Read Matthew 24:5, 11, 24; 2 Thessalonians 2:7-9; Revelation 13:13, 14; and Revelation 16:13, 14. What kind of deceptions will people face in the last days?

 The devil will use “signs and wonders” and spectacular miracles to deceive multitudes just before the coming of Jesus. Commenting on the deceptive power of demonic spirits, Ángel Rodríguez makes this telling statement: “Their power of persuasion is to be found not in the content of their message but in the power of supernatural manifestations called ‘signs’ or ‘miracles.’ They perform/do (poieō) signs, thus appealing to the affective side of human beings rather than to their discretionary and rational abilities. The fact that these signs are performed by demons shows that the unifying force of the message of the three demons [dragon, beast, and false prophet] is spiritualistic in nature—God is not their source or origin. As the cosmic conflict approaches its closure, demonic power will enter the arena of human history in an unprecedented way. Spiritualism, whose very foundation is the non-biblical teaching of the immortality of the soul, will nearly take the world captive.”—“The Closing of the Cosmic Conflict: Role of the Three Angels’ Messages,” unpublished manuscript, p. 6.

 Why is it dangerous to trust our emotions? What roles do they play, good and bad, in our faith experience? How might Satan bypass our thinking processes and appeal to our feelings?

 “Satan has long been preparing for his final effort to deceive the world. . . . Little by little he has prepared the way for his masterpiece of deception in the development of spiritualism. He has not yet reached the full accomplishment of his designs; but it will be reached in the last remnant of time. . . . Except those who are kept by the power of God, through faith in His word, the whole world will be swept into the ranks of this delusion. The people are fast being lulled to a fatal security, to be awakened only by the outpouring of the wrath of God.”—Ellen G. White, The Great Controversy,pp. 561, 562.

 Our sole security is in Jesus and His Word. It’s not hard to see how millions, even billions, who do not understand the state of the dead could be swept away by delusions involving the idea that the dead live on after death.
