Romans 4:2-5 Revised Standard Version (RSV)
2 For if Abraham was justified by works, he has something to boast about, but not before God. 3 For what does the scripture say? “Abraham believed God, and it was reckoned to him as righteousness.” 4 Now to one who works, his wages are not reckoned as a gift but as his due. 5 And to one who does not work but trusts him who justifies the ungodly, his faith is reckoned as righteousness.
