Satan is seeking to deceive the church and the world. Let us then study the book of Revelation because it counters Satan's lies. Reference: E.G. White, "The Upward Look," p. 152

Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. Colossians 2:8.

At this time—the last days of this earth’s history—we are to make the book of Revelation a special study. Why? Because it depicts the scenes that we are to meet. We need to understand what we are to meet, and how we are to meet it. We must know what efforts we are to make, so that in this perilous time we shall not be taken by the enemy’s devices. We know that the last great conflict will be Satan’s most determined effort to accomplish his purposes. He will come, not only as a roaring lion, but as a seducer, clothing sin with beautiful garments of light that he may take human beings in his snare.

The Lord desires us to realize that it is of great importance that we stand in these last days upon the platform of eternal truth. Those who think that the church militant is the church triumphant make a great mistake. The church militant will gain great triumphs, but it will also have fierce conflicts with evil that it may be firmly established upon the platform of eternal truth. And every one of us should be determined to stand with the church upon this platform...

There are those today who call the Revelation a sealed book. [It is a mystery,] but it is a mystery unfolded. We need to understand what it tells us in regard to the scenes that are to take place in the last days of this earth’s history. The enemy will bring in everything that he possibly can to carry out his deceptive designs. Are they not lacking in wisdom who have no desire to understand in regard to the things that are to take place on this earth? ...

In a representation which passed before me, I saw a certain work being done by medical missionary workers. Our ministering brethren were looking on, watching what was being done, but they did not seem to understand. The foundation of our faith, which was established by so much prayer, such earnest searching of the Scriptures, was being taken down, pillar by pillar. Our faith was to have nothing to rest upon—the sanctuary was gone, the atonement was gone...

Do you wonder that I have something to say, when I see the pillars of our faith beginning to be moved? Seductive theories are being taught in such a way that we shall not recognize them unless we have clear spiritual discernment.—Manuscript 46, May 18, 1904, “The Foundation of Our Faith,” a talk given at Berrien Springs, Michigan.
