16 So the promise is received by faith. It is given as a free gift. And we are all certain to receive it, whether or not we live according to the law of Moses, if we have faith like Abraham's. For Abraham is the father of all who believe.
17 That is what the Scriptures mean when God told him, "I have made you the father of many nations." This happened because Abraham believed in the God who brings the dead back to life and who creates new things out of nothing. 18 Even when there was no reason for hope, Abraham kept hoping-believing that he would become the father of many nations. For God had said to him, "That's how many descendants you will have!" 19 And Abraham's faith did not weaken, even though, at about 100Â years of age, he figured his body was as good as dead-and so was Sarah's womb. 20 Abraham never wavered in believing God's promise. In fact, his faith grew stronger, and in this he brought glory to God. 21 He was fully convinced that God is able to do whatever he promises. 22 And because of Abraham's faith, God counted him as righteous.
23 And when God counted him as righteous, it wasn't just for Abraham's benefit. It was recorded 24 for our benefit, too, assuring us that God will also count us as righteous if we believe in him, the one who raised Jesus our Lord from the dead. 25 He was handed over to die because of our sins, and he was raised to life to make us right with God.

(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.
