Contained in Scripture, and held forth briefly in the foresaid Confession of Faith and Catechisms.
The chief general use of Christian doctrine is, to convince a man of sin, and of righteousness, and of judgment, John 16.8 partly by the law or covenant of works, that he may be humbled and become penitent; and partly by the gospel or covenant of grace, that he may become an unfeigned believer in Jesus Christ, and be strengthened in his faith upon solid grounds and warrants, and give evidence of the truth of his faith by good fruits, and so be saved.
The sum of the covenant of works, or of the law, is this:
"If thou do all that is commanded, and not fail in any point, thou shalt be saved: but if thou fail, thou shalt die." Ro. 10:5, Gal 3:10,12.
The sum of the gospel, or covenant of grace and reconciliation, is this:
"If thou flee from deserved wrath to the true Redeemer Jesus Christ, (who is able to save to the uttermost all that come to God through him,) thou shalt not perish, but have eternal life." Rom 10:8,9,11.
For convincing a man of sin, of righteousness, and of judgment by the law, or covenant of works, let those scriptures, among many more, be made use of.
"The heart is deceitful above all things, and desperately wicked: who can know it? I the Lord search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings."
Here the Lord teaches two things:
1a) That the fountain of all our wickedness, and actual sinning against God, is in the heart, which comprehends the mind, will, affections, and all the powers of the soul, as they are corrupted and defiled with original sin; the mind being not only ignorant and incapable of saving truth, but also full of error and enmity against God; and the will and affections being obstinately disobedient to all God's directions, and bend toward that only which is evil: "The heart" (saith he) "is deceitful above all things, and desperately wicked;" yea and unsearchably wicked, so that no man can know it; and Gen 6.5 "Every imagination of the thoughts "of man's heart is only evil continually," saith the Lord, whose testimony we must trust in this and all other matters; and experience also may teach us, that, till God make us deny ourselves, we never look to God in anything, but fleshly self interest alone does rule us, and move all the wheels of our actions.
1b) That the Lord brings our original sin, or wicked inclination, with all its actual fruits, to reckoning before his judgment seat; "For he searches the heart, and tries the reins, to give every man according to his ways, and according to the fruit of his doings."
Hence let every man reason thus:
"What God and my guilty conscience bears witness of, I am convinced that it is true: But God and my guilty conscience bears witness that my heart is deceitful above all things and desperately wicked; and that all the imaginations of my heart, are only evil continually:" "Therefore I am convinced that this true."
Thus a man may be convinced of sin by the law.
"As many as are of the works of the law are under the curse: for it is written, Cursed is every one that continues not in all things which are written in the book of the law to do them."
Here the apostle teaches us three things.
2a) That, by reason of our natural sinfulness, the impossibility of any man's being justified by the works of the law is so certain, that whoever does seek justification by works of the law, are liable to the curse of God for breaking of the law; "For as many as are of the works of the law are under the curse," he says.
2b) That, to the perfect fulfilling of the law, the keeping of one or two of the precepts, or doing of some, or of all duties (if it were possible) for a time is not sufficient; for the law requires, that "a man continue in all things which are written in the book of the law to do them."
2c) That, because no man can come up to this perfection, every man by nature is under the curse; for the law says, "Cursed is every one that continues not in all things which are written in the book of the law to do them."
Now, to be under the curse, comprehends all the displeasure of God, with the danger of the breaking forth more and more of his wrath upon soul and body, both in this life, and after death perpetually, if grace does not prevent its execution.
Hence let every man reason thus:
"Whoever, according to the covenant of works, is liable to the curse of God for breaking the law, times and ways out of number, cannot be justified, or find righteousness by the works of the law:" But I, (may every man say,) according to the covenant of works, am liable to the curse of God, for breaking the law times and ways without number: Therefore I cannot be justified, or have righteousness by the works of the law."
Thus may a man be convinced of righteousness, that it is not to be had by his own works, or by the law.
"7 The Lord Jesus shall be revealed from heaven with his mighty angels, 8 In flaming fire, taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ: 9 Who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power; 10 When he shall come to be glorified in his saints, and to be admired in all them that believe." 2 Th. 2:7-10
Wherein we are taught, that our Lord Jesus, who now offers to be Mediator for them who believe in him, shall, at the last day, come armed with flaming fire, to judge, condemn, and destroy all them who have not believed God, have not received the offer of grace made in the gospel, not obeyed its doctrine; but remain in their natural state, under the law or covenant of works.
