Romans 4
2 Ref For if Abraham got righteousness by works, he has reason for pride; but not before God.
3 Ref But what does it say in the holy Writings? And Abraham had faith in God, and it was put to his account as righteousness.
4 Ref Now, the reward is credited to him who does works, not as of grace but as a debt.
5 Ref But to him who without working has faith in him who gives righteousness to the evil-doer, his faith is put to his account as righteousness.
