“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.” [Great Controversy p. 497 chap. 29 by Ellen G. White]
