Romans 4:1-12

What then shall we say that Abraham, our forefather, hath found according to the flesh? For if Abraham was justified by works, he hath whereof to glory; but not toward God. For what saith the scripture? And Abraham believed God, and it was reckoned unto him for righteousness. Now to him that worketh, the reward is not reckoned as of grace, but as of debt. But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is reckoned for righteousness. Even as David also pronounceth blessing upon the man, unto whom God reckoneth righteousness apart from works, saying, Blessed are they whose iniquities are forgiven, And whose sins are covered. Blessed is the man to whom the Lord will not reckon sin. Is this blessing then pronounced upon the circumcision, or upon the uncircumcision also? for we say, To Abraham his faith was reckoned for righteousness. How then was it reckoned? when he was in circumcision, or in uncircumcision? Not in circumcision, but in uncircumcision: 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; and the father of circumcision to them who not only are of the circumcision, but who also walk in the steps of that faith of our father Abraham which he had in uncircumcision.
