Jesus Himself set one order of spirits apart from all other spirits. The first clue we were given about this particular spirit is in Matthew 17:21, when Jesus declared this spirit to be different. (If you failed to find the 21st verse of Matthew in your Bible, look in another version. In some of the later versions they have taken this verse out of the Bible! I assure you it is in the original!) Anytime our Lord talks about a spirit being different, we should perk up and pay attention. He did not do this for conversation’s sake, it is an important revelation in our preparation for spiritual warfare.
