Romans 4:18-22

18In hope against hope he believed, so that he might become 1a father of many nations according to that which had been spoken, “2So shall your 3descendants be.”

19Without becoming weak in faith he contemplated his own body, now 4as good as dead since 5he was about a hundred years old, and 6the deadness of Sarah’s womb;

20yet, with respect to the promise of God, he did not waver in unbelief but grew strong in faith, 7giving glory to God,

21and 8being fully assured that 9what God had promised, He was able also to perform.

22Therefore 10it was also credited to him as righteousness.
