Romans 4:18-22

4:18 Against hope Abraham believed in hope with the result that he became the father of many nations according to the pronouncement, “so will your descendants be.” 4:19 Without being weak in faith, he considered his own body as dead (because he was about one hundred years old) and the deadness of Sarah’s womb. 4:20 He did not waver in unbelief about the promise of God but was strengthened in faith, giving glory to God. 4:21 He was fully convinced that what God promised he was also able to do. 4:22 So indeed it was credited to Abraham as righteousness.
