Ouija Boards, Warfare, Exorcism, and the Bible’s Undeniable Stance on Playing with Fire
We are advised not to “practice divination or seek omens” (Leviticus 19:26), not to “turn to mediums or seek out spiritists” (Leviticus 19:31), and not to consult the dead.
And those cautionary verses are overtly stern, warning that humans will be defiled by such practices. Despite these biblical claims, culture encourages, facilitates, and praises these attempts to communicate with the dead, using the Ouija board — a “game” people often play at slumber parties and other gatherings. The Ouija board is a pop culture staple.
For many, the idea of a legitimate psychic reading might seem ridiculous or impractical, a grand scheme to sucker people out of their money — and that’s understandable.
Do not turn to mediums or seek out spiritists, for you will be defiled by them. I am the Lord your God.
When you enter the land the Lord your God is giving you, do not learn to imitate the detestable ways of the nations there. Let no one be found among you who sacrifices their son or daughter in the fire, who practices divination or sorcery, interprets omens, engages in witchcraft, or casts spells, or who is a medium or spiritist or who consults the dead. Anyone who does these things is detestable to the Lord; because of these same detestable practices, the Lord your God will drive out those nations before you. You must be blameless before the Lord your God.
In discussing this issue, the prophet pondered why people wouldn’t simply turn to God: "Why consult the dead on behalf of the living?”
And to showcase just how seriously this was all taken, Leviticus 20:27 prescribed a serious penalty for such activities: “A man or woman who is a medium or spiritist among you must be put to death. You are to stone them; their blood will be on their own heads.”
how do we protect ourselvesagainst the flames of spiritual fires? Paul provided the answer when he reminded believers to “put on the full armor of God” so that each person can "stand against the devil’s schemes” (Ephesians 6:10-12
The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel that displays the glory of Christ, who is the image of God. — 2 Corinthians 4:4
