What shall we say then that Abraham our father, as pertaining to the flesh, has found?

AD 400
After showing that no one can be justified before God by the works of the law, Paul goes on to say that Abraham could not merit anything according to the flesh either. In saying “the flesh,” Paul meant circumcision, because Abraham sought nothing on the basis of his circumcision. For he was already justified before he was circumcised. Commentary on Paul’s Epistles.

For it does not seem fitting to say that he found no usefulness, since it is stated in Isaiah 48(:17), "I am the Lord, your God, who teaches you useful things." 323. Secondly, when he says, For if Abraham, he answers the questi...
