It’s called demonic possession. It’s on the rise here in America....
I think I’ll go ahead and assume drink, drugs, and good old fashioned mental illness before assuming demons. Not because I dispute demons, but because blaming it on them is too easy an out for people’s misbehavior.
Roger that.
Although if one has no concept of "spiritual warfare", then that just means jibberish.
(People hear demonic possession and they think: "oooh, the devil with horns and a pitchfork - ohh, I'm scared...." - they have NO idea).
