Leaving his place in God's presence, Lucifer went out to spread discontent among the angels. With mysterious secrecy, hiding his real purpose under an appearance of reverence for God, he tried to make the angels dissatisfied with the laws that governed heavenly beings. He suggested that these laws were unnecessary and held them back. Since their natures were holy, he urged that angels should follow their own wills. He held that God had dealt unfairly with him by giving supreme honor to Christ. He claimed he was not trying to exalt himself but was seeking to win liberty for every being in heaven, so that each one could reach a higher level of existence. LF 204.3
God was patient with Lucifer. He did not remove him from his honored position even when he began to make false claims to the angels. Again and again God offered him pardon if he would repent and submit. God made efforts that only infinite love could devise to convince him of his error. Discontent had never before been known in heaven. At first, Lucifer himself did not understand the real nature of his feelings. As God showed that there was no reason for his dissatisfaction, Lucifer was convinced that the divine claims were right and that he ought to acknowledge them to all heaven. If he had done this, he would have saved himself and many angels. If he had been willing to return to God, satisfied to fill the place God had given him, God would have reinstated him to his position. But pride would not let him submit. He claimed that he did not need to repent, and he fully committed himself to the great controversy against his Maker. LF 204.4
He now applied all the powers of his master mind to deception, to gain the sympathy of the angels. Satan claimed that God had judged him wrongly and had restricted his liberty. After misrepresenting Christ's words he moved on to telling actual lies, accusing the Son of God of plotting to humiliate him before the inhabitants of heaven. LF 205.1
All whom he could not win to his side he accused of being indifferent to the concerns of heavenly beings. He resorted to misrepresenting the Creator. He tried to perplex the angels with subtle arguments about God's plans. Everything simple he shrouded in mystery, and by clever perversion he made the plainest statements of God appear doubtful. His high position gave greater credibility to his claims. He persuaded many to join him in rebellion. LF 205.2
