I would take issue with using only a backed out farscape long count perspective and not allowing for a more precise one to fit into the seven years of Daniel's seventieth week. In any event, I believe the Word of God clearly shows the born agains are snatched away before the man of sin / lawlessness can even be revealed.
I think John’s revelations occurred at various times and may not be in any kind of chronological order, except for the chapters to the churches coming first. He didn’t understand them totally at the time, so he couldn’t put them in strict order? I believe I did read this at one time, although I am far from a biblical scholar.
