The earth was dark through misapprehension of God. That the gloomy shadows might be lightened, that the world might be brought back to God, Satan’s deceptive power was to be broken. This could not be done by force. The exercise of force is contrary to the principles of God’s government; He desires only the service of love; and love cannot be commanded; it cannot be won by force or authority. Only by love is love awakened. To know God is to love Him; His character must be manifested in contrast to the character of Satan. This work only one Being in all the universe could do. Only He who knew the height and depth of the love of God could make it known. Upon the world’s dark night the Sun of Righteousness must rise, “with healing in His wings.”  – DA 22.1 

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
