I resumed our discussion about your "demon possession" experience in this thread:
but I will restate my comment here:
Your sharing your personal experience of "demon possession" made me see why you were quick to read into my comments that I engaged in spiritism or used a Ouija board (though I subsequently learnt that doing these things have nothing to do with the psychic symptoms which I experienced).
After such an experience and finding relief by turning to God, it is understandable why your mind would interpret everything in terms of the "if it is not God then it must be demons" framework/worldview.
There are some things which I find puzzling about "demon possession" however:
God will protect you from demons but he can't protect people in other situations for example, a tree falling on someone and killing them, a fatal lightening strike, someone goes for a swim and unknown to them, inhales some water with a brain eating amoeba, someone goes to wash their hands in a lake when a crocodile/alligator unexpectedly pounces on them, drags them in and kills them etc. etc. etc.
It seems it is more important for God to protect people from demon possession than from these more fatal situations.
Also, some claim that demons don't possess the mentally ill.
Why would the demons be so selective and kind to spare a mentally ill person? It seems the mentally ill/psychologically disturbed have the best defence against demon possession. God gets a break - he doesn't have to worry about protecting such persons from demon possession?
