What about those in psychiatric institutions who no one can seem to help? Is it because some (not all) of these people may be demonized but no one is willing to consider this as a possibility and so they remain in bondage (and drugged up on medication).
What about those who practice occultism such as magick, spell casting, and calling upon spirit guides, etc? Are they opening themselves up to the risk of demonic possession?
And what about the Church? How many Christians today believe in this phenomena and how many would be willing to deal with it if they came across it today?
