13  For it was not by law that the promise was to Abraham, or to his seed, that he should be heir of the world, but by righteousness of faith. 14  For if they which are of law be heirs, faith is made vain, and the promise made of no effect. 15  For law works wrath; but where no law is neither is there transgression. 16  Therefore it is on the principle of faith, that it might be according to grace, in order to the promise being sure to all the seed, not to that only which is of the law, but to that also which is of Abraham’s faith, who is father of us all,

17  (according as it is written, I have made thee father of many nations,) before the God whom he believed, who quickens the dead, and calls the things which be not as being; 18  who against hope believed in hope to his becoming father of many nations, according to that which was spoken, So shall thy seed be: 19  and not being weak in faith, he considered not his own body already become dead, being about a hundred years old, and the deadening of Sarah’s womb, 20  and hesitated not at the promise of God through unbelief; but found strength in faith, giving glory to God; 21  and being fully persuaded that what he has promised he is able also to do; 22  wherefore also it was reckoned to him as righteousness.
