Romans 4:11-13

Lexham English Bible

¹¹ And he received the sign of circumcision as a seal^[a] of the righteousness by faith which he had while uncircumcised^[b], so that he could be the father of all who believe although they are uncircumcised^[c], so that righteousness could be credited to them,^{[d] 12} and the father of those who are circumcised^[e] to those who are not only from the circumcision, but who also follow in the footsteps of the faith of our father Abraham which he had while uncircumcised^[f].

The Promise to Abraham Secured through Faith

¹³ For the promise to Abraham or to his descendants, that he would be heir of the world, was not through the law, but through the righteousness by faith.
