I find the accounts of demon possesion in the Bible contradictory to what Jude and Peter write about the demons being in Tarturus, restrained under dense darkness.
What kind of a restraint is it when they possess and harrass human beings?
Also, if you take everything literally written in the Bible, it is clearly spirit creatures which screwed up humanity. A spirit creature deceived Eve who then brings forth sin and death to ALL HUMANS!
Spirit creatures took human bodies and fathered Nephilim who filled the Earth with voilence so God destroyed ALL THE HUMANS!!!----- but the demons escaped.
Then the demons, although in chains, somehow manage to possess human bodies, serve as protectors of kingdoms, challenge righteous angels over the body of Moses, etc.... and
then Paul says humans have a wrestling not with flesh and blood but with the wicked spirit forces!!! Aren't they in jail? Did they get paroled? And WHY do humans
pay the price for the trouble these guys stirred up?
The more you think of it, the more like Greek mythology it sounds, from Zeus to Prometheus, to Hercules---- Son of a God and a mortal and possessing super human strength.
