This remarkable scene in heaven provides us a striking picture of Satanic activity. The devil, in his opposition to God and His program of salvation, evidently never rests. He is not omnipresent, like God, because he is a finite (though very powerful and brilliant) created being. To accomplish his goal, therefore, he is never at rest, but keeps going from place to place and working deception after deception, bringing everyone he can under his influence.
Therefore, God urgently warns us: "Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour" (1 Peter 5:8).
The same is true of the demonic spirits who have followed the devil in his rebellion against God. They never rest until they can take possession of some person's body and mind and then control that person's behavior. "When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest, and findeth none. Then he saith, I will return into my house from whence I came out" (Matthew 12:43-44).
This restlessness that characterizes the devil and his demons often also manifests itself in the unsaved, and this will be the ultimate state of those who yield to the pressures of these evil spirits. "They have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name" (Revelation 14:11).
True rest of soul is found only in Christ, with His forgiveness and cleansing and guidance. "Come unto me, all ye that labour and are heavy laden," Jesus says, "and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls" (Matthew 11:28-29). HMM
