Many deceivers have gone out into the world who do not confess Jesus Christ as coming in the flesh. This is a deceiver and an antichrist.--2 John 7
The rapping delusion was presented before me, and I saw that Satan has power to bring before us the appearance of forms purporting to be our relatives or friends who sleep in Jesus. It will be made to appear as if those friends were actually present, the words they uttered while here, with which we were familiar, will be spoken, and the same tone of voice that they had while living will fall upon the ear. All this is to deceive the world and ensnare them into the belief of this delusion.
I saw that the saints must have a thorough understanding of present truth, which they will be obliged to maintain from the Scriptures. They must understand the state of the dead; for the spirits of devils will yet appear to them, professing to be beloved relatives or friends, who will declare to them unscriptural doctrines. They will do all in their power to excite sympathy and will work miracles before them to confirm what they declare. The people of God must be prepared to withstand these spirits with the Bible truth that the dead know not anything, and that they who thus appear are the spirits of devils.
We must examine well the foundation of our hope; for we shall have to give a reason for it from the Scriptures. This delusion will spread, and we shall have to contend with it face to face; and unless we are prepared for it, we shall be ensnared and overcome. But if we do what we can on our part to be ready for the conflict that is just before us, God will do His part, and His all-powerful arm will protect us. He would sooner send every angel out of glory to make a hedge about faithful souls, than have them deceived and led away by the lying wonders of Satan. (Early Writings, 262)
REFLECTION: None need be deceived by the lying claims of spiritualism. God has given the world sufficient light to enable them to discover the snare. As already shown, the theory which forms the very foundation of spiritualism is at war with the plainest statements of Scripture. The Bible declares that the dead know not anything, that their thoughts have perished; they have no part in anything that is done under the sun; they know nothing of the joys or sorrows of those who were dearest to them on earth. (The Great Controversy, 556)
