It is one thing to admit that you are wrong about something. It is something else to confess a sin to being a down to the heart & soul sin. The main reason for confessing is to hear it spoken to God, to self and to someone that you can trust. What is this you ask and why? The answer: To show how humble and naked you can be before God. To rid yourself of guilt and shame. After all Jesus died on the cross as the human sacrifice for all of mankind. We should not carry that burden. Matthew 5:8 Happy are the pure at heart. We need to be comfortable knowing that we are going to sin. This is not to say to go out and intentionally do so. But that we are human. Let God know that we know that we have made a mistake and that we have trouble with that. We need to be able to willingly ask for strength so that it does not keep happening. And most importantly forgiving oneself. That takes away the pain and agony. Believe this pain and agony come in various degrees. Depression. Addiction, Violence, Suicide.
Psalm 27:8 My heart says of you seek his face, Oh Lord your face shall I seek.
