Do we suppose that the Bible tells us EVERYTHING about demons? No. But it does tell us all we NEED to know (namely, that they have to go in the Name of Jesus, etc.). For instance, wouldn't you like to know more about why the demons wanted to go into the swine? What we have is mainly conjecture.Wouldn't you like to know where demons come from? Some say they are fallen angels, etc. But to the best of my knowledge, that it nothing but conjecture, too.However, when someone speaks of a Jezebel spirit, I do not take this to be a particular DEMON, but rather a set of behaviors that can enable us to be more watchful with people exhibiting those behaviors. Just as the FBI has profilers that can tell us the traits of certain serial killers (believe it or not, cruelty to animals, bed-wetting, and fire starting are three things that show up in many or most serial killer profiles!), we would be foolish to ignore behaviors that often reveal darker things.The same with the Jezebel spirit. Like I said, I have never considered that a particular demon, but rather someone who is acting in a way that we believe Jezebel acted. Just as we can see people that are controlling, or insecure, or narcissistic--and can divine from that certain elements that we would be wise to regard in the future with other people/situations--so, too, can we see both negative and positive traits in Biblical characters and draw some conclusions.For instance, do you recall how Jesus told the disciples (who wanted to call down fire from heaven) that they didn't know what spirit they were of? He is letting them know that they were acting in a manner that was contrary to the pattern/spirit they should have been following.Now, sometimes, it does indeed get weird. And perhaps this is something that can only be detected by discernment, but, yeah, sometimes people go to some wild places in their teaching, and in such cases, we must take care. I tend to take many things with a grain of salt, not giving exceptional weight to it until I can better study it or confirm it, etc.Most of us preach sermons that are based on these principles. For instance, we may not call it the spirit of Esau, we might very well preach a sermon about people who trade their birthright for some bauble, relatively speaking. Demas? I think we could EASILY come up with a spirit of Demas. But I think the use of the word spirit can get problematic, making people think it is a specific spirit with a specific name, rather than a profile that often accompanies people who turn back to the world.In our mid-week Bible Study, going through the stories of the Bible, we spoke of Jezebel. And I simply pointed out some key things that Jezebel exhibited and warned against such things. I might have used the term Jezebel spirit, but I think it was clear that I meant actions associated very strongly with Jezebel.
