Did he make a definite prediction? Or did he say something like "I don't see how we could be here much longer"? I'd like to know the exact quote.
A definite prediction or prophecy is
different from someone just stating an educated guess or melancholy opinion of the world.
I agree with Renda; I don't think there's enough preaching about Jesus coming back.
However, the definite predictions get old; the dates have come and gone and come and gone again way too many times.
