Here the apostle proves that Abraham was justified not by works, but by faith. Those that of all men contended most vigorously for a share in righteousness by the privileges they enjoyed, and the works they performed, were the Jews, and therefore he appeals to the case of Abraham their father, and puts his own name to the relation, being a Hebrew of the Hebrews: Abraham our father. Now surely his prerogative must needs be as great as theirs who claim it as his seed according to the flesh. Now what has he found? All the world is seeking; but, while the most are wearying themselves for very vanity, none can be truly reckoned to have found, but those who are justified before God; and thus Abraham, like a wise merchant, seeking goodly pearls, found this one pearl of great price. What has he found, kata sarka - as pertaining to the flesh, that is, by circumcision and his external privileges and performances? These the apostle calls flesh, Phi 3:3. Now what did he get by these? Was he justified by them? Was it the merit of his works that recommended him to God's acceptance? No, by no means, which he proves by several arguments. I. If he had been justified by works, room would have been left for boasting, which must for ever be excluded. If so, he hath whereof to glory (Rom 4:2), which is not to be allowed. "But," might the Jews say, "was not his name made great (Gen 12:2), and then might not he glory?" Yes, but not before God; he might deserve well of men, but he could never merit of God. Paul himself had whereof to glory before men, and we have him sometimes glorying in it, yet with humility; but nothing to glory in before God, Co1 4:4; Phi 3:8, Phi 3:9. So Abraham. Observe, He takes it for granted that man must not pretend to glory in any thing before God; no, not Abraham, as great and as good a man as he was; and therefore he fetches an argument from it: it would be absurd for him that glorieth to glory in any but the Lord. II. It is expressly said that Abraham's faith was counted to him for righteousness. What saith the scripture? Rom 4:3. In all controversies in religion this must be our question, What saith the scripture? It is not what this great man, and the other good man, say, but What saith the scripture? Ask counsel at this Abel, and so end the matter, Sa2 2:18. To the law, and to the testimony (Isa 8:20), thither is the last appeal. Now the scripture saith that Abraham believed, and this was counted to him for righteousness (Gen 15:6); therefore he had not whereof to glory before God, it being purely of free grace that it was so imputed, and having not in itself any of the formal nature of a righteousness, further than as God himself was graciously pleased so to count it to him. It is mentioned in Genesis, upon occasion of a very signal and remarkable act of faith concerning the promised seed, and is the more observable in that it followed upon a grievous conflict he had had with unbelief; his faith was now a victorious faith, newly returned from the battle. It is not the perfect faith that is required to justification (there may be acceptable faith where there are remainders of unbelief), but the prevailing faith, the faith that has the upper hand of unbelief. III. If he had been justified by faith, the reward would have been of debt, and not of grace, which is not to be imagined. This is his argument (Rom 4:4, Rom 4:5): Abraham's reward was God himself; so he had told him but just before (Gen 15:1), I am thy exceeding great reward. Now, if Abraham had merited this by the perfection of his obedience, it had not been an act of grace in God, but Abraham might have demanded it with as much confidence as ever any labourer in the vineyard demanded the penny he had earned. But this cannot be; it is impossible for man, much more guilty man, to make God a debtor to him, Rom 11:35. No, God will have free grace to have all the glory, grace for grace's sake, Joh 1:16. And therefore to him that worketh not - that can pretend to no such merit, nor show any worth or value in his work, which may answer such a reward, but disclaiming any such pretension casts himself wholly upon the free grace of God in Christ, by a lively, active, obedient faith - to such a one faith is counted for righteousness, is accepted of God as the qualification required in all those that shall be pardoned and saved. Him that justifieth the ungodly, that is, him that was before ungodly. His former ungodliness was no bar to his justification upon his believing: ton asebē - that ungodly one, that is, Abraham, who, before his conversion, it should seem, was carried down the stream of the Chaldean idolatry, Jos 24:2. No room therefore is left for despair; though God clears not the impenitent guilty, yet through Christ he justifies the ungodly. IV. He further illustrates this by a passage out of the Psalms, where David speaks of the remission of sins, the prime branch of justification, as constituting the happiness and blessedness of a man, pronouncing blessed, not the man who has no sin, or none which deserved death (for then, while man is so sinful, and God so righteous, where would be the blessed man?) but the man to whom the Lord imputeth not sin, who though he cannot plead, Not guilty, pleads the act of indemnity, and his plea is allowed. It is quoted from Psa 32:1, Psa 32:2, where observe, 1. The nature of forgiveness. It is the remission of a debt or a crime; it is the covering of sin, as a filthy thing, as the nakedness and shame of the soul. God is said to cast sin behind his back, to hide his face from it, which, and the like expressions, imply that the ground of our blessedness is not our innocency, or our not having sinned (a thing is, and is filthy, though covered; justification does not make the sin not to have been, or not to have been sin), but God's not laying it to our charge, as it follows here: it is God's not imputing sin (Rom 4:8), which makes it wholly a gracious act of God, not dealing with us in strict justice as we have deserved, not entering into judgment, not marking iniquities, all which being purely acts of grace, the acceptance and the reward cannot be expected as debts; and therefore Paul infers (Rom 4:6) that it is the imputing of righteousness without works. 2. The blessedness of it: Blessed are they. When it is said, Blessed are the undefiled in the way, blessed is the man that walketh not in the counsel of the wicked, etc., the design is to show the characters of those that are blessed; but when it is said, Blessed are those whose iniquities are forgiven, the design is to show what that blessedness is, and what the ground and foundation of it. Pardoned people are the only blessed people. The sentiments of the world are, Those are happy that have a clear estate, and are out of debt to man; but the sentence of the word is, Those are happy that have their debts to God discharged. O how much therefore is it our interest to make it sure to ourselves that our sins are pardoned! For this is the foundation of all other benefits. So and so I will do for them; for I will be merciful, Heb 8:12.

