Many times as a Jew I think in the back of my head that certain question’s answers I greatly ponder will be revealed to me when I die.
I’ll give an example. A few distant relatives of mine were assumed to have perished in the Holocaust. But that is just because of the small information we had. It’s not necessarily true. And even if they did, we don’t know how and where etc.
What are sources in Judaism confirming or not this topic?
