The epistles speak clearly of the activities and strategies of Satan, which is where we learn all we need to know in order to resist him. The activities and existence of the dark entities you speak of are what I think can only be speculation on our part.Which is more or less what Perg and I are saying. Do "gods" exist in the sense like Zeus? Of course not. Do dark entities exist today who have mind and will? Of course. That's Biblical Supernaturalism 101.
