understand, Im not trying to slam dispies, even though they are wrong
however, as a simple starting definition of dispensationalim. They beileve essentially that since creation God has communed with man in
(1) Paradisaical state to the Flood
(2) Noah
(3) Abraham
(4) Israel
(5) Gentiles
(6) The Spirit
(7) The Millennium.
Now, the question would be. Why would the Almighty need 7? i dont know if im stretching to far, but it seems to me one possible mindset that may be needed is
"God tried this method, realized it wasn't working, so tried a different method"