Hence let every man reason thus:
"What the righteous Judge has forewarned me shall be done at the last day, I am sure is a just judgment: "But the righteous Judge has forewarned me, that if I do not believe God in time, and obey not the doctrine of the gospel, I shall be secluded from his presence and his glory at the last day, and be tormented in soul and body for ever:" "Therefore I am convinced that this is a just judgment:" "And I have reason to thank God heartily, who has forewarned me to flee from the wrath which is to come."
Thus every man may be, by the law or covenant of works, convinced of judgment, if he shall continue under the covenant of works, or shall not obey the gospel of our Lord Jesus.
As for convincing a man of sin, and righteousness, and judgment, by the gospel, or covenant of grace, he must understand three things:
4a) That not believing in Jesus Christ, or refusing of the covenant of grace offered in him, is a greater and more dangerous sin than all other sins against the law; because the hearers of the gospel, not believing in Christ, do reject God's mercy in Christ, the only way of freedom from sin and wrath, and will not yield to be reconciled to God.
4b) Next, he must understand, that perfect remission of sin, and true righteousness, is to be had only by faith in Jesus; but God requires no other conditions but faith; and testifies from heaven, that he is well pleased to justify sinners upon this condition.
4c) He must understand, that upon righteousness received by faith, judgment shall follow, on the one hand, to the destroying of the works of the devil in the believer, and to the perfecting of the work of sanctification in him, with power: and that, upon refusing to take righteousness by faith in Jesus Christ, judgment shall follow, on the other hand, to the condemnation of the unbeliever, and destroying of him with Satan and his servants for ever.
For this end, let these passages of scripture, among many others, serve to make the greatness of the sin of not believing in Christ appear; or, to make the greatness of the sin of refusing of the covenant of grace offered to us, in the offering of Christ to us appear, let the fair offer of grace be looked upon as it is made, Isa. 55.3 "Incline your ear, and come to me, (says the Lord:) hear, and your soul shall live; and I will make an everlasting covenant with you, even the sure mercies of David." That is, If you will believe me, and be reconciled to me, I will, by covenant, give to you Christ, and all saving graces in him: repeated Acts 13.34.
Again, consider, that this general offer in substance is equivalent to a special offer made to every one in particular; as appears by the apostle's making use of it, Acts 16.31. "Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house." The reason of which offer is given, John 3.16. "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." Seeing then this great salvation is offered in the Lord Jesus, whoever believes not in him, but looks for happiness some other way, what does he else but observe lying vanities, and forsake his own mercy, which he might have had in Christ? Jonah 2.8,9. What does he else but blaspheme God in his heart? as it is said, 1 John 5.10,11. "He that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son. And this is the record, that God has given to us eternal life; and this life is in his Son." And that no sin against the law is like to this sin, Christ testifies, John 15.22. "If I had not come and spoken to them, they had not sin; but now they have no cloak for their sin." This may convince a man of the greatness of this sin of not believing in Christ.
For convincing a man of righteousness to be had only by faith in Jesus Christ, consider how, Rom. 10.3,4
It is said, that the Jews, "being ignorant of God's righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God," (and so they perished.) "For Christ is the end of the law for righteousness to every one that believeth." And Acts 13.39. "By him all that believe are justified from all things, from which ye could not be justified by the law of Moses." And 1 John 1.7 "The blood of Jesus Christ his Son cleanseth us from all sin."
For convincing a man of judgment, if a man embrace this righteousness, consider 1 John 3.8. "For this purpose the Son of God was manifested, that he might destroy the works of the devil." And Heb 9.14. "How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God."
But if a man embrace not this righteousness, his doom is pronounced, John 3.18,19. "He that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. And this is the condemnation, that light is come into the world, and men loved darkness rather than light."
Hence let the penitent, desiring to believe, reason thus:
"What does suffice to convince all the elect in the world of the greatness of the sin of not believing in Christ, or refusing to flee to him for relief from sins done against the law, and from wrath due to it; and what suffices to convince them that righteousness and eternal life is to be had by faith in Jesus Christ, or by consenting to the covenant of grace in him; and what suffices to convince them of judgment to be exercised by Christ, for destroying the works of the devil in a man, and sanctifying and saving all that believe in him, may suffice to convince me also:" "But what the Spirit has said, in these or other like scriptures, suffices to convince the elect world of the foresaid sin, and righteousness, and judgment:" "Therefore what the Spirit has said, in these and other like scriptures, serves to convince me of it also."
Whereupon let the penitent desiring to believe take with him words, and say heartily to the Lord, Seeing you say, "Seek ye my face;" my soul answers to you, "Thy face, Lord, will I seek." I have harkened to the offer of an everlasting covenant of all saving mercies to be had in Christ, and I do heartily embrace your offer. Lord, let it be a bargain; "Lord, I believe; help my unbelief:" Behold, I give myself to you, to serve you in all things for ever; and I hope "your right hand shall save me:" the Lord will perfect that which concerns me: your mercy, O Lord, endures for ever; forsake not "the works of thine own hands."
