"So long as the Lord does not live in you, all beings hold darkness in their hearts". I suppose that sentiment goes true in that regard.

Blind adoration and following is a fool's errand; that much is true. Humans have lost their connection to nature, and to the supernatural. This is the cause of most demonic outbreaks.

Without belief, demons too shall falter and die.

And their rage against the humans can be fierce.

Your God may be different. Or He may even be gone. But if you wish, I will speak of mine to you.
