Romans 4:18-25

18 In hope he believed against hope, that he should become the father of many nations, as he had been told, 1"So shall your offspring be."
19 He did not weaken in faith when he considered his own body, which was 2as good as dead (3since he was about a hundred years old), or when he considered 4the barrenness of Sarah's womb.
20 No distrust made him waver concerning the promise of God, but he grew strong in his faith as he gave glory to God,
21 fully convinced that 5God was able to do what he had promised.
22 That is why his faith was "counted to him as righteousness."
23 But 6the words "it was counted to him" were not written for his sake alone,
24 but for ours also. It will be counted to us 7who believe in 8him who raised from the dead Jesus our Lord,
25 9who was delivered up for our trespasses and raised 10for our justification.
