I need to sit on the porch with you for a few days.. :)
I see the same thing, roughly... The thing that lead me out of dispensationalism (which I do agree with in part) is the idea that the Prophecy stopped cold-stone dead for more than two thousand years. When one understands that it's been ticking right along like the best of Swiss watches opens one to discover all that has gone unnoticed during all the centuries of replacement theology.
Interesting perspective with regards to how replacement theology has stifled for centuries a clear literal look at prophecy. It makes things quite easy, and incorrect to “insert church here where Israel is mentioned.”
ES, for the first five seals to be a gradual historical march since Chirst Sat at the Right Hand of The Father, would that not mean 3.5 “days” of the 7th week was spread over the centuries?
