What does Revelation 20:9 mean?
In prior verses, Satan was bound for a thousand years prior to being released. The point of this release seems to be to prove an important point. Namely, that those who reject God do so out of stubbornness and pride—not a lack of information or evidence. Even after ten centuries of peace and righteousness, people will still choose to rebel against God.Satan's duped followers march to the camp of the saints, which is most likely Jerusalem. It is called "the beloved city" because God set His love there in a special way. When Jerusalem rejected Jesus during His first visit to earth, Jesus cried out to the city in a display of His love: "O Jerusalem, Jerusalem…How often would I have gathered your children together as a hen gathers her brood under her wings, and you were not willing" (Matthew 23:37). The fact that Jerusalem is the object of God's love might be sufficient reason for Satan's assault on her, but there is another reason. During the millennial reign of Christ, Jerusalem serves as His capital. Isaiah 2:2–3 prophesies that during the millennium all nations shall flow to the house of the Lord in Jerusalem and the Word of the Lord shall proceed from Jerusalem. The Devil's massive assault on Jerusalem fails, because fire comes down from heaven and consumes the assailants.
