Revelation 16:14 For they are the spirits of devils, working miracles, which go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.
[Patriarchs & Prophets pp 685] Many who reject spiritualism as the result of human skill or cunning will, when confronted with manifestations which they cannot account for upon this ground, be led to acknowledge its claims. Modern spiritualism and the forms of ancient witchcraft and idol worship—all having communion with the dead as their vital principle—are founded upon that first lie by which Satan beguiled Eve in Eden. “Ye shall not surely die: for God doth know that in the day ye eat thereof, ... ye shall be as gods.” Genesis 3:4, 5.
Alike based upon falsehood and perpetuating the same, they are alike from the father of lies. The Hebrews were expressly forbidden to engage in any manner in pretended communion with the dead. God closed this door effectually when He said: “The dead know not anything.... Neither have they any more a portion forever in anything that is done under the sun.” Ecclesiastes 9:5, 6. “His breath goeth forth, he returneth to his earth; in that very day his thoughts perish.” Psalm 146:4.
And the Lord declared to Israel: “The soul that turneth after such as have familiar spirits, and after wizards, to go a whoring after them, I will even set My face against that soul, and will cut him off from among his people.” Leviticus 20:6. The “familiar spirits” were not the spirits of the dead, but evil angels, the messengers of Satan.
Leviticus 19:31 Regard not them that have familiar spirits, neither seek after wizards, to be defiled by them: I am the Lord your God.
May God add His blessing to the study of His word. “Good night” and God bless!
