Romans 4:16-21

MLV(i) 16 Because of this, it is from faith, in order that it may be according to grace; that the promise may be steadfast to all the seed; not to what is only from the law, but also to what is from the faith of Abraham, who is the father of us all, 17 (as it has been written, ‘I have placed you as a father of many nations’), in front of God, the one whom he believed, who is giving-life to the dead and is calling the things which are not, as though they are. 18 Abraham who contrary to hope believed upon hope, that he might become a father of many nations, according to what had been spoken, So your seed will be.
19 And not being weak in faith, he did not consider his own body, already sterile, (being nearly a hundred years), and the deadness of Sarah’s womb. 20 But he did not doubt through unbelief at the promise of God, but became empowered through faith, having given glory to God, 21 and being fully assured that what he has promised; he is able also to do.
