God’s people must have a thorough understanding of present truth, which we will be obliged to maintain from the Scriptures. We must understand the state of the dead; for the spirits of devils will yet appear to us, professing to be beloved relatives or friends, who will declare to us unscriptural doctrines.They will do all in their power to excite sympathy and will work miracles before us 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 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.
Satan assigns to each of his angels a part to act. He enjoins upon them all to be sly, artful, cunning. He instructs some of them to act the part of the dead and to speak for them….
Ecclesiastes 9:5 KJV For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten.
