Is Halloween Dangerous?

I was thinking about the supernatural today. I guess it seems appropriate, since today is Halloween. I was wondering why most American and Western Christians do not think the supernatural rhealm especially the demonic or spirit rhealm is real. So today in, deep contemplation, I asked my wife and she said she thought it was because it is so sensationalized in the media and treated more as entertainment rather than reality. I think it is dangerous for us as Christians to not give any credance to the spirit world, which biblically exists beyond a shadow of a doubt. I remembered the great book by C.S. Lewis called Screwtape Letters in which a senior demon is communicating in a series of letters to his young apprentice called Wormwood. Here is a lengthy quote from the book in which Screwtape describes a great strategy in demonic warfare. Making us Christians think the spirit realm is not real.

"Our policy for the moment, is to conceal ourselves.  Of course this has not always been so.  We are really faced with a cruel dilemma.  When the humans disbelieve in our existences at we lose all the pleasing results of direct terrorism and we make no magicians. On the other hand, when they believe in us, we cannot make them materialists and skeptics.  At least, not yet.  I have great hopes that we shall learn in due time how to emotionalize and mythologize their science to such an extent that what is, in effect, a belief in us (though not under that name) will creep in while the human mind remains closed to belief in the Enemy. …If once we can produce our perfect work – the Materialist Magician, the man, not using, but veritably worshipping, what he vaguely calls ‘Forces’ while denying the existence of ‘spirits’ – then the end of the war will be in sight." (p31)

-C.S. Lewis

Screwtape Letters 

Screwtape writing to Wormwood giving him advice on keeping himself concealed and helping humans continue to disbelieve in the existence of demons

We could also say that our culture doesn't disbelieve in demonic or the supernatural rhealm, but we are just entertained by it. Witchcraft, the occult, and the like are huge selling phenomena in today's entertainment industry. That is even more dangerous. We see these things as practices and religions that entertain us is even more senseless to me. I leave you with a scripture that for us as Christians should sum up our biblical relationship with the adversary. 

For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places. Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm. (Ephesians 6:12, 13 ESV)
