Is god supposed to be a supernatural being? A couple of things come to mind when people say god has to be supernatural. One that god has to be outside our understanding or from the opposite spectrum that supernatural doesn't exist therefore god doesn't exist. Can god be natural or is that something that nullifies any aspect of the term god?
Perhaps these definitions for supernatural are enough to discuss.
