12-14 (see EGW comment on Ezekiel 28:13-15). Satan′s Rebellion of Long Standing—The records of some are similar to that of the exalted angel who was given a position next to Jesus Christ in the heavenly courts. Lucifer was enshrouded with glory as the covering cherub. Yet this angel whom God had created, and entrusted with power, became desirous of being as God. He gained the sympathy of some of his associates by suggesting thoughts of criticism regarding the government of God. This evil seed was scattered in a most seducing manner; and after it had sprung up and taken root in the minds of many, he gathered the ideas that he himself had first implanted in the minds of others, and brought them before the highest order of angels as the thoughts of other minds against the government of God. Thus, by ingenious methods of his own devising, Lucifer introduced rebellion in heaven.
(4BC 1143.1)
God desired that a change take place, and that the work of Satan be brought out in its genuine aspect. But the exalted angel standing next to Christ was opposed to the Son of God. The underworking was so subtle that it could not be made to appear before the heavenly host as the thing that it really was; and so there was war in heaven, and Satan was expelled with all who would not stand on the side of loyalty to God′s government. The Lord God stood forth as Supreme Ruler.
(4BC 1143.2)
This condition of things had existed a long period of time before Satan was unmasked and the evil ones expelled (Letter 162, 1906).
