I recall an Awake! or Watchtower article in the late 1960s that spoke frankly of the disappointment that many older ones had felt that the end had not yet arrived - and then it went on to say something like, 'How grateful we should be that it had not yet arrived for it enabled more to come into the organization in readiness for the end".
Always an answer. Always.
You could re-tred that article today - almost 50 years later - and say the every same thing - except you'd probably have to sidestep the fact that fewer and fewer non-JWs convert to the organization nowadays - most of the "growth" is from born-ins.
