Romans 4:3

3 What does Scripture say? “Abraham believed God, and it was credited to him as righteousness.”

Romans 4:11

11 And he received circumcision as a sign, a seal of the righteousness that he had by faith while he was still uncircumcised. So then, he is the father of all who believe but have not been circumcised, in order that righteousness might be credited to them.

Romans 4:2

2 If, in fact, Abraham was justified by works, he had something to boast about—but not before God.
