Right, and it's not like by confessing my sins I'm somehow scoring points upstairs. I mean what servant in doing the bare minimum of his duties should expect reward?
The fact of the matter is that God has given us a promise, that if we confess our sins He is faithful and just to forgive us our sins. That's present tense, not some sort of "Oh, I did that already twenty years ago" thing.
When I confess my sins I know God's word and promises are true, that my sins are in fact forgiven, because God has taken me and united me to Christ in my baptism, because Christ has died and Christ has risen, and He sits at the right hand of the Father in heaven. And that all that is Christ's is mine in Him.
Should I not confess my sins, sulking in them or hiding them (as though I could hide them from He who knows even the hairs on my head)? Should I hide them in myself, letting them fester and rot me from the inside? Or should I confess them, repent and cling to the hope and promises of God that are in Christ, clinging to His cross, and cherish the forgiveness I have in Him?
I vote for the latter.
