Romans 4:13-25 - The Promise To Abraham Secured Through Faith
13 For not by the law [came] the promise to Abraham and his seed, that he should be heir of the world, but by the righteousness of faith. 14 For if they who are of the law are heirs, faith becomes vain, and the promise is useless: 15 for the law causeth wrath: for where there is no law, neither is there transgression.
16 Therefore it is by faith, that it might be of grace; in order that the promise might be secured to all the seed; not only to that which is of the law, but to that which is of the faith of Abraham; who is the father of us all, 17 (as it is written "that I have constituted thee father of many nations,") before God, in whom he trusted, who quickeneth the dead, and calleth things that are not as if existing. 18 Who contrary to hope, in hope believed, that he should be the father of many nations, according to what was said, "So shall thy seed be." 19 And not being weak in faith, he regarded not his own body now deadened, being about an hundred years old, nor the deadness of Sarah's womb: 20 for he disputed not against the promise of God with unbelief; but was mighty in faith, giving glory to God; 21 and enjoyed the fullest assurance, that what he had promised, he was able also to perform. 22 And therefore it was imputed to him for righteousness. 23 Now it was not written for his sake only, that it was imputed to him; 24 but also for our sakes, to whom it will be imputed, if we believe in him who raised up Jesus our Lord from the dead; 25 who was delivered up for our offences, and was raised again for our justification.
