It's hard to have the events of Revelation 4-19 in the past when Revelation 1:19 and 4:1 clearly indicate these events start AFTER the church age. We are still in that period of time. Plus, you may as well throw out the whole book once you start abandoning the literal reading of the rest of the book - then you are just winging it and making it mean what you want it to mean - and there would be no objective way (beyond pure speculation) to determine when something was actually fulfilled.

That seven year time period has not occured yet, there is no one-world leader ruling, and there is no mark of the Beast instituted worldwide. When you abandon the plain sense of the passage, you abandon the whole book.
