Revelation 12:9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceives the whole world: he was cast out into the earth, and his angels were cast out with him.
[Patriarchs & Prophets pp 52] No longer free to stir up rebellion in heaven, Satan's enmity against God found a new field in plotting the ruin of the human race. In the happiness and peace of the holy pair in Eden he beheld a vision of the bliss that to him was forever lost. Moved by envy, he determined to incite them to disobedience, and bring upon them the guilt and penalty of sin. He would change their love to distrust and their songs of praise to reproaches against their Maker.
Thus he would not only plunge these innocent beings into the same misery which he was himself enduring, but would cast dishonor upon God, and cause grief in heaven. Our first parents were not left without a warning of the danger that threatened them. Heavenly messengers opened to them the history of Satan's fall and his plots for their destruction, unfolding more fully the nature of the divine government, which the prince of evil was trying to overthrow.
It was by disobedience to the just commands of God that Satan and his host had fallen. How important, then, that Adam and Eve should honor that law by which alone it was possible for order and equity to be maintained. The law of God is as sacred as God Himself. It is a revelation of His will, a transcript of His character, the expression of divine love and wisdom. The harmony of creation depends upon the perfect conformity of all beings, of everything, animate and inanimate, to the law of the Creator.
Revelation 12:10 And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.
May God add His blessing to the study of His word. “Good night” and God bless!
