Romans 4:13-25 - The Promise To Abraham Secured Through Faith
13 For the promise to Abraham or his seed, that he should be the heir of the world, was not through the law, but through the righteousness of faith. 14 For if the heirs were by the law, faith has been made void, and the promise vitiated. 15 For the law works out wrath: for where there is no law, there is no transgression.
16 Therefore it is by faith, in order that it may be by grace; that the promise may be sure to all the seed; not only of the law, but also of the faith of Abraham; who is the father of us all, 17 as it has been written, That I have constituted thee the father of many nations, before God whom he believed, who quickens the dead, and calls things which are not as really existing: 18 who against hope confided in hope, that he should be the father of many nations, according to that which had been spoken, So shall thy seed be: 19 and being not weak in faith, he considered not his body already dead, being about a hundred years old, and the deadness of Sarah's womb: 20 but he staggered not at the promise of God through unbelief; but was filled up with dynamite through faith, having given glory to God; 21 and being fully assured, that whatsoever he has promised, he is able also to perform. 22 Therefore it was indeed imputed unto him for righteousness. 23 And it was not written on account of him alone, that it was imputed to him; 24 but on account of us also, to whom it is about to be imputed, who believe on him who raised up our Lord Jesus from the dead; 25 who was delivered on account of our transgressions, and raised for our justification.
