[Egekrusher]

I never had any question as to what you were saying in the first place.

And as to the original question- I believe that if there is a God, he has no true form. He is more an energy being than anything else.

As for Satan- As stated before, he is a trickster, a prankster, very sly and cunning. I'm guessing that he would be very handsome, dresses in Armani suits, and is very, very charming. The thing is, the devil can't MAKE you do anything, he can only try to talk you into doing it, so he has to use every resource at hand.
