Romans 4:16-25

Because of this, it is from faith according to grace that the Promise is ensured for all posterity, not only for those who are of the law, but also for those who are of the faith of Abraham, who is the father of us all before God, in whom he believed, who revives the dead and who calls those things that do not exist into existence. For it is written: "I have established you as the father of many nations." And he believed, with a hope beyond hope, so that he might become the father of many nations, according to what was said to him: "Thus shall your posterity shall be." And he was not weakened in faith, nor did he consider his own body to be dead (though he was then almost one hundred years old), nor the womb of Sarah to be dead. And then, in the Promise of God, he did not hesitate out of distrust, but instead he was strengthened in faith, giving glory to God, knowing most fully that whatever God has promised, he is also able to accomplish. And for this reason, it was reputed to him unto justice. Now this has been written, that it was reputed to him unto justice, not only for his sake, but also for our sake. For the same shall be reputed to us, if we believe in him who raised up our Lord Jesus Christ from the dead, who was handed over because of our offenses, and who rose again for our justification.
