One of the most common mistakes people make is asking God for forgiveness rather than repenting of their sins and going through deliverance. Jesus forgave you when he died on the cross and rose again. By accepting him as your Lord and Savior you are forgiven, but that doesn't mean that all your spiritual baggage has been cast off yet. Deliverance rids you of that spiritual baggage that is causing you so many problems. Hopefully this video will help.
