Romans 4:4-6

When people work, their pay is not given as a gift, but as something earned. But people cannot do any work that will make them right with God. So they must trust in him, who makes even evil people right in his sight. Then God accepts their faith, and that makes them right with him. David said the same thing. He said that people are truly blessed when God, without paying attention to their deeds, makes people right with himself.
