Romans 4:16-21

New Revised Standard Version Updated Edition

¹⁶ For this reason the promise depends on faith, in order that it may rest on grace, so that it may be guaranteed to all his descendants, not only to the adherents of the law but also to those who share the faith of Abraham (who is the father of all of us,^{(A) 17} as it is written, “I have made you the father of many nations”), in the presence of the God in whom he believed,^[a] who gives life to the dead and calls into existence the things that do not exist.^{(B) 18} Hoping against hope, he believed that he would become “the father of many nations,” according to what was said, “So shall your descendants be.” ¹⁹ He did not weaken in faith when he considered his own body, which was already^[b] as good as dead (for he was about a hundred years old), and the barrenness of Sarah’s womb.^{(C) 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.^(D)
