yadda_yadda,
I didn't say he thought it might never happen. He obviously thought it might happen, he just didn't prophesy that it would happen. You framed your post as though this was a prophecy that had to be fulfilled, and that isn't how we communicate about things that only might happen. Not in English, anyway.
Jesus did not speak of two appointments, as you claimed, he spoke of one appointment that might happen, but only if a certain set of conditions was met and a certain judicious identification could be made. He also spoke of another eventuality that might happen, but only if a different set of conditions was met. Do you disagree with that? If so, why?
