John
clearly said the events were starting soon, in 4 different ways.
"near", "soon", he "Shared in their
tribulation" - and he wanted them to
obey his message.
That's NOT possible for THEM if we narcissistically assume it's all about US!
John wrote in a genre called apocalyptic symbolism which was common to 200 BC to about 200 AD.
Have you read any of the other works of the period? I've read snatches - years ago.
Enough to be convinced by those theologians that show it's a style that comments on the period the author lives in.
It's like dressing up the day's political events in the language of comic book heroes.
It's not a linear timeline of the future, it's a waltz around certain themes.
It's not a timeline, it's a circular thematic sermon.
And sermons often encourage us to consider the promised return of the Lord!
This does so by not just theologically asserting the promise of the Lord's return in judgement and salvation - as Paul might.
It does it by picturing it. But if you look closely - we see the Lord's return in judgement at a number of different points!
EG: In the end of Chapter 6, and multiple times, from multiple different points of view, at the end.
How can it be a timetable of the future if it's got Jesus returning at the end of Chapter 6, and multiple points at the end?
That doesn't make sense.
Anyone approaching it with today's trendy interpretive goggles of "What do me, myself, and I all think this means for the next decade?" is going to end up a bit...
