We have Saul's example with contacting Samuel. The Lord has been very clear that it's forbidden. He has impressed this strongly on me. There is no righteous way to use the enemy's tools. Most of it is straight "horoscope" though regardless.
The Lord has his own insight to give...
I agree. I believe it's enslaving and bad things can come up as a result. I have come to believe that we come under power of things we put trust into and become their subject, it's opposite of the work Jesus did over our lives, freeing us from powers and principalities. Do we really want to have events in our lives subject to and ruled by these powers? Typically when they do readings, tarot or anything. they prognosticate nice things to bait people. I think people potentially also give these things permission to affect their life by accepting to be entertained. So also listening to these people and letting ears be tickled may work as a form of agreement. And the fortune teller typically does guess something amazing the first time. But later bad things may happen and previous good taken away. Husband knew a man whose life was wrecked by trusting in tarot, had nice things happen first, then all he had went down.
