Romans 4:2-8 (NKJV)

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 accounted to him for righteousness."
4 "Now to him who works, the wages are not counted as grace but as debt."
5 "But to him who does not work but believes on Him who justifies the ungodly, his faith is accounted for righteousness,"
6 "just as David also describes the blessedness of the man to whom God imputes righteousness apart from works:"
7 "Blessed are those whose lawless deeds are forgiven, And whose sins are covered;"
8 "Blessed is the man to whom the LORD shall not impute sin. "
