He has power 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.” (GC 552.1) MC VC

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. (GC 552.2) MC VC

Many endeavor to account for spiritual manifestations by attributing them wholly to fraud and sleight of hand on the part of the medium. But 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 was 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 cannot 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. Paul testifies that before the second advent of Christ there will be similar manifestations of satanic power. The coming of the Lord is to be preceded by “the working of Satan with all power and signs and lying wonders, and with all deceivableness of unrighteousness.” 2 Thessalonians 2:9, 10. And 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 foretold. Men are deceived by the miracles which Satan’s agents have power to do, not which they pretend to do. (GC 553.2) MC VC

The prince of darkness, who has so long bent the powers of his mastermind to the work of deception, skillfully adapts his temptations to men of all classes and conditions. To persons of culture and refinement he presents spiritualism in its more refined and intellectual aspects, and thus succeeds in drawing many into his snare. The wisdom which spiritualism imparts is that described by the apostle James, which “descendeth not from above, but is earthly, sensual, devilish.” James 3:15. This, however, the great deceiver conceals when concealment will best suit his purpose. He who could appear clothed with the brightness of the heavenly seraphs before Christ in the wilderness of temptation, comes to men in the most attractive manner as an angel of light. He appeals to the reason by the presentation of elevating themes; he delights the fancy with enrapturing scenes; and he enlists the affections by his eloquent portrayals of love and charity. He excites the imagination to lofty flights, leading men to take so great pride in their own wisdom that in their hearts they despise the Eternal One. That mighty being who could take the world’s Redeemer to an exceedingly high mountain and bring before Him all the kingdoms of the earth and the glory of them, will present his temptations to men in a manner to pervert the senses of all who are not shielded by divine power.

Many will be confronted by the spirits of devils personating beloved relatives or friends and declaring the most dangerous heresies. These visitants will appeal to our tenderest sympathies and will work miracles to sustain their pretensions. We must be prepared to withstand them with the Bible truth that the dead know not anything and that they who thus appear are the spirits of devils. (GC 560.1) MC VC

Just before us is “the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.” Revelation 3:10. All whose faith is not firmly established upon the word of God will be deceived and overcome. Satan “works with all deceivableness of unrighteousness” to gain control of the children of men, and his deceptions will continually increase. But he can gain his object only as men voluntarily yield to his temptations. Those who are earnestly seeking a knowledge of the truth and are striving to purify their souls through obedience, thus doing what they can to prepare for the conflict, will find, in the God of truth, a sure defense. “Because thou hast kept the word of My patience, I also will keep thee” (verse 10), is the Saviour’s promise. He would sooner send every angel out of heaven to protect His people than leave one soul that trusts in Him to be overcome by Satan. (GC 560.2) MC VC

The prophet Isaiah brings to view the fearful deception which will come upon the wicked, causing them to count themselves secure from the judgments of God: “We have made a covenant with death, and with hell are we at agreement; when the overflowing scourge shall pass through, it shall not come unto us: for we have made lies our refuge, and under falsehood have we hid ourselves.” Isaiah 28:15. In the class here described are included those who in their stubborn impenitence comfort themselves with the assurance that there is to be no punishment for the sinner; that all mankind, it matters not how corrupt, are to be exalted to heaven, to become as the angels of God. But still more emphatically are those making a covenant with death and an agreement with hell, who renounce the truths which Heaven has provided as a defense for the righteous in the day of trouble, and accept the refuge of lies offered by Satan in its stead—the delusive pretensions of spiritualism.
