Further to the above posts, the relationship of the apostles to Christ must also be kept in mind. They were still disciples, a word which means "learners, or students". Like all good students they were always learning while in the presence of the Master, and what better way to learn than to ask questions. Thus, there is no evidence here that they themselves were expressing a doctrinal maxim, to be classed under "false expectations".
In fact quite the contrary. The only source of doctrinal imperatives is, now, as it was back then, Jesus Himself, and He made no statement one way or the other on this subject. Going insofar as to imply that this was none of their business. This should alert all potential disciples [or learners] that no definitive statement will ever be forthcomimg so the best methodology is: Keep your trap shut. This subject then becomes closed till He Comes again.
Those first century followers learned their lesson well never having made any statements regarding the exact time for the fulfillment of prophecy. Their role was to believe that they were, as we all should believe, living in the Last Days. Live as if this is the Last Days, but evangelize for tomorrow.
The GB on the other hand are not learning as disciples, but TEACHING. Just as Jesus taught the disciples, they have usurped this role for themselves and presume to TEACH the rank and file. So the comparisons are artificially created to excuse a massive fraud perpertrated on the the rest of the Watchtower followers.
A. Jesus taught the disciples. B. They learned by asking questions.
A The GB teach the rank and file. B. No questioning or debate is tolerated, even in the face of false teaching.
