Mental Illness Versus Demon Possession

Considering my stance that having a mental illness does not mean the sufferer is possessed by demons, I thought providing some support for my belief would be helpful.

12 Ways Mental Illness is DIFFERENT than Demon Possession


** NOTE **

While I only included the relevant parts of these verses, I highly recommend reading the background of the section for context.


(as based in Scripture)
  • Not treatable except by prayer/casting out
  • (Might) Have strength beyond the normal human scope



(based on Scripture, some scientific knowledge, and also personal experience both with myself and others I know/have known who suffer with a mental illness)
  • Treatable by medicine and therapy
  • People with less severe forms can act like they’re not ill (seem normal).
  • There are those suffering with a mental illness that become highly religious or obsessed with the Bible
  • King Nebuchadnezzar suffered possible mental illness symptoms and says, “at that time my sanity returned to me …” (v.36)
  • For “wickedness” and abandoning God, the Bible says various curses and punishments that will befall the person (or people), including “madness” and “mental confusion” (v.28)
    • Deuteronomy 28:28
    • If this “madness” could happen to non-Christians it can happen to us because sin is in the world.




It is also noteworthy that seizures are easily explained (for the most part) scientifically today – most people do not connect seizures and possession by demons at all. If you read Scriptures, though, there are cases in which seizures were caused by demonic possession:

If not all (or even most) cases of epilepsy or other seizures are caused by demons, why would we think that all (or most) cases of mental illness are caused by demons?


Furthermore, this post would not be complete without mention of cutting. Yes, cutting has been associated with possession by demons:


The Bible also specifically addresses cutting as something to avoid:


Cutting being addressed so specifically is important, because someone who is demon possessed would not be able to follow such a command. The demon within the person would be making the decisions. Would a demon even read the Bible? For the most part, demons wanted nothing to do with Jesus. Frequently when Jesus interacted with demons, we see them asking Him not to torment them:


Hopefully this (very long) post has addressed any questions or doubts you might have had previously. While I’m sure this is by no means an exhaustive list of differences between mental illness and possession by demons (or a listing of all possible Scripture references), maybe having it out ‘there’ will clear up some confusion.
