4:1-12 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, Ge 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.
3. For what saith the, Scripture? Abraham believed God, and it—his faith.
was counted to him for righteousness—(Ge 15:6). Romish expositors and Arminian Protestants make this to mean that God accepted Abraham's act of believing as a substitute for complete obedience. But this is at variance with the whole spirit and letter of the apostle's teaching. Throughout this whole argument, faith is set in direct opposition to works, in the matter of justification—and even in Ro 4:4, 5. The meaning, therefore, cannot possibly be that the mere act of believing—which is as much a work as any other piece of commanded duty (Joh 6:29; 1Jo 3:23)—was counted to Abraham for all obedience. The meaning plainly is that Abraham believed in the promises which embraced Christ (Ge 12:3; 15:5, &c.), as we believe in Christ Himself; and in both cases, faith is merely the instrument that puts us in possession of the blessing gratuitously bestowed.
