Romans 4:17-19

Goodspeed(i) 17 as the Scripture says, "I have made you the father of many nations." The promise is guaranteed in the very sight of God in whom he had faith, who can bring the dead to life and call into being what does not exist. 18 Abraham, hoping against hope, had faith, and so became the father of many nations, in fulfilment of the Scripture, "So countless shall your descendants be." 19 His faith did not weaken, although he realized that his own body was worn out, for he was about a hundred years old, and that Sarah was past bearing children.
