Romans 4:3-5

Darby Translation

³ for what does the scripture say? And Abraham believed God, and it was reckoned to him as righteousness.

⁴ Now to him that works the reward is not reckoned as of grace, but of debt:

⁵ but to him who does not work, but believes on him who justifies the ungodly, his faith is reckoned as righteousness.
