You must confess your sins to God. Yes, He already knows you committed them. In addition, He already knew you were going to commit them. Why do you need to confess if God already knows all the sins you committed and will ever commit? You do it as an act of obedience and sincerity to God. You must confess to God and ask that He forgive you for your sins. He will.
You must also confess your sins to each other. I don’t mean the people you wrong. I mean your brothers and sisters in Christ. Yes, this may be a little more difficult. It shouldn’t be. After all, who here on earth has the power to save, condemn, or forgive sins? No one. Therefore, it should be a lot easier to confess to others.
Even though it may be difficult, you must still confess to your brothers and sisters in Christ. The reason for this is so that they can pray for you and help you overcome your sin. You need to be willing to be vulnerable. Be willing to find fellow Christians that you trust so that you may confide in them.
The act of confessing your sins to another person is something that may really help you deal with the negative emotions and feelings associated with those sins. In addition, if you are struggling with something, you need all the prayer and support you can get.
