What the Bible says about Price of Forgiveness

Psalm 51:18-19

Essentially, David is saying that the offering of an animal does not meet the price of forgiveness, but an acceptable sacrifice before God is a broken and contrite heart. An acceptable sacrifice is repentance, as it is giving up human nature, its own will, and obstinacy and pride. They have been suppressed and then replaced by humility. This is personally costly because it motivates one to submit his life to God.
