Romans 4:3-8

3What does Scripture say? “Abraham believed God, and it was credited to him as righteousness.” Gen. 15:6; also in verse 22 4Now to the one who works, wages are not credited as a gift but as an obligation. 5However, to the one who does not work but trusts God who justifies the ungodly, their faith is credited as righteousness.

6David says the same thing when he speaks of the blessedness of the one to whom God credits righteousness apart from works:

7“Blessed are those whose transgressions are forgiven, whose sins are covered.

8Blessed is the one whose sin the Lord will never count against them.” Psalm 32:1,2
