But make no mistake, Satan's churches and religions DO have great power and charisma. Sometimes the difference is quite large. Some of Satan's churches will even send you a free copy of the KJV Bible. My friend Jesus was a really nice guy, but believing in him would NOT get you to heaven. For if he who comes preaches another Jesus whom we have not preached, or if you receive a different spirit which you have not received, or a different gospel which you have not accepted, you may well put up with it.

A person may be speaking to you from a lectern or pulpit whereon rests a Bible. That person may seem very sincere. He may extensively quote from the Bible. He may repeatedly invoke the name of Jesus. Satan most definitely has his OWN preachers and teachers, and they twist God's word to their own destruction.
