11 He was circumcised later, and his circumcision was a sign to show that because of his faith God had accepted him as righteous before he had been circumcised. And so Abraham is the spiritual father of all who believe in God and are accepted as righteous by him, even though they are not circumcised.
12 He is also the father of those who are circumcised, that is, of those who, in addition to being circumcised, also live the same life of faith that our father Abraham lived before he was circumcised.
13 When God promised Abraham and his descendants that the world would belong to him, he did so, not because Abraham obeyed the Law, but because he believed and was accepted as righteous by God.
14 For if what God promises is to be given to those who obey the Law, then faith means nothing and God's promise is worthless.
15 The Law brings down God's anger; but where there is no law, there is no disobeying of the law.
16 And so the promise was based on faith, in order that the promise should be guaranteed as God's free gift to all of Abraham's descendants—not just to those who obey the Law, but also to those who believe as Abraham did. For Abraham is the spiritual father of us all;
17 as the scripture says, “I have made you father of many nations.” So the promise is good in the sight of God, in whom Abraham believed—the God who brings the dead to life and whose command brings into being what did not exist.
