Since the heavenly hope was the only “calling” throughout the centuries
Fm: really? Peter, the rock, wrote of "awaiting a New heaven and a NEW EARTH."
At the last supper, Jesus served the emblems to people with an earthly hope. billions partook since, the fact that they did not believe in the overlapping groups does not matter. Wt doctrine, or any amalgam of it, is erroneous and irrelevant to the great universal scheme.
With "heaven" having so many meanings, how about a material heavenly hope, seeding life on trillions of heavenly bodies with heavenly (perfect} bodies, carrying proven good qualities from the experience here, -- revived there?
Who says there are only 144 000 places ? that elite numbers is just the Groom's entourage (wherever he goes) There were already millions and millions of angels, , and possible places (many mansions) for that many more newcomers.
imho. you are taking this house of cards structure of the talking snake story too seriously. The magnificent universe before us tells a more glorious picture than that pathetic tale's denouement. .
