In tthe Bible things like witchcraft, sorcery, mediums, soothsayers, and the alike are all an abominations in the eyes of God. Things like this tend to lead people astray from the one true Mediator and they get lost in devistating practices. There is no need to consult the dead for something God can give you. Just keep in mind that in the Holy Bible in the book of Deuteronomy Chapter 18 verses 10-12 it says," There shall not be found among you anyone who makes his son or 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 call up the dead. " For all who do these things are an abomination to the Lord, and because of these abominations God drives them out from before you.
