My husband was raised catholic and he was telling me today how the one thing he did like about it was how he could talk about everything he did wrong (in confession) and not get in trouble for it. It's interesting how he felt that way and yet didn't realize all these years we have been Christian with no denomination that he had his own personal confession. He could confess to the king of kings and not be in trouble. Because of Jesus Christ we are not condemned for our sins. Because of Jesus, it's okay for people to come straight to God and confess their sins. There is no need for a imperfect human mediator. Jesus is the mediator. Jesus can be our mediator because He came to earth as the only perfect person and took on all our sins.
It's easy to forget that when you felt as if you done something terrible. You want to hide and hope God didn't see. But He did see, and if you ask, He will forgive.
Therefore, there is now no condemnation for those who are in Christ Jesus, because through Christ Jesus the law of the Spirit of life set me free from the law of sin and death.
