16 Because of this, it is by faith, in order that it may be according to grace, so that the promise may be secure to all the descendants, not only to those of the law, but also to those of the faith of Abraham, who is the father of us all
17 (just as it is written, “I have made you the father of many nations”) before God, in whom he believed, the one who makes the dead alive and who calls the things that are not as though they are,
18 who against hope believed in hope, so that he became the father of many nations, according to what was said, “so will your descendants be.”
19 And not being weak in faith, he considered his own body as good as dead, because he was approximately a hundred years old, and the deadness of Sarah’s womb.
20 And he did not waver in unbelief at the promise of God, but was strengthened in faith, giving glory to God
21 and being fully convinced that what he had promised, he was also able to do.
22 Therefore it was credited to him for righteousness.
