With due respect, Wt to my knowledge has never publicly addressed the issue what happens to the billions that took the bread and the wine, but forgot that they should have stopped at 144 000.
Like wise, with respect, they have addressed it every day since their inception. I have no idea what “billions” of partakers you could mean. The sum total of all witness to ever live isnt a billion let alone the comparative few have partaken. The org teaches nobody outside is saved so you cant mean all other nominal christians who partake.
All that said, my remarks stand regarding the earthly hope as taugh by jw’s. The numbers dont add up from any perspective, no matter how you slice it, on the heavenly hope.
