The great gospel doctrine of justification by faith without the works of the law was so very contrary to the notions the Jews had learnt from those that sat in Moses' chair, that it would hardly go down with them; and therefore the apostle insists very largely upon it, and labours much in the confirmation and illustration of it. He had before proved it by reason and argument, now in this chapter he proves it by example, which in some places serves for confirmation as well as illustration. The example he pitches upon is that of Abraham, whom he chooses to mention because the Jews gloried much in their relation to Abraham, put it in the first rank of their external privileges that they were Abraham's seed, and truly they had Abraham for their father. Therefore this instance was likely to be more taking and convincing to the Jews than any other. His argument stands thus: "All that are saved are justified in the same way as Abraham was; but Abraham was justified by faith, and not by works; therefore all that are saved are so justified;" for it would easily be acknowledged that Abraham was the father of the faithful. Now this is an argument, not only à pari—from an equal case, as they say, but à fortiori—from a stronger case. If Abraham, a man so famous for works, so eminent in holiness and obedience, was nevertheless justified by faith only, and not by those works, how much less can any other, especially any of those that spring from him, and come so far short of him in works, set up for a justification by their own works? And it proves likewise, ex abundanti—the more abundantly, as some observe, that we are not justified, no not by those good works which flow from faith, as the matter of our righteousness; for such were Abraham's works, and are we better than he? The whole chapter is taken up with his discourse upon this instance, and there is this in it, which hath a particular reference to the close of the foregoing chapter, where he has asserted that, in the business of justification, Jews and Gentiles stand upon the same level. Now in this chapter, with a great deal of cogency of argument, I. He proves that Abraham was justified not by works, but by faith, ver 1-8. II. He observes when and why he was so justified, ver 9-17. III. He describes and commends that faith of his, ver 17-22. IV. He applies all this to us, ver 22-25. And, if he had now been in the school of Tyrannus, he could not have disputed more argumentatively.
The apostle proves what he had advanced in the last chapter, that the Jews cannot be justified by the works of the written law, nor by any works, unless joined with faith in the Messias, their Redeemer. This he shews by the example of Abraham, who is said to have been justified by believing; 2. and this was before he was circumcised; 3. and long before the law of Moses. Justification was then given without the works of that law. — What advantage shall we say, then, that Abraham hath found, who is our father according to the flesh? This seems the true construction and sense: rather than what did he find according to the flesh, as some expound it. (Witham)
Verses 1-12 To meet the views of the Jews, the apostle first refers to the example of Abraham, in whom the Jews gloried as their most renowned forefather. However exalted in various respects, he had nothing to boast in the presence of God, being saved by grace, through faith, even as others. Without noticing the years which passed before his call, and the failures at times in his obedience, and even in his faith, it was expressly stated in Scripture that "he believed God, and it was counted to him for righteousness," ( Genesis 15:6 ) . From this example it is observed, that if any man could work the full measure required by the law, the reward must be reckoned as a debt, which evidently was not the case even of Abraham, seeing faith was reckoned to him for righteousness. When believers are justified by faith, "their faith being counted for righteousness," their faith does not justify them as a part, small or great, of their righteousness; but as the appointed means of uniting them to Him who has chosen as the name whereby he shall be called, "the Lord our Righteousness." Pardoned people are the only blessed people. It clearly appears from the Scripture, that Abraham was justified several years before his circumcision. It is, therefore, plain that this rite was not necessary in order to justification. It was a sign of the original corruption of human nature. And it was such a sign as was also an outward seal, appointed not only to confirm God's promises to him and to his seed, and their obligation to be the Lord's, but likewise to assure him of his being already a real partaker of the righteousness of faith. Thus Abraham was the spiritual forefather of all believers, who walked after the example of his obedient faith. The seal of the Holy Spirit in our sanctification, making us new creatures, is the inward evidence of the righteousness of faith.
By works, as appeareth in the next verse. A new argument of great weight, taken from the example of Abraham the father of all believers: And this is the proposition: if Abraham be considered in himself by his works, he hath deserved nothing wherein to rejoice with God.
If Abraham were justified by works, or by his own works, he might have glory, and be commended by men, who judge only according to outward appearances; but not with God: that is, he could not be truly justified, so as to deserve a reward in heaven, without faith and the grace of God. (Witham) — Not with God. Whatever glory or applause such works might procure from men, they would be of no value in the sight of God. (Challoner)
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 (v. 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, 1 Cor 4 4; Phil 3 8, 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.
For what saith the Scripture? Abraham believed God, and it was reputed to him unto justice.[1] The Scripture, therefore, teacheth us that he became just by his faith. And as he had this faith by the grace of God, grace was the cause of his justification, and not any works without grace. And when it is said, it was reputed to him, we must not understand an imputation of being just without a true and interior justice: for to be reputed just in the sight of God, who sees the heart, and sanctifies the soul by his interior grace, is the only true justice that can make a man acceptable to God. As not to have our sins imputed in the sight of God, is to have them forgiven, and to be free from our sins. (Witham) — Reputed, &c. By God, who reputeth nothing otherwise than it is. However, we may gather from this word, that when we are justified, our justification proceedeth from God’s free grace and bounty; and not from any efficacy which any act of ours could have of its own nature, abstracting from God’s grace. (Challoner)
II. It is expressly said that Abraham's faith was counted to him for righteousness. What saith the scripture? v. 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, 2 Sam 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.
