Indeed.
I have talked to people who have done deliverance ministries, legitimate ones, and they have said that often people see spiritual warfare as a power struggle, when in reality, it’s a truth struggle.
The worst lies to deal with are the subtle ones, that are mostly truth. Very few people will fall for blatant, out and out lies. It’s too obvious. But mix large amounts of truth in it, and they will often fall for it unsuspecting.
That's what many false religions do......and numerous online ministries.
