Jesus isn't suffering day after day for your sin. He sits triumphantly at the right hand of God and has won the final and decisive victory for you. If constant lamenting over your sin could actually help you atone for it, then it would be a noble act. However, since there is nothing to be added to your salvation and your agony contributes nothing to your salvation or sanctification, then you are free to walk through life with confidence in your forgiveness. Godly sorrow for sin does not lead to self-condemnation and attempts to atone for your sins through acts of penance. Godly sorrow leads to repentance, which leads us to the cross. There we see, once again, the beautiful sufficiency of our marvelous Savior. Godly sorrow leads us on to a big party, another glorious celebration of the truth of the gospel.
