I don't know if anyone has brought this up so far, but I have two questions:
What if there are not enough "anointed" to complete a full set of Governing Body members? What if all the remaining anointed ones are in rest homes or in hospice, or are Altzeimers patients, or are simply alive but otherwise brain dead? Will members of the Great Crowd of Other Sheep no longer be sheep, but actual members of the Slave Class?
What happens if the number of partakers (especially among the older brothers and sister who have been faithful for 25 years or more all decide that they are specially chosen, quit having visions of New Earth human existence and realize that they too have the heavenly hope) begin to climb each year to an unsupportable number, like say 100,000? Or maybe even 144,500? Then what is the Watchtower going to do? Say that the apostles and early Christians are really part of the Great Crowd because they didn't really understand the Bible as well as modern Jehovah's Witnesses do?
I am quite sure that at some point the Watchtower will come out and admit that the 144,000 is a symbolic number using 12X12X1000 to show that the number was special, like 7X70 and 7000 years, etc. I think they will make this change within the next few years. That will really be freeeeking NOO LITE!
