The practice of fortune telling is forbidden by God. It's in the Bible, Deuteronomy 18:9-13, TLB. "When you arrive in the Promised Land you must be very careful lest you be corrupted by the horrible customs of the nations now living there. For example, an Israeli who presents his child to be burned to death as a sacrifice to heathen gods, must be killed. No one may practice black magic, or call on the evil spirits for aid, or be a fortune teller, or be a serpent charmer, medium, or wizard, or call forth the spirits of the dead. Anyone doing these things is an object of horror and disgust to the Lord, and it is because the nations do these things that the Lord your God will displace them. You must walk blamelessly before the Lord your God."

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?"
