I must confess I sometimes enjoy the extravagant and entertaining TV show aired on TLC called "Long Island Medium." Her name is Teresa Caputo, and she seems to pick up pieces of information about people's lives randomly everywhere she goes. She says she is able to talk to people "who have crossed over" meaning they are dead and wish to share information about their loved ones. Sometimes Teresa is invited to a home or gathering for the purpose of the reading, but many times, the event is spontaneous. I wonder if the random nature of these experiences is a marketing technique.
God's guidance in the Bible does not condone this method of seeking knowledge. He says in Isaiah 8:19 When someone tells you to consult mediums and spiritists, who whisper and mutter, should not a people inquire of their God? Why consult the dead on behalf of the living?
In other places the command implies bad consequences for such behavior. Leviticus 20:5-7 compares seeking mediums and spiritists to idolatry. We are commanded not to resort to them. Throughout the Old Testament God ordered cleansing of the land and expulsion of mediums and spiritists. I don't find any reason why he would change now.
Teresa does acknowledge God in a passive, non-committal manner when she says she hopes her readings bring peace and comfort to all the participants, but she does not profess faith in God or seek God's blessing or help. She addresses the source of her power as "Spirit", but she does not view "Spirit" as Holy or in any way akin to God's Holy Spirit.
Teresa does not seem to be very confident of her information or her connection to "Spirit." Maybe the shocked reaction when she questions the subjects and finds that her guesses are correct are just acting for the camera. It's still not what I would expect of someone who knows the future. She does seem to have a genuine concern for the people she deals with, but that may just be a good understanding of psychological impact of the situation.
Bottom line--Don't go to the mediums and fortune tellers; but just go to God in prayer and read your Bible daily. Seek counsel from a pastor or Christian friend, and avoid those with "special powers."
Trust in the Lord with all your heart and lean not on your own understanding; in all your ways submit to him, and he will make your paths straight. Proverbs 3:5-6
