Satan Diverts Minds by Controversial Subjects—He [the enemy] would be delighted to have minds diverted to any subject by which he might create division of sentiment and lead our people into controversy.— Manuscript 167, 1897. (1MCP 23.1) MC VC

One Mind Dominating Another—Satan often finds a powerful agency for evil in the power which one human mind is capable of exerting on another human mind. This influence is so seductive that the person who is being molded by it is often unconscious of its power. God has bidden me speak warning against this evil.— Letter 244, 1907 (Selected Messages 2:352.) (1MCP 23.2) MC VC

A Power for Good, a Power for Evil—The influence of mind on mind, so strong a power for good when sanctified, is equally strong for evil in the hands of those opposed to God. This power Satan used in his work of instilling evil into the minds of the angels, and he made it appear that he was seeking the good of the universe. As the anointed cherub, Lucifer had been highly exalted; he was greatly loved by the heavenly beings, and his influence over them was strong. Many of them listened to his suggestions and believed his words. “And there was war in heaven: Michael and His angels fought against the dragon; and the dragon fought and his angels, and prevailed not; neither was their place found any more in heaven” (Revelation 12:8).— Letter 114, 1903 (The S.D.A. Bible Commentary 7:973.) (1MCP 23.3) MC VC

One Man’s Mind Not to Be Trusted—One man’s mind and one man’s judgment was not to be trusted, for too great interests were at stake, and it was not free from human frailties and human errors.... There is not any one man’s mind so perfect that there is no danger of his moving from wrong motives, viewing things from a wrong standpoint.— Letter 41, 1891 (1MCP 23.4) MC VC

Each Must Choose One of Two Banners—Here is the great issue. Here are the two great powers confronting each other, the Prince of God, Jesus Christ, and the prince of darkness, Satan. Here comes the open conflict. There are but two classes in the world, and every human being will range under one of the two banners, the banner of the prince of darkness or the banner of Jesus Christ.— Letter 38, 1894 (1MCP 29.2) MC VC
