Romans 4:16-24

16This is why the promise is by faith, so that it may be according to grace, to guarantee it to all the descendants  — not only to the one who is of the law but also to the one who is of Abraham’s faith. He 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, the one who gives life to the dead and calls things into existence that do not exist.

18He believed, hoping against hope, so that he became the father of many nations according to what had been spoken: So will your descendants be.

19He did not weaken in faith when he considered his own body to be already dead (since he was about a hundred years old) and also the deadness of Sarah’s womb.

20He did not waver in unbelief at God’s promise but was strengthened in his faith and gave glory to God,

21because he was fully convinced that what God had promised, he was also able to do.

22Therefore, it was credited to him for righteousness.

23Now it was credited to him was not written for Abraham alone,

24but also for us. It will be credited to us who believe in him who raised Jesus our Lord from the dead.
