Romans 4
2 Ref For if Abraham were justified by works, he hath whereof to glory; but not before God.
3 Ref For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness.
4 Ref Now to him that worketh is the reward not reckoned of grace, but of debt.
5 Ref But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.
