9Is this blessing only on the circumcised, or also on the uncircumcised? We have been saying that Abraham’s faith was credited to him as righteousness.
11And he received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. So then, he is the father of all who believe but are not circumcised, in order that righteousness might be credited to them.
12And he is also the father of the circumcised who not only are circumcised, but who also walk in the footsteps of the faith that our father Abraham had before he was circumcised.
13For the promise to Abraham and his offspring that he would be heir of the world was not given through the law, but through the righteousness that comes by faith.
16Therefore, the promise comes by faith, so that it may rest on grace and may be guaranteed to all Abraham’s offspring—not only to those who are of the law, but also to those who are of the faith of Abraham. He is the father of us all.
17As it is written: “I have made you a father of many nations.” He is our father in the presence of God, in whom he believed, the God who gives life to the dead and calls into being what does not yet exist.
19Without weakening in his faith, he acknowledged the decrepitness of his body (since he was about a hundred years old) and the lifelessness of Sarah’s womb.