St. Paul observes in this paragraph when and why Abraham was thus justified; for he has several things to remark upon that. It was before he was circumcised, and before the giving of the law; and there was a reason for both. I. It was before he was circumcised, Rom 4:10. His faith was counted to him for righteousness while he was in uncircumcision. It was imputed, Gen 15:6, and he was not circumcised till ch. 17. Abraham is expressly said to be justified by faith fourteen years, some say twenty-five years, before he was circumcised. Now this the apostle takes notice of in answer to the question (Rom 4:9), Cometh this blessedness then on the circumcision only, or on the uncircumcision also? Abraham was pardoned and accepted in uncircumcision, a circumstance which, as it might silence the fears of the poor uncircumcised Gentiles, so it might lower the pride and conceitedness of the Jews, who gloried in their circumcision, as if they had the monopoly of all happiness. Here are two reasons why Abraham was justified by faith in uncircumcision: - 1. That circumcision might be a seal of the righteousness of faith, Rom 4:11. The tenour of the covenants must first be settled before the seal can be annexed. Sealing supposes a previous bargain, which is confirmed and ratified by that ceremony. After Abraham's justification by faith had continued several years only a grant by parole, for the confirmation of Abraham's faith God was pleased to appoint a sealing ordinance, and Abraham received it; though it was a bloody ordinance, yet he submitted to it, and even received it as a special favour, the sign of circumcision, etc. Now we may hence observe, (1.) The nature of sacraments in general: they are signs and seals - signs to represent and instruct, seals to ratify and confirm. They are signs of absolute grace and favour; they are seals of the conditional promises; nay, they are mutual seals: God does in the sacraments seal to us to be to us a God, and we do therein seal to him to be to him a people. (2.) The nature of circumcision in particular: it was the initiating sacrament of the Old Testament; and it is here said to be, [1.] A sign - a sign of that original corruption which we are all born with, and which is cut off by spiritual circumcision, - a commemorating sign of God's covenant with Abraham, - a distinguishing sign between Jews and Gentiles, - a sign of admission into the visible church, - a sign prefiguring baptism, which comes in the room of circumcision, now under the gospel, when (the blood of Christ being shed) all bloody ordinances are abolished; it was an outward and sensible sign of an inward and spiritual grace signified thereby. [2.] A seal of the righteousness of the faith. In general, it was a seal of the covenant of grace, particularly of justification by faith - the covenant of grace, called the righteousness which is of faith (Rom 10:6), and it refers to an Old Testament promise, Deu 30:12. Now if infants were then capable of receiving a seal of the covenant of grace, which proves that they then were within the verge of that covenant, how they come to be now cast out of the covenant and incapable of the seal, and by what severe sentence they were thus rejected and incapacitated, those are concerned to make out that not only reject, but nullify and reproach, the baptism of the seed of believers. 2. That he might be the father of all those that believe. Not but that there were those that were justified by faith before Abraham; but of Abraham first it is particularly observed, and in him commenced a much clearer and fuller dispensation of the covenant of grace than any that had been before extant; and there he is called the father of all that believe, because he was so eminent a believer, and so eminently justified by faith, as Jabal was the father of shepherds and Jubal of musicians, Gen 4:20, Gen 4:21. The father of all those that believe; that is, a standing pattern of faith, as parents are examples to their children; and a standing precedent of justification by faith, as the liberties, privileges, honours, and estates, of the fathers descend to their children. Abraham was the father of believers, because to him particularly the magna charta was renewed. (1.) The father of believing Gentiles, though they be not circumcised. Zaccheus, a publican, if he believe, is reckoned a son of Abraham, Luk 19:9. Abraham being himself uncircumcised when he was justified by faith, uncircumcision can never be a bar. Thus were the doubts and fears of the poor Gentiles anticipated and no room left to question but that righteousness might be imputed to them also, Col 3:11; Gal 5:6. (2.) The father of believing Jews, not merely as circumcised, and of the seed of Abraham according to the flesh, but because believers, because they are not of the circumcision only (that is, are not only circumcised), but walk in the steps of that faith - have not only the sign, but the thing signified - not only are of Abraham's family, but follow the example of Abraham's faith. See here who are the genuine children and lawful successors of those that were the church's fathers: not those that sit in their chairs, and bear their names, but those that tread in their steps; this is the line of succession, which holds, notwithstanding interruptions. It seems, then, those were most loud and