16Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the seed; not to that only which is of the law, but to that also which is of the faith of Abraham; who is the father of us all,
17As it is written, I have made thee a father of many nations,) before him whom he believed, even God, who quickeneth the dead, and calleth those things which be not as though they were.
18Who against hope believed in hope, that he might become the father of many nations, according to that which was spoken, So shall thy seed be.
19And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sara's womb:
20He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
21And being fully persuaded that, what he had promised, he was able also to perform.
22And therefore it was imputed to him for righteousness.
