Romans 4:13-17

The promise to Abraham and to his offspring that he would be heir of the world, was not through the law, but through the righteousness of faith. For if those who are of the law are heirs, faith has no value, and the promise is nullified, because the law brings wrath. Where there is no law, there is no disobedience. The promise comes by faith, that it may be of grace, and guaranteed to all of the seed - not only to those who are of the law, but also to those who are of the faith of Abraham, who is the father of us all. GOD said, "I have made you the father of many nations," because Abraham believed GOD - the GOD who gives life to the dead, and calls things into existence that never were before.
