The bible lets us know the following about the occult;
The power of the occult is real
The force behind it is Satan
The effects on those who are involved with it usually end in disaster
It is forbidden for God’s people
9When you enter the land the LORD your God is giving you, do not learn to imitate the detestable ways of the nations there. 10Let no one be found among you who sacrifices his son or daughter in the fire, who practices divination or sorcery, interprets omens, engages in witchcraft, 11or casts spells, or who is a medium or spiritist or who consults the dead. 12Anyone who does these things is detestable to the LORD, and because of these detestable practices the LORD your God will drive out those nations before you. 13You must be blameless before the LORD your God.
14The nations you will dispossess listen to those who practice sorcery or divination. But as for you, the LORD your God has not permitted you to do so.
Deuteronomy 18:9-14 (NIV)
God therefore does not want His people to be involved in the occult which includes seances.
