends upon God alone for all spiritual mercies in 1 Cor. 1. saith the Apostle But of him are ye in Christ Jesus that is of God are we in Christ Jesus God hath drawn you to Christ and stated you in Christ so that of him are ye in Christ Jesus who of God is made unto us Wisdom Righteousness Sanctification and Redemption who of God is made unto us Those that are in Christ Jesus have soundness of heart they have
and wealth and it may be he did not think himself to be one but when he comes to be prov'd to be one he is discovered to be that he was not so in Rev. 2. Thou hast tryed them and found them Lyars they said they were Apostles but they were found by the Church to be no Apostles but Lyars and now they were ashamed so they that said they were Jews and were not but he 's a Jew that is one inwardly and not outwardly only unsound hearted men will be found that which they are not in their own apprehension and in the judgments of others now this will bring shame when men shall be found that which they are not at present and which they were not in the judgment of others Secondly that which brings shame is disappointment when men are disappointed of their expectations Jer. 14. And their Nobles sent their little ones to the waters they came to the pits and found no water they returned with their vessels empty they were ashamed and confounded and covered their heads So that disappointment causes shame as in Isa 20.5 They shall be afraid and ashamed of Ethiopia their expectation and of Egypt their Glory So that when men are disappointed of their expectations then they are ashamed now unfound hearted men they will be disappointed of their expectations they look for Comfort Peace Heaven happiness and Glory but they shall be disappointed the five foolish Virgins they thought to go in to Heaven but they were disappointed of their expectation and so greatly ashamed Thirdly When great evils not look'd for come upon men and women then they are ashamed 2 Sam. 10.5 The men were greatly ashamed there were Ambassadors sent to Hanan and he cuts off half their Beards and half their Garments and here was evil come upon them they look'd not for and they were greatly ashamed so men that are unsound will have evils come upon them that they look'd not for God will bring evil upon them that they look'd not for evil upon their States and evil upon their Names and evils upon their Bodies and Souls and this will make them ashamed Now this shame frequently is in this Life but alwayes at the day of Judgment In this life how are men asham'd what a multitude of men in these dayes are discovered to be unsound hearted full of rotten principles Errors Heresies and sinful complyances and this is their shame what a multitude have divided hearts between God and Mammon what a multitude are discovered to have but seeming grace and no truth of grace in them what a multitude of Hypocrites have we in the world that have pretended fair and high and yet now their Hypocrisie appears they have left the sweet Grapes of Canaan for the stinking Garlick of Egypt what a multitude have we whose hearts are not set to practice what they hear these are all unsound hearted and these are discovered and more and more shall be discovered daily But at last when the Goats shall be set at the left hand and the Sheep at the right hand and Christ shall say go ye Hereticks go ye erroneous persons go you Apostates go you prophane wretches go you Persecutors begon to hell to the Devil and his Angels now they shall be ashamed and confounded for ever So that God he hath his time sooner or later to discover unsound hearted men and women Now that that I shall do here shall be first to shew you who are like to prove unsound and corrupt hearted men and women Secondly to give you some Directions or Arguments to prevent unsoundness of heart shame and confusion First who are like to prove rotten and unsound at the heart First those who do receive truth into impure hearts into divided hearts truth is holy truth is pure and truth never dwells or abides long but in a pure heart t is true truth doth sojourn sometimes in a corrupt heart Lot he sojourns in Sedom a little while Christ lay a while in the manger but he staid not there long and so mens corrupt wills thrust out truth out of the heart it will not let it stay long unless the heart be pure and holy 1 Tim. 3.9 holding the mysterie of the faith in a pure Conscience That is holding the Doctrine of the Gospel and a pure Conscience unless mens hearts and Consciences be pure they will never hold the mysterie they may have some part of the mysterie conveyed unto them which may visit them a little while but their hearts and Consciences cannot hold the fame and then such men and women will prove unfound at the latter end Secondly They are like to prove unsound who do take upon them the profession of Religion and Godliness and do much and go far but not for right ends many have their ends why they will profess Religion why they will have a form of Godliness and why they will do this and that they have their ends why they will get into Church-fellowship some will profess Religion and go far for credit esteem