Bible chronology indicates that this battle, cleansing the heavens of Satan and his demons, would result in great woe for the earth because of the Devil’s anger at knowing that his time left for ruling the earth was short. His anger would increase during the last days until his total defeat at the war of Armageddon.—Revelation 16:14, 16; 19:11, 15; 20:1-3.

Some of the events yet to come are the “great tribulation,” including the war of Armageddon, and the restricting of Satan and his demons so that they cannot affect the earth. (Matthew 24:21) “God, who cannot lie,” has assured us that these things will take place. (Titus 1:2) Armageddon and the abyssing of Satan will be the result of divine intervention.
