Revelation 20 comes in the middle of the final set of visions that complete the book of Revelation. The first part of chapter 19 shows the great celebration of the Lamb’s marriage following the fall of Babylon the Great in chapter 18. Then comes the battle that’s not really a battle where the rider on the white horse (Jesus, crucified and resurrected) captures two of his main enemies, the Beast and the False Prophet, and dispatches them (without an actual battle) to the lake of fire.
The book concludes in chapters 21 and 22 with a vision of the New Jerusalem, the city of genuine peace and healing that has been in the background from the beginning of Revelation. Tears are wiped away never to return, and ceaseless celebration and praise of the Lamb and the One on the throne ensues.
In between, in chapter 20, come a series of difficult to understand visions that complete the judgment and destruction of the powers of evil (here the Dragon, the power behind Babylon, the Beast, and the False Prophet) and that portray the judgment of all of humanity and the final destruction of Death and Hades.
I will suggest that these visions (along with the rest of Revelation, actually) should not be read strictly in terms of chronology. One of the interpretive approaches that especially makes the visions in chapter 20 confusing is to assume that this chapter presents events that will happen in the future after everything else that we have seen—rather than seeing this chapter as a kind of recapitulation of some of the main themes from earlier in the book. That is, Revelation 20 is also best understood as a picture of present reality. And it presents a theology of judgment that is actually quite different that what is usually assumed to be characteristic of Revelation.
