What you fail to realize is that the Satan explanation for the experience of other gods works just as well against your god. Allah is the one true god, and anyone that sees Jesus or Yaweh is just being deceived by Satan. See? It is impossible for you to refute that without relying on some sort of belief, i.e. the bible says differently.
Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own - Bertrand Russell
