The doctrine of natural immortality has prepared the way for modern Spiritualism. If the dead are admitted to the presence of God and holy angels, and privileged with knowledge far exceeding what they before possessed, why should they not return to the earth to enlighten and instruct the living? How can those who believe in man's consciousness in death reject what comes to them as divine light communicated by glorified spirits? Here is a channel regarded as sacred, through which Satan works for the accomplishment of his purposes. The fallen angels who do his bidding appear as messengers from the spirit world. While professing to bring the living into communication with the dead, Satan exercises his bewitching influence upon their minds. SR 393.1
He has power even to bring before men the appearance of their departed friends. The counterfeit is perfect; the familiar look, the words, the tone, are reproduced with marvelous distinctness. Many are comforted with the assurance that their loved ones are enjoying the bliss of heaven, and without suspicion of danger they give ear to seducing spirits and doctrines of devils. SR 393.2
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 which 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 divinity of Christ and place even the Creator on a level with themselves. Thus under a new disguise the great rebel still carries forward his warfare against God, begun in heaven and for nearly six thousand years continued upon the earth. SR 393.3
Many endeavor to account for spiritual manifestations by attributing them wholly to fraud and sleight of hand on the part of the medium. While it is true that the results of trickery have often been palmed off as genuine manifestations, there have been, also, marked exhibitions of supernatural power. The mysterious rapping with which modern Spiritualism began was not the result of human trickery or cunning, but the direct work of evil angels, who thus introduced one of the most successful of soul-destroying delusions. Many will be ensnared through the belief that Spiritualism is a merely human imposture; when brought face to face with manifestations which they can but regard as supernatural, they will be deceived, and will be led to accept them as the great power of God.

These persons overlook the testimony of the Scriptures concerning the wonders wrought by Satan and his agents. It was by Satanic aid that Pharaoh's magicians were enabled to counterfeit the work of God. The apostle John, describing the miracle-working power that will be manifested in the last days, declares: “He doeth great wonders, so that he maketh fire come down from heaven on the earth in the sight of men, and deceiveth them that dwell on the earth by the means of those miracles which he had power to do.” Revelation 13:13, 14. No mere impostures are here brought to view. Men are deceived by the miracles which Satan's agents have power to do, not which they pretend to do. SR 395.1
