DaMoshe:
“CS, it was reported by a Yaakov Zisholtz. I have no idea who he is. If I Google him, I don’t find much. So no, I wouldn’t trust it.
If you take one prediction the Rebbe made that came true, and use that as a sign that he was a Navi… there are plenty of people who made predictions that came true, including Shabsai Tzvi.
When my wife and I were going through fertility treatments, we were having a lot of difficulty, and our doctor told us to give up. We got a bracha from a Rav that our next IVF should work, and B”H it did. Does that mean he was a Navi?
There were sports players who predicted that they’d win a game, and they did. Maybe they’re nevi’im too?”
Firstly this was a major prediction that no one else made and came with a lot of achrayus. Secondly, in the sicha, The Rebbe referenced the Alter Rebbe as saying that Chassidim should only ask for spiritual guidance, because guidance for physical matters belongs to neviim as Shaul asked the Navi Shmuel about his lost donkeys… yet we see that all Rebbeim, including the Alter Rebbe, did dispense advice about physical matters, which indicates they were neviim.
Also, anyone can give a brocha and hope for the best, but at least in one instance, someone asked his Rebbe for not a bracha, but a havtacha, to which his Rebbe said that if he wants a havtacha, there’s only one place in the world- Lubavitch. The man did go to The Lubavitcher Rebbe, and did end up getting a havtacha. There are countless stories where The Rebbe told people not to have life saving surgeries, and similar situations, which turned out fine. Jem put out 2 books of such stories so far, with the individuals names and pictures, that they culled from their videoed interviews. There’s also much more online with jem media.
