God does not consider sorcery or witchcraft to be innocent fun for children or adults. He confronts it in the strongest of terms. So, let s take a moment to examine how seriously God views this sin. There shall not be found among you anyone who makes his son or his daughter pass through the fire, or one who practices witchcraft, or a soothsayer, or one who interprets omens, or a sorcerer, or one who conjures spells, or a medium, or a spiritist, or one who calls up the dead. For all who do these things are an abomination to the Lord, and because of these abominations the Lord your God drives them out before you.
Scripture also points out that nothing good can come out of trying to communicate with the dead.
If someone believes they are speaking to the dead, then it is something to be feared, not embraced. Demons will gladly disguise themselves as the dead, if it will gain them an audience. Centuries ago, Jesus predicted there would come a day when many would reject God s truth and accept the counterfeit gospel of Satan. Blindly following an ingenious counterfeit, many will stumble headlong into evil, unaware they are being deceived. Sadly, many will never stop to heed the warnings that foretell of the deception and will allow themselves to be hardened to the truth.
