Confession means not only that I Confess my sin with Shame and Repentance, but that I Turn it Over to God, Trusting Him to Take it Away.
Such Confession implies that I am UNABLE to get rid of my guilt UNLESS, by an Act of Faith, I Trust God to Deliver me.
This Deliverance means that I Know my sins are Forgiven and that Christ Undertakes to Cleanse me from the sin and Keep me from its power.