forward to call Abraham father that had least title to the honours and privileges of his children. Thus those have most reason to call Christ Father, not that bear his name in being Christians in profession, but that tread in his steps. II. It was before the giving of the law, Rom 4:13-16. The former observation is levelled against those that confined justification to the circumcision, this against those that expected it by the law; now the promise was made to Abraham long before the law. Compare Gal 3:17, Gal 3:18. Now observe, 1. What that promise was - that he should be the heir of the world, that is, of the land of Canaan, the choicest spot of ground in the world, - or the father of many nations of the world, who sprang from him, besides the Israelites, - or the heir of the comforts of the life which now is. The meek are said to inherit the earth, and the world is theirs. Though Abraham had so little of the world in possession, yet he was heir of it all. Or, rather, it points at Christ, the seed here mentioned; compare Gal 3:16, To thy seed, which is Christ. Now Christ is the heir of the world, the ends of the earth are his possession, and it is in him that Abraham was so. And it refers to that promise (Gen 12:3), In thee shall all the families of the earth be blessed. 2. How it was made to him: Not through the law, but through the righteousness of faith. Not through the law, for that was not yet given: but it was upon that believing which was counted to him for righteousness; it was upon his trusting God, in his leaving his own country when God commanded him, Heb 11:8. Now, being by faith, it could not be by the law, which he proves by the opposition there is between them (Rom 4:14, Rom 4:15): If those who are of the law be heirs; that is, those, and those only, and they by virtue of the law (the Jews did, and still do, boast that they are the rightful heirs of the world, because to them the law was given), then faith is made void; for, if it were requisite to an interest in the promise that there should be a perfect performance of the whole law, then the promise can never take its effect, nor is it to any purpose for us to depend upon it, since the way to life by perfect obedience to the law, and spotless sinless innocency, is wholly blocked up, and the law in itself opens no other way. This he proves, Rom 4:15. The law worketh wrath - wrath in us to God; it irritates and provokes that carnal mind which is enmity to God, as the damming up of a stream makes it swell - wrath in God against us. It works this, that is, it discovers it, or our breach of the law works it. Now it is certain that we can never expect the inheritance by a law that worketh wrath. How the law works wrath he shows very concisely in the latter part of the verse: Where no law is there is no transgression, an acknowledged maxim, which implies, Where there is a law there is transgression and that transgression is provoking, and so the law worketh wrath. 3. Why the promise was made to him by faith; for three reasons, Rom 4:16. (1.) That it might be by grace, that grace might have the honour of it; by grace, and not by the law; by grace, and not of debt, nor of merit; that Grace, grace, might be cried to every stone, especially to the top-stone, in this building. Faith hath particular reference to grace granting, as grace hath reference to faith receiving. By grace, and therefore through faith, Eph 2:8. For God will have every crown thrown at the feet of grace, free grace, and every song in heaven sung to that tune, Not unto us, O Lord, not unto us, but unto thy name be the praise. (2.) That the promise might be sure. The first covenant, being a covenant of works, was not sure: but, through man's failure, the benefits designed by it were cut off; and therefore, the more effectually to ascertain and ensure the conveyance of the new covenant, there is another way found out, not by works (were it so, the promise would not be sure, because of the continual frailty and infirmity of the flesh), but by faith, which receives all from Christ, and acts in a continual dependence upon him, as the great trustee of our salvation, and in whose keeping it is safe. The covenant is therefore sure, because it is so well ordered in all things, Sa2 23:5. (3.) That it might be sure to all the seed. If it had been by the law, it had been limited to the Jews, to whom pertained the glory, and the covenants, and the giving of the law (Rom 9:4); but therefore it was by faith that Gentiles as well as Jews might become interested in it, the spiritual as well as the natural seed of faithful Abraham. God would contrive the promise in such a way as might make it most extensive, to comprehend all true believers, that circumcision and uncircumcision might break no squares; and for this (Rom 4:17) he refers us to Gen 17:5, where the reason of the change of his name from Abram - a high father, to Abraham - the high father of a multitude, is thus rendered: For a father of many nations have I made thee; that is, all believers, both before and since the coming of Christ in the flesh, should take Abraham for their pattern, and call him father. The Jews say Abraham was the father of all proselytes to the Jewish religion. Behold, he is the father of all the world, which are gathered under the wings of the Divine Majesty. - Maimonides.
