Good observation, PIZTJW. You are thinking like a corporate leader.
Maybe nothing "big" is happening this year, but it will happen. It has to. The WTBTS makes changes when the passage of time makes it necessary. THEN they label it as nu-light and as previously mentioned, all who disagree are spiritually weak. They will have to change the overlapping nonsense at some point. We already have multiple groups of "domestics", #1) FDS domestics, [ ONLY THE GB ] #2) Anointed/non-GB Domestics [ including Jesus' HAND-PICKED DISCIPLES, LOL!!!!!!], #3) The Great Crowd of [ other sheep]. All must partake, of course.
How easy, and " logical" it would be to simply make the "Great Crowd" and "other sheep" separate groups and drop the overlapping generation into obscurity. IF the 144,000 is understood to be symbolic, then you can have a " representative" on Earth indefinitely. These " holy ones " can be assisted by " Great Crowd Helpers" of the other sheep. Who the F knows when the four winds will be released?!?!? It can't happen until the full number of the SYMBOLIC 144,000 is gathered. When the Hell will that be?!?!?! SOON!!!
"Evidently", Jesus meant that the "generation" referred to the wicked who saw the sign, but refused to mend their ways. Jesus also " evidently " meant that the Great Crowd were anointed members who were not part of the FDS. Furthermore, Jesus EVIDENTLY meant that the other sheep have an earthly hope. Does this adjusted understanding contradict our understanding of the GT?!! Not at all! Evidently, Jesus meant that there would still be some Great Crowd/anointed domestics on Earth, taking the lead until the start of the GT!! When will that occur? We are wise not to speculate. The GT will occur when the "ASSYRIAN" attacks God's people. This will evidently coincide with the FINAL sealing of the Holy Ones of the symbolic 144,000. We cannot say when the final members of the 144,000 domestic members of the great crowd are sealed. Even so, the Earthly other sheep are eager to follow the Great Crowd wherever they go!!
Thanks be to Jehovah, who mercifully allows time to pass, thus making it possible for millions of Other Sheep to stream to his earthly organization, which is being lead by the faithful Great Crowd!!
