“To the law and to the testimony: if they speak not according to this word, it is because there is no light in them” (Isaiah 8:20). The people of God are directed to the Scriptures as their safeguard against the influence of false teachers and the delusive power of spirits of darkness. Satan employs every possible device to prevent men from obtaining a knowledge of the Bible; for its plain utterances reveal his deceptions. At every revival of God's work the prince of evil is aroused to more intense activity; he is now putting forth his utmost efforts for a final struggle against Christ and His followers. The last great delusion is soon to open before us. Antichrist is to perform his marvelous works in our sight. So closely will the counterfeit resemble the true that it will be impossible to distinguish between them except by the Holy Scriptures. By their testimony every statement and every miracle must be tested.—The Great Controversy, 593. TR 54.1
