17 (as it is written, “I have made you a father of many nations”) in the presence of Him whom he believed—God, who gives life to the dead and calls those things which do not exist as though they did;
18 who, contrary to hope, in hope believed, so that he became the father of many nations, according to what was spoken, “So shall your descendants be.”
19 And not being weak in faith, he did not consider his own body, already dead (since he was about a hundred years old), and the deadness of Sarah’s womb.
20 He did not waver at the promise of God through unbelief, but was strengthened in faith, giving glory to God,
21 and being fully convinced that what He had promised He was also able to perform.
[New King James Version]