and respect when Religion is in fashion in credit and esteem they will be religious so Scribes and Pharises sought honour of men and so we have those seek honour and credit of men and because of that they will enter upon Religion but they will not be sound some do it for preferment and advantage some again for livelyhood they are poor mean and low in the world and have heavy pressures that way and therefore they will get into a Church that they may be maintained and so live by the sweat of others and think the Church is bound to maintain them and theirs such men as these will prove unsound at the last but have you no better ends to move you then these to be Religious and to look unto Gods Statutes Let my heart be sound in thy Statutes the Glory of God must be your end the good of Souls must be your end the good of your own foul and all other ends must be lay'd by now if men have not such ends as these they will prove rotten at last and will be discovered to their shame Thirdly Those are like to prove unsound at last and be ashamed who have not seriously considered what it may cost them to profess the Gospel to be Christians to enter into Church state and are not resolved to buy the Pearl though it be at the dearest rate they will prove unsound it may cost you something to be Christians so in Luke 14.26 and so forward If any man come to me saith Christ and hate not his Father and Mother and Wife and Children and Brethren and Sisters yea and his own life Mark he cannot be my Disciple and whosoever doth not bear his Cross and come after me cannot be my Disciple for which of you intending to build a Tower sitteth not down first and counteth the cost whether he hath sufficient to finish it least haply after he hath lay'd the Foundation and is
a sound heart he must live upon the word he cannot go a day and not read the word nor meditate on the promises that 's a sickly if not a dead heart which doth so but a sound heart will be feeding upon sound truths relish and digest the same Thirdly A heart that is sound in the Statutes of God doth look at the Statutes of God for themselves for their own sakes many you know do look at learning they will learn at the Grammar School and they will profit at the University but they do not look at learning for learning but for credit and to get a living and be some body in the world this is base So many look at the Statutes of God but not for the Statutes sake but that they may be encreased in knowledge and be sav'd at last but a sound heart looks at Gods Statutes for themselves in Psal 119. I have chosen the way of truth and v. 31. I have stuck unto thy Testimonies O God and he saith he doth prize them above thousands of Gold and Silver and above great spoils and they are his Songs in the house of his Pilgrimage why he look'd at them for themselves O! Gods Statutes they are such precious truths that let me have them though I have nothing of the world Some you know look at a Diamond because of the shining and sparkling of it self not because they shall Merchandize with it and make themselves rich So that 's sound when a man looks at Gods divine truths they are full of Glory they are beams of Gods wisdom there 's excellency in them this argues soundness of heart but many look at the truths of God as suitable to their humours they have such a lust and this will agree with their lust and so they will pick here and there which argues unsoundness as a sickly Stomach will pick a bit here and there but a sound heart looks at Gods Statutes for themselves and that excellency and worth is in them Fourthly A sound heart labours to know the will of God and seeing it to be the will of God sticks not at hard things at reproachful things let the things be never so hard never so reproachful it sticks not at it well is this the will of God saith the sound heart I will embrace it saith Christ It is written in the volume of thy Book that I should do thy will and loe I come but consider what this will is thou must be a servant thou must be persecuted into Egypt thy life must be sought among the little Children thou must be accounted an enemy to Caesar a breaker of the Sabbath thou must be reproach'd and hanged upon a Cross and be Crucifyed between Thieves and Murderers what wilt thou go now I it 's written in the volume of thy Book that I must do thy will and loe I come he sticks not at any or all of these things saith God to Abraham Abraham go and Sacrifice your onely Son Isaac unto me O Lord might he say this is a hard business what murder my Son what will my Wife say it will be her death what will the Nations say here was a bloody man to murther his Son and so I may be put to death for it I but it was the will of God and so he stuck not at it Fifthly a sound heart may be known by this that it is willing and ready to part with any thing for the Lords sake saith a sound heart what will this do me good if I lose my integrity if I lose my sincerity if I lose now my fitness to do God service by defiling my self what shall I get you know the young man comes to Christ and saith Good Master what shall I do to inherit eternal life saith he keep the Commandements Why