Ezekiel 28:14 Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire. 15 Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.
[Patriarchs & Prophets pp 37] As songs of praise ascended in melodious strains, swelled by thousands of glad voices, the spirit of evil seemed vanquished; unutterable love thrilled his entire being; his soul went out, in harmony with the sinless worshipers, in love to the Father and the Son. But again he was filled with pride in his own glory. His desire for supremacy returned, and envy of Christ was once more indulged. The high honors conferred upon Lucifer were not appreciated as God's special gift, and therefore, called forth no gratitude to his Creator. He gloried in his brightness and exaltation and aspired to be equal with God.
He was beloved and reverenced by the heavenly host, angels delighted to execute his commands, and he was clothed with wisdom and glory above them all. Yet the Son of God was exalted above him, as one in power and authority with the Father. He shared the Father's counsels, while Lucifer did not thus enter into the purposes of God. “Why,” questioned this mighty angel, “should Christ have the supremacy? Why is He honored above Lucifer?” Leaving his place in the immediate presence of the Father, Lucifer went forth to diffuse the spirit of discontent among the angels.
He worked with mysterious secrecy, and for a time concealed his real purpose under an appearance of reverence for God. He began to insinuate doubts concerning the laws that governed heavenly beings, intimating that though laws might be necessary for the inhabitants of the worlds, angels, being more exalted, needed no such restraint, for their own wisdom was a sufficient guide. They were not beings that could bring dishonor to God; all their thoughts were holy; it was no more possible for them than for God Himself to err.
John 8:44 He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
May The Lord add His blessing to the study of His word. God bless!
