Revelation 12:7 And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels, 8 And prevailed not; neither was their place found any more in heaven. 9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
[The Desire Of Ages. pp 761>762] Yet Satan was not then destroyed. The angels did not even then understand all that was involved in the great controversy. The principles at stake were to be more fully revealed. And for the sake of man, Satan's existence must be continued. Man as well as angels must see the contrast between the Prince of light and the prince of darkness. He must choose whom he will serve. In the opening of the great controversy, Satan had declared that the law of God could not be obeyed, that justice was inconsistent with mercy, and that, should the law be broken, it would be impossible for the sinner to be pardoned.
Every sin must meet its punishment, urged Satan; and if God should remit the punishment of sin, He would not be a God of truth and justice. When men broke the law of God, and defied His will, Satan exulted. It was proved, he declared, that the law could not be obeyed; man could not be forgiven. Because he, after his rebellion, had been banished from heaven, Satan claimed that the human race must be forever shut out from God's favor. God could not be just, he urged, and yet show mercy to the sinner. But even as a sinner, man was in a different position from that of Satan. Lucifer in heaven had sinned in the light of God's glory. To him as to no other created being was given a revelation of God's love.
Understanding the character of God, knowing His goodness, Satan chose to follow his own selfish, independent will. This choice was final. There was no more that God could do to save him. But man was deceived; his mind was darkened by Satan's sophistry. The height and depth of the love of God he did not know. For him there was hope in a knowledge of God's love. By beholding His character he might be drawn back to God. Through Jesus, God's mercy was manifested to men; but mercy does not set aside justice. The law reveals the attributes of God's character, and not a jot or tittle of it could be changed to meet man in his fallen condition.
Psalms 85:9 Surely his salvation is nigh them that fear him; that glory may dwell in our land. 10 Mercy and truth are met together; righteousness and peace have kissed each other.
May God add His blessing to the study of His word. "Good night" and God bless!
