Spiritual Blindness I spoke with a "mystic" who owned a shop in my town. At one point in the conversation I had the opportunity to tell her that contacting the spirit world was a dangerous thing to do because she had no control over who or what she contacted. She confidently told me in all the years she has been doing this, she has never come in contact with an evil spirit. I asked, "How would you know? The Bible says even Satan masquerades as an Angel of light." If you are being deceived, you don't know it otherwise you would not be deceived.
