Romans 4:9, 11, 13, 22

Is this blessing then pronounced upon the circumcision, or upon the uncircumcision also? for we say, To Abraham his faith was reckoned for righteousness.

and he received the sign of circumcision, a seal of the righteousness of the faith which he had while he was in uncircumcision: that he might be the father of all them that believe, though they be in uncircumcision, that righteousness might be reckoned unto them

For not through the law was the promise to Abraham or to his seed that he should be heir of the world, but through the righteousness of faith.

Wherefore also it was reckoned unto him for righteousness.
