"Moreover Josiah put away the mediums and the wizards and the teraphim and the idols and all the abominations that were seen in the land of Judah and in Jerusalem, that he might establish the words of the law which were written in the book that Hilkiah the priest found int he house of the Lord. Before him there was no king like him, who turned to the Lord with all his heart and with all his soul and with all his might, according to all the law of Moses; nor did any like him arise after him." 2 Kings 23: 24-25
The law of Moses clearly names mediums, witches, wizards, soothsayers, seers and the like as abominations that shall not be tolerated by the people of God. Add to this dumb idols to false gods, and you've got a helluva mess. Do we not still play around with things like this. Telephone psychics and Harry Potter and the Ouija boards are but a few of the modern examples of things rooted someplace other than God. When we put our faith in false idols and dangerous spiritual concerns, we move away from the Truth; and we leave ourselves open to the beguiling temptations of the Prince of This World, Satan.
What happened to the Kingdom of Judah? In 587 B.C., the Babylonians came knocking on the front gate. When they left, their weren't two stones of the Temple of God left standing atop another.
