We agree pretty much on this point. ^
Jesus spoke of it throughout His entire earthly ministry (first advent)... every time that He spoke of:
--"the kingdom OF THE heavenS"
--"the age [SINGULAR] to come"
--"the wedding FEAST/SUPPER"
--the "G347 - 'shall sit down' [around a table/at a meal]"
--the TWO times He referred to "RETURN" [re: Himself], Lk19:12,15,17,19 "RETURN," and Lk12:36-37,38,40,42-44 [and their parallels], "when he will RETURN FROM the wedding..." (i.e. as an ALREADY-WED Bridegroom), THEN the meal!
--the times He told "the 12" they would "sit on 12 thrones, judgING the 12 tribes of Israel"
--when He referred to "in the regeneration when..." (that ^ reference [one of them])... "when the Son of man shall sit on the throne of His glory" [<--this being His EARTHLY "throne" upon His RETURN to the earth (there will be NO "goats" in Heaven, for example, Matt25:31-34 [parallel parts of Matt13:24,30,39,40,49-50])]
--ALL "Son of man cometh/coming/shall come/etc" references (referring to His RETURN to the earth; NOT "our Rapture") to "judge and to reign"
--many more references...
Up till the time He spoke His Olivet Discourse (and INCLUDING IT), He had NOT YET spoken to them ANYTHING about anything else but [what we call] "the promised AND PROPHESIED *earthly* Millennial Kingdom".
It is man's imagination that believes any and all of the above "contexts" ^ refer to "UP IN Heaven" INSTEAD, which they do not.
