Q. Is there anywhere in scripture that says Daniel’s 70th week will begin immediately following the Rapture, or could, say 5 or 10 years go by after the Rapture but before the beginning of the 70th week?
A. As we progress toward the End of the Age a pre-determined agenda of events have to unfold in an ever shorter period of time. If you believe, as I do, that in Matt. 24:34 Jesus told us the generation of people being born at the time Israel was re-born would still be alive when He returns, and that in Psalm 90:10 Moses said an average lifespan would be 70-80 years (as it is today) then you can conclude that the 2nd Coming is near. Using 1948 as Israel’s birth date and the outer limit of Psalm 90:10 puts it sometime around 2028. Subtracting 7 years for Daniel’s 70th Week would bring us to 2021.
I believe the rapture can literally happen any day now. If it happens today (please, God) there would be 8 years before the beginning of Daniel’s 70th week. All this is hypothetical of course, but demonstrates that the world is quite probably running out of time.
