Do you really think that the message that saves is about not repenting of sins but believing Jesus' blood cleans you of sins you don't even know you do?!
We have to confess our sins with our mouth and repent of them.
Confessing our sins is like a dog chasing it's tail. Never ending. Have you ever tried actually to do this? All your thinking is on sin and not righteousness then.
It's the nature of sin that God deals with in our life. He changes it. We then are the righteousness of God in Christ Jesus. Doesn't mean we are perfect, but are being perfected as we "see" Him. We become like Him when we see Him as He is. Then we may kneel before Him in repentance. But, He lifts us up for His will is to declare His works, not ours. Good or bad. That's the wrong tree.
