Romans 4:17-19

Living_Oracles(i) 17 (as it is written, "Surely a father of many nations have I constituted you,") in the presence of him whom he believed, even of God, who makes alive the dead, and calls things which exist not, as though they existed. 18 He, contrary to hope, believed with hope, that he should be a father of many nations, according to what was spoken, "So shall your seed be." 19 And not being weak in faith, he did not consider his own body now dead, being about a hundred years old; neither the deadness of Sarah's womb.
