What does Revelation 12:12 mean?
The voice from heaven that John heard called on all of creation to rejoice. The Devil's defeat and banishment from heaven was an occasion of great joy. However, the voice also pronounced woe to the earth and sea because the Devil was confined to the earth. Further, the Devil knew his time was short. Soon he would be confined to the bottomless pit and then to the lake of fire. So he will try to do as much damage as he can in the brief time that he has left.Specifically, at this point in time, Satan knows he only has 1,260 days, the second half of the tribulation, to vent his fury. Although Satan is not omniscient—all knowing—he knows the Scriptures. He used them in a futile attempt to trip Jesus and cause Him to sin. He knows the Scripture foretells his appointment with eternal judgment. But how will he vent his fury in the second half of the tribulation? Revelation 12:13–17 and Revelation 13:1–18 give the answer.
