Garry,
    You said a lot of great, meaty stuff.
It was a real good look at the 7 seals.
I agree with you about them not being 100% world-wide destruction, but localized.
Clearly, the description of Babylon, in Revelation 18, shows that she lives deliciously all the way up to chapter 19.
That is while the seals, trumpets, and vials are affecting other peoples in other places.
