The most recent one I heard of (and I’m surprised that no one else posted it) is from R’ M. Solomon.
He was contemplating retirement, and he says that his Rebbi Muvak (not sure which name was used) said, if you stay with BGM, “est du derleben Moshiach (you’ll live to see Moshiach)
He then said to the audience, “raboisai…. I’m not a yougster anymore….Moshiach’s arrival is imminent!
Great story, but. The problem is, we have in our posession countless haftochos (assurances) from the Neviyim themselves that Moshiach arrival is in our hands, and all we need to do is play our hand right and he will be here in an instant. Yet we just roll thru our daily routine, business as usual.
Not to worry, though. One of the mamorim is “ain Ben Dovid boh, eleh b’hesech ha’daas” (loosly translated as: Moshiach will come when least expected)
NU? Ad Mosai! (I was gonna say Moshiach now, but I did’nt want to start a riot)
