Fortune Tellers The practice of fortune telling is forbidden by God. It's in the Bible, Deuteronomy 18:9-13 The future is known only by God. It's in the Bible, Isaiah 8:19, TLB. "So why are you trying to find out the future by consulting witches and mediums. Don't listen to their whisperings and mutterings. Can the living find out the future from the dead? Why not ask your God?"
