Sin and the First Rebel
Pride goeth before destruction, and an haughty spirit before a fall. Proverbs 16:18.
Satan fell because of his ambition to be equal with God. He desired to enter into the divine counsels and purposes, from which he was excluded by his own inability, as a created being, to comprehend the wisdom of the Infinite One. It was this ambitious pride that led to his rebellion, and by the same means he seeks to cause the ruin of man.8Testimonies for the Church 5:702.
Sin originated in self-seeking. Lucifer, the covering cherub, desired to be first in heaven. He sought to gain control of heavenly beings, to draw them away from their Creator, and to win their homage to himself. Therefore he misrepresented God, attributing to Him the desire for self-exaltation. With his own evil characteristics he sought to invest the loving Creator.9The Desire of Ages, 21, 22.
Had Lucifer really desired to be like the Most High, he would never have deserted his appointed place in heaven; for the spirit of the Most High is manifested in unselfish ministry. Lucifer desired God's power, but not His character. He sought for himself the highest place, and every being who is actuated by his spirit will do the same.10The Desire of Ages, 435, 436.
