Revelation 20 is one of the most misunderstood and debated passages of the whole Bible.  In American popular evangelicalism over the last century, the millennium is largely understood as a literal 1000 year reign of Christ in earth. Speculations of what this looks like and why it is needed abound! But there is another way to understand the millennium that the majority of the Church worldwide has accepted... that the millennium encompasses Christ's heavenly reign from heaven above for the whole period of time from His first coming until He returns... from advent to advent.