all these things have I kept from my youth up saith Christ go and sell all that thou hast and give to the poor and come and follow me and thou shalt have treasure in heaven One would think here had been promise enough for him and treasure enough for him but he had rotten principles in him he had the world in him his heart was for the world and the creature and nothing of it for God Simon Magus went further than this man did he was a Professor and got into a Church Relation he brings out his bags of Gold and Silver and would give them to the Apostles that he might have that power they had to give the Holy Ghost but saith Peter thy heart is not right therefore pray if it be possible that the thoughts of thy heart may be forgiven thee But now a gracious heart indeed will part with all saith Paul I account all less and dung Phil. 3. All my priviledges all my learning all that ever I have I account it loss and dung for the excellency of the knowledge of Jesus Christ and say the Disciples Master we have left all to follow thee and you know Galeatius left all for Christs sake and comes to Geneva that he might enjoy the Gospel And the Martyrs they left their lives what dearer than a mans life yet they were ready to let go their lives rather then to let go their foundness Sixthly A sound heart is that which doth fill up all its relations what relation soever it stands in towards God towards man towards the publick towards its family it will fill up its relations Acts 24.16 saith Paul herein do I exercise my self to have alwayes a Conscience void of offence towards God and towards man saith Paul I stand in relation to God and I do exercise my self in this that I may have my Conscience cleer and free I will do all my duties towards God that he calls for otherwise I shall not have a Conscience free and towards men in every relation I stand in towards men I am careful to fill up those relations So that a sound heart is wonderful cautious in doing any thing in any relation that may not fill up its relation as Joshua Ch. 24.15 Let others do what they will I and my house will serve the Lord Others will serve their lusts and serve the times and serve men and serve Devils but I and my house will serve the Lord I am Master of this Family and I will see my Wife and Children and Servants and all under my roof to serve the Lord so saith God of Abraham I know that he will instruct and teach his Family Gen. 18.19 And so David in Psal 101. I will walk in my house with a perfect heart I will not suffer a wicked person to stay within my Family No Drunkard no Swearer no Sabbath-Breaker no prophane wretch shall stay in my Family So that a sound heart fills up its relations some make no Conscience at all of their places they are unfaithful they can hardly be trusted in any place they are in but they have no sound hearts Husbands to Wives Wives to Husbands if not
the very heart and mind of Christ now saith he who of God is made unto us Wisdom Righteousness Sanctification and Redemption That soul depends upon God for Wisdome from Christ for Sanctification from Christ for Righteousness from Christ for Redemption from Christ it doth not depend upon its own Acts it s own Experiences it s own Graces it s own Comforts it doth not depend upon the Law it doth not depend upon the Gospel but upon God through Christ so that a sound heart sees through all unto God who is the root and fountain and fetches all from thence it takes up all from God from God through a Covenant of Grace from God through Christ so that as it is in Isa 45.24 Verily shall one say in the Lord have I righteousness and strength I have it not from an Ordinance I have it not in my self but from God through Christ from God through an Ordinance saith David my soul wait thou onely upon the Lord for from him cometh thine expectation 12. Lastly for discovery of a sound heart a sound heart is that conforms to Gods word not to the world in Rom. 12. beginning be not conformed to this world but be ye transformed by the renewing of your minds that ye may prove what is that good that acceptable and perfect will of God When a man is transformed by the renewing of his mind he is a sound minded a sound hearted man but till then he is a corrupt hearted man Now if you be sound hearted you will not conform to the world but to the word which is the will of God revealed That good that acceptable that perfect will of God you will conform to saith Paul in 6. Gal. 14. I am Crucified to the world he now conforms to the good and acceptable will of God for God would have us to look at Christ Crucified and to dye to sin through the death of Christ and Paul looks at Christ Crucified and is dead to the world and the world was dead to him he would not conform to the world a sound heart conforms not to the world worldly worship worldly customes worldly fashions worldly manners but conforms to the word therefore look to it for few sound hearted there are so many conform to the world and so few to the word but a sound heart will conform to sound Doctrine the sound word and not to the world that lyes in wickedness and thus you see several discoveries of a sound heart Use 4.
