A more sure word of prophecy

In heaven itself this law was broken. 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. Thus he deceived angels. Thus he deceived men. He led them to doubt the word of God, and to distrust His goodness. Because God is a God of justice and terrible majesty, Satan caused them to look upon Him as severe and unforgiving. Thus he drew men to join him in rebellion against God, and the night of woe settled down upon the world. DA 21.3
