16 That is why it depends on faith, in order that the promise may rest on grace and be guaranteed to all his offspring—not only to the adherent of the law but also to ^dthe one who shares the faith of Abraham, who is the father of us all, 17 as it is written, ^e“I have made you the father of many nations”—in the presence of the God ^fin whom he believed, who ^ggives life to the dead and calls into existence the things that do not exist. 18 In hope he believed against hope, that he should become the father of many nations, as he had been told, ^h“So shall your offspring be.” 19 He did not weaken in faith ⁱwhen he considered his own body, which was ^jas good as dead (since he was about ^ka hundred years old), or when he considered the barrenness¹ of Sarah’s womb. 20 No ^lunbelief 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 God was able to do what he had promised.
