God in His wisdom permitted Satan to carry forward his work, until the spirit of disaffection ripened into active revolt. It was necessary for his plans to be fully developed, that their true nature and tendency might be seen by all. Lucifer, as the anointed cherub, had been highly exalted; he was greatly loved by the heavenly beings, and his influence over them was strong. God’s government included not only the inhabitants of heaven, but of all the worlds that He had created; and Satan thought that if he could carry the angels of heaven with him in rebellion, he could carry also the other worlds. He had artfully presented his side of the question, employing sophistry and fraud to secure his objects. His power to deceive was very great, and by disguising himself in a cloak of falsehood he had gained an advantage. Even the loyal angels could not fully discern his character or see to what his work was leading. (GC 497.1) MC VC

Satan had been so highly honored, and all his acts were so clothed with mystery, that it was difficult to disclose to the angels the true nature of his work. Until fully developed, sin would not appear the evil thing it was. Heretofore it had had no place in the universe of God, and holy beings had no conception of its nature and malignity. They could not discern the terrible consequences that would result from setting aside the divine law. Satan had, at first, concealed his work under a specious profession of loyalty to God. He claimed to be seeking to promote the honor of God, the stability of His government, and the good of all the inhabitants of heaven. While instilling discontent into the minds of the angels under him, he had artfully made it appear that he was seeking to remove dissatisfaction. When he urged that changes be made in the order and laws of God’s government, it was under the pretense that these were necessary in order to preserve harmony in heaven. (GC 497.2) MC VC
