Romans 4:4

4:4 Now to the one who works, his pay is not credited due to grace but due to obligation.

Romans 4:9-10

4:9 Is this blessedness then for the circumcision or also for the uncircumcision? For we say, “faith was credited to Abraham as righteousness.” 4:10 How then was it credited to him? Was he circumcised at the time, or not? No, he was not circumcised but uncircumcised!
