Too many Hollywood OMEN movies have coloured the way Americans read Revelation. I'm Sydney Anglican, which means we see it as a symbolic sermon reminding us of our gospel hope. Which means we are "Amil" or A-millennial - no literal millennium. It's a symbolic sermon, not a timeline. It's about how to hold up under 4 scary themes we see cycle through our world over the centuries again and again - with a reminder of the gospel hope that at the end the Lord will fix it all.
As Sydney Anglican Bishop (with Phd's in theology and history) Paul Barnett explains, the 1000 years actually describes Jesus reign during the period we are in right now. The period between Jesus resurrection and return. The bad stuff we see in the world both now and the last 2000 years.
Let's check out the structure. They're to be read along side each other - not to be read sequentially like some sort of future timeline.
HUMAN HISTORY: THE 1000 YEARS:-
Seven seals depicting TYRANNY (then back to the beginning to describe)...
Seven trumpets depicting CHAOS in nature (then back to the beginning to describe)...
Seven signs depicting PERSECUTION (then back to the beginning to describe)...
Seven plagues depicting DESTRUCTION.
These episodes are concurrent, not consecutive.
Wouldn't it be ironic if we were looking for how the CoronaVirus pandemic fit into some future timeline and missed it entirely because we were looking for a timeline prediction rather than a thematic description? What if we missed the entire point of Revelation, and missed biblical warnings and encouragements about our lives now - and the last 2000 years - because we were trying to read it with the wrong glasses on? Try Paul Barnett's book.

Bottom line - it describes natural disasters, tyrants persecuting the church, 'beast-states', the temptations of trusting in materialism and luxury and even state security, and all manner of other things the human race have experienced over the last 2000 years and into the next. Revelation was a book John wrote about impending Roman persecution, but also other themes. Some images (like the beast) describe Roman stuff, other things are more generic. Not everything has to be fulfilled in the first century because it was a general description of life and the various temptations we'll face.
Or another example - while Rev 13 describes Rome's persecution of the Christians in Asia Minor, it also tells us
general principles about beast states that persecute the church. Hitler was one beast state, Stalin another, North Korea yet another. There are many examples - but Amil Christians that live in persecution look to Revelation as a source of comfort. Yes, being persecuted is bad. But to the Christians that suffer with patient endurance and hope, there is the gospel hope that Jesus will return and raise and reward them. They laugh at the idea that John would have told
his own generation of suffering Christians "You think you've got it bad under the Romans, wait till you see what happens in 2000 years!" That's the difference between seeing a thematic sermon and a future timeline. A sermon is relevant for all Christians across all time. A timetable is only relevant to those Christians willing to play endless guessing games about the last few years of history. To which I ask - what on earth has been the whole point of the book for the last 2000 years? Honestly!?
