16. Therefore by faith, that it might be by grace, to the end the promise might be sure to all the seed, not only to that which is of the law, but also to that which is of the faith of Abraham, who is the father of us all,
17. as it is written, As a father of many Gentiles have I placed thee before God, whom he believed, who gives life to the dead and calls those things which are not as those that are.
18. Who believed to wait against all hope, that he might become the father of many Gentiles, according to that which had been spoken unto him, So shall thy seed be.
19. And he did not weaken in faith: he considered not his own body now dead when he was about one hundred years old, neither yet the deadness of Sara’s womb;
20. he doubted not the promise of God, with unbelief, but was strengthened in faith, giving glory to God,
21. being fully persuaded that he was also powerful to do all that he had promised;
22. therefore, his faith was also attributed unto him as righteousness.
