Now look how beautifully David combines these two things: first, that God is merciful, that is, that He freely blesses us undeserving ones; second, that He gives us the forgiveness of sins, which we accept by faith through the Holy Spirit and His promises. If God did not freely forgive, we should have no satisfaction and no remedy left. Not by our fasting nor by other works, not by angels nor by any other creature, is there salvation. Our only salvation is if we flee to the mercy of God and seek blessing and forgiveness from God, asking Him not to look at our sins and transgressions, but to close His eyes and to deal with us according to His steadfast love and abundant mercy. Unless God does this, we are not worthy of being granted one hour of life or one morsel of bread.
