My first objection is that taking it chronologically inherently helps Pre-Trib, Pre-Trib sees The Rapture not in Revelation at all so really it's chronology should be irrelevant to them. I see it clearly in the middle of the book, from the latter part of Chapter 11 through chapter 14, with the key moment being The Rapture of the Man-Child.
1), His intent was clearly to try as much as possible to write things down as he saw them.
2), Certain subjects RE clearly scattered about, the book is clearly not organized by subject, even The Beast gets a reference before his formal introduction.
3), This I assume is mainly about the mystery of the Seven heads, and maybe the various time statements.
The reason Revelation's Authorship confuses people is indeed because it was really written by Jesus with John as his stenographer. It's actually wrong to say Jesus wrote none of The Bible.
Since Jack Kelly knows John's Gospel is the least Chronological, I wonder if he is wiling to admit Jesus ministry wasn't three years but only one tops.
