Romans 4:13-18

13For the promise to Abraham and his offspring that he would be heir of the world did not come through the law but through the righteousness of faith. 14For if it is the adherents of the law who are to be the heirs, faith is null and the promise is void. 15For the law brings wrath, but where there is no law there is no transgression. 16That is why it depends on faith, in order that the promise may rest on grace and be guaranteed to all his offspring—not only to the adherent of the law but also to the one who shares the faith of Abraham, who is the father of us all, 17as 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. 18In hope he believed against hope, that he should become the father of many nations, as he had been told, “So shall your offspring be.”
