"I have swept away your offenses like a cloud,
your sins like the morning mist.
Return to me,
for I have redeemed you," says the LORD.
There is no greater love than that of the Father in his Son Jesus Christ, who died for us. We all sin and are powerless to help ourselves. He forgives our sin, that is why He died, and as Christians that is why we must forgive the unforgiveable.
