Romans 4:13-18Revised Standard Version (RSV)
God’s Promise Realized through Faith
13 The promise to Abraham and his descendants, that they should inherit the world, did not come 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 there is no transgression.
16 That is why 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 us all, 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 In hope he believed against hope, that he should become the father of many nations; as he had been told, “So shall your descendants be.”
