“Some are without any doubt but the floodgates will be opened..I think it could be Demons flood in from another plane..”
I don’t know or think that God would allow that. I think they are already here and have been from the beginning. Death is just another dimension or “plane of existence”... and God hasn’t, to my knowledge, allowed anyone to come back from that other dimension, from the dead, to fight against His people yet.
By that point God has left the room and turned the Earth over to Satan. Will people be saved yes but will immediately pay with their life’s.
