Blessed are the Believers

Rom 4:3,5-7
What does Scripture say? "Abraham believed God, and that faith was regarded by God to be his approval of Abraham." However, when people don't work but believe God, the one who approves ungodly people, their faith is regarded as God's approval. David says the same thing about those who are blessed: God approves of people without their earning it. David said,
"Blessed are those whose disobedience is forgiven and whose sins are pardoned".
