Is there any doubt that demons exist? This Quest does not set out to convince anyone that demons are real. Instead, we are going to look behind the curtain at "the great and powerful Oz." My first awareness that demons were quite active in our lives came when I found out that my 4 year old son was suffering at their hands every night when he closed his eyes. Not only that, but could see things in the spirit that I could not see, and was petrified by an experience he had with them while awake.
