I remember asking about the limitations of the Rabbinical rulings, based on "לא בשמים היא" within Judaism.
After other questions dealt with deciding whether Gentiles in general or any specific group (the Samaritans) is entitled to a piece in our World to Come (WtC), I came up with the question of the validity of our speculations.
It seems that those two belong to two different domains - one is what our Sages are allowed to deal with (this world) and what will always remain G-d's domain (WtC).
I would speculate that in this relativistic world, G-d "does not care" what the Halachah says only that people follow it (like that the Sages ruled that משיכה buys instead of G-d's כסף) but in the WtC who can limit G-d to think we know better?
Hence the question: as our scriptures do not deal almost completely with the questions of the WtC and everything we know about the WtC is Rabbinical thinking how valid are those and how obligating are they to G-d?
