Romans 4:2-5

2For if Abraham was justified 1by works, he has something to boast about; but 2not 3before God.

3For what does the Scripture say? “4Abraham believed God, and it was credited to him as righteousness.”

4Now to the one who 5works, the wages are not credited as a favor, but as what is due.

5But to the one who does not work, but 6believes in Him who justifies the ungodly, his faith is credited as righteousness,
