9 Is this blessedness, then, pronounced only on the circumcised, or also on the uncircumcised? We say, "Faith was reckoned to Abraham as righteousness." 10 How then was it reckoned to him? Was it before or after he had been circumcised? It was not after, but before he was circumcised. 11 He received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. The purpose was to make him the ancestor of all who believe without being circumcised and who thus have righteousness reckoned to them, 12 and likewise the ancestor of the circumcised who are not only circumcised but who also follow the example of the faith that our ancestor Abraham had before he was circumcised.
13 For the promise that he would inherit the world did not come to Abraham or to his descendants through the law but through the righteousness of faith. 14 If it is the adherents of the law who are to be the heirs, faith is null and the promise is void. 15 For the law brings wrath; but where there is no law, neither is there violation. 16 For this reason it depends on faith, in order that the promise may rest on grace and be guaranteed to all his descendants, not only to the adherents of the law but also to those who share the faith of Abraham (for he is the father of all of us,
17 as it is written, "I have made you the father of many nations")-in the presence of the God in whom he believed, who gives life to the dead and calls into existence the things that do not exist. 18 Hoping against hope, he believed that he would become "the father of many nations," according to what was said, "So numerous shall your descendants be." 19 He did not weaken in faith when he considered his own body, which was already as good as dead (for he was about a hundred years old), or when he considered the barrenness of Sarah's womb. 20 No distrust made him waver concerning the promise of God, but he grew strong in his faith as he gave glory to God, 21 being fully convinced that God was able to do what he had promised. 22 Therefore his faith "was reckoned to him as righteousness."
23 Now the words, "it was reckoned to him," were written not for his sake alone, 24 but for ours also. It will be reckoned to us who believe in him who raised Jesus our Lord from the dead, 25 who was handed over to death for our trespasses and was raised for our justification.

(Read Romans 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," 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.
Commentary on Romans 4:13-22
(Read Romans 4:13-22)
The promise was made to Abraham long before the law. It points at Christ, and it refers to the promise, Genesis 12:3. In Thee shall all families of the earth be blessed. The law worketh wrath, by showing that every transgressor is exposed to the Divine displeasure. As God intended to give men a title to the promised blessings, so he appointed it to be by faith, that it might be wholly of grace, to make it sure to all who were of the like precious faith with Abraham, whether Jews or Gentiles, in all ages. The justification and salvation of sinners, the taking to himself the Gentiles who had not been a people, were a gracious calling of things which are not, as though they were; and this giving a being to things that were not, proves the almighty power of God. The nature and power of Abraham's faith are shown. He believed God's testimony, and looked for the performance of his promise, firmly hoping when the case seemed hopeless. It is weakness of faith, that makes a man lie poring on the difficulties in the way of a promise. Abraham took it not for a point that would admit of argument or debate. Unbelief is at the bottom of all our staggerings at God's promises. The strength of faith appeared in its victory over fears. God honours faith; and great faith honours God. It was imputed to him for righteousness. Faith is a grace that of all others gives glory to God. Faith clearly is the instrument by which we receive the righteousness of God, the redemption which is by Christ; and that which is the instrument whereby we take or receive it, cannot be the thing itself, nor can it be the gift thereby taken and received. Abraham's faith did not justify him by its own merit or value, but as giving him a part in Christ.
Commentary on Romans 4:23-25
(Read Romans 4:23-25)
The history of Abraham, and of his justification, was recorded to teach men of after-ages; those especially to whom the gospel was then made known. It is plain, that we are not justified by the merit of our own works, but by faith in Jesus Christ and his righteousness; which is the truth urged in this and the foregoing chapter, as the great spring and foundation of all comfort. Christ did meritoriously work our justification and salvation by his death and passion, but the power and perfection thereof, with respect to us, depend on his resurrection. By his death he paid our debt, in his resurrection he received our acquittance, Isaiah 53:8. When he was discharged, we, in Him and together with Him, received the discharge from the guilt and punishment of all our sins. This last verse is an abridgement or summary of the whole gospel.
