Romans 4:2-5

King James Version

² For if Abraham were justified by works, he hath whereof to glory; but not before God.

³ For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness.

⁴ Now to him that worketh is the reward not reckoned of grace, but of debt.

⁵ But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.
