Romans 4:18-22

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.
