Romans 4:13-17

13For the promise to Abraham and his offspring that he would be heir of the world was not given through the law, but through the righteousness that comes by faith. 14For if those who live by the law are heirs, faith is useless and the promise is worthless, 15because the law brings wrath. And where there is no law, there is no transgression.

16Therefore, the promise comes by faith, so that it may rest on grace and may be guaranteed to all Abraham’s offspring—not only to those who are of the law, but also to those who are of the faith of Abraham. He is the father of us all. 17As it is written: “I have made you a father of many nations.”1 He is our father in the presence of God, in whom he believed, the God who gives life to the dead and calls into being what does not yet exist.
