16 Therefore, the promise comes by faith, that it may be according to grace, so that it might be guaranteed to all the offspring—not only to those who are of the law, but also to those who share the faith of Abraham, who is the father of us all.
17 As it is written: 'I have made you a father of many nations.' He is our father in the sight of God, in whom he believed—the God who gives life to the dead and calls things that are not as though they were.
18 Against all hope, Abraham in hope believed, so that he became the father of many nations, just as it had been said to him, 'So shall your offspring be.'
19 And without weakening in faith, he did not consider his own body, which was as good as dead—since he was about a hundred years old—or the deadness of Sarah’s womb.
20 He did not waver in unbelief concerning the promise of God, but he was strengthened in faith, giving glory to God,
21 being fully convinced that God was able to do what He had promised.
22 Therefore, it was credited to him as righteousness.
23 Now the words 'it was credited to him' were not written for his sake alone,
24 but also for us, to whom it will be credited—to those who believe in Him who raised Jesus our Lord from the dead.
