When they have been led to believe that the dead actually return to communicate with them, Satan causes those to appear who went into the grave unprepared. They claim to be happy in heaven and even to occupy exalted positions there, and thus the error is widely taught that no difference is made between the righteous and the wicked. The pretended visitants from the world of spirits sometimes utter cautions and warnings which prove to be correct. Then, as confidence is gained, they present doctrines that directly undermine faith in the Scriptures. With an appearance of deep interest in the well-being of their friends on earth, they insinuate the most dangerous errors. The fact that they state some truths, and are able at times to foretell future events, gives to their statements an appearance of reliability; and their false teachings are accepted by the multitudes as readily, and believed as implicitly, as if they were the most sacred truths of the Bible. The law of God is set aside, the Spirit of grace despised, the blood of the covenant counted an unholy thing. The spirits deny the deity of Christ and place even the Creator on a level with themselves. Thus under a new disguise the great rebel still carries on his warfare against God, begun in heaven and for nearly six thousand years continued upon the earth. DD 19.2
