Does Satan believe he can defeat God.?
Not sure ,but right now in the USA he is doing a pretty fair job of it.
Now maybe it isn’t a real fight in that God may have just given up on us, but with all of the wins by the ACLU and school prayer and crosses and nativity sets, with the Homo in chief filling our military,and same sex marriage, I would say the battles are going in favor of satan right now.
It would be nice if God took a hand in this game, and soon.
But then we don’t know his real plan, maybe he is waiting for us to take a hand in CW2.
What this discussion is missing is that nothing in creation is out of God’s control, and that includes Satan. Satan, meaning “adversary,” is the adversary of mankind, not of God. Whatever Satan is doing is still part of God’s plan.
