Wait for the silence and the rabbit in the headlights moment.
You think that JWS won't have an answer about this? They most certainly will.
Here, i'm gonna put my JW hat on, and answer your question:
Well Fall Guy, we wouldn't expect that the bible would tell us the exact make-up of the GB, location or the number of members, etc, but the bible does indicate in multiple places that there will be a faithful and discreet slave responsible for dispensing spiritual food at the right time, such as Mat 24, Mark 13, Luke 12.
God has always communicated with its people via a channel, and if we think that our organization is the only truthful one, then logically someone must take the lead in teaching and organizing the worship. How else could we make sure that the brotherhood is learning the same things, and is coordinated in preaching the word of the good news?