Thus may a man be made an unfeigned believer in Christ.
For strengthening the man's faith who has agreed to the covenant of grace.
Because many true believers are weak, and do much doubt if ever they shall be sure of the soundness of their own faith and effectual calling, or made certain of their justification and salvation, when they see that many who profess faith, are found to deceive themselves; let us see how every believer may be made strong in the faith, and sure of his own election and salvation upon solid grounds, by sure warrants, and true evidences of faith. To this end, among other scriptures, take these following.
2 Peter 1.10 "Therefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things ye shall never fall."
In which words, the apostle teaches us these four things, for help and direction how to be made strong in the faith.
1a) That such as believe in Christ Jesus, and are fled to him for relief from sin and wrath, albeit they be weak in the faith, yet they are indeed children of the same Father with the apostles; for so he accounts of them, while he calls them brethren.
1b) That albeit we are not sure, for the time, of our effectual calling and election, yet we may be made sure of both, if we use diligence; for this he presupposes, saying, "Give diligence; to make your calling and election sure."
1c) That we must not be discouraged, when we see many seeming believers prove rotten branches, and make defection; but we must the rather take the better heed to ourselves: "Wherefore the rather, brethren, (said he,) give all diligence."
1d) That the way to be sure both of our effectual calling and election, is to make sure work of our faith, by laying the grounds of it solidly, and bringing forth the fruits of our faith in new obedience constantly: "For if ye do these things, (said he,) ye shall never fall;" understanding by "these things" what he had said of sound faith, Verses 1,2,3,4 and what he had said of the bringing out of the fruits of faith, Verses 5.6,7,8,9.
"1 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. 2 For the law of the Spirit of life in Christ Jesus has made me free from the law of sin and death. 3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh; 4 That the righteousness of the law might be fulfilled in us, who walk not after flesh, but after the Spirit."
Wherein the apostle teaches us these four things, for laying of the ground of faith solidly:
2a) That every one is a true believer, who, in the sense of his sin, and fear of God's wrath, does flee for full relief from both to Jesus Christ alone, as the only Mediator and all-sufficient Redeemer of men; and, being fled to Christ, does strive against his own flesh, or corrupt inclination of nature, and studies to follow the rule of God's Spirit, set down in his word: for the man, whom the apostle does here bless as a true believer, is a man in Christ Jesus, "who doth not walk after the flesh, but after the Spirit."
2b) That all such persons as are fled to Christ, and do strive against sin, however they may be possibly exercised under the sense of wrath, and fear of condemnation, yet they are in no danger; for "there is no condemnation (said he) to them that are in Christ Jesus, who walk not after the flesh, but after the Spirit."
2c) That albeit the apostle himself, (brought in here for example's cause,) and all other true believers in Christ, be by nature under the law of sin and death, or under the covenant of works, (called the law of sin and death, because it binds sin and death upon us, till Christ set us free;) yet the law of the Spirit of life in Christ Jesus, or the covenant of grace, (so called, because it does enable and quicken a man to a spiritual life through Christ,) does set the apostle, and all true believers, free from the covenant of works, or the law of sin and death: so that every man may say with him, "The law of the Spirit of life," or the covenant of grace, "has made me free from the law of sin and death," or the covenant of works.
2d) That the fountain and first ground, from whence our freedom from the curse of the law does flow, is the covenant of redemption, passed between God and God the Son as incarnate, wherein Christ takes the curse of the law upon him for sin, that the believer, who could not otherwise be delivered from the covenant of works, may be delivered from it.
2d1) That it was utterly impossible for the law, or the covenant of works, to bring righteousness and life to a sinner, because it was weak.
2d2) That this weakness and inability of the law, or covenant of works, is not the fault of the law, but the fault of sinful flesh, which is neither able to pay the penalty of sin, not to give perfect obedience to the law, (presupposing past sins were forgiven:) "The law was weak (said he,) through the flesh"
2d3) That the righteousness and salvation of sinners, which was impossible to be brought about by the law, is brought to pass by sending God's own Son, Jesus Christ, in the flesh, in whose flesh sin is condemned and punished, for making satisfaction in the behalf of the elect, that they might be set free.
2d4) That by his means the law loses nothing, because the righteousness of the law is best fulfilled this way, first, by Christ's giving perfect active obedience in our name to it in all things; next, by his paying in our name the penalty due to our sins in his death: and, lastly, by his working of sanctification in us, who are true believers, who strive to give new obedience to the law, and "walk not after the flesh, but after the Spirit."
