JP also seems to be laboring under the misapprehension that I am Jewish myself. He seems to think I wrote parts of the TaNa"KH!!!
Not to get into a big theological thingie here (which I'm not as qualified to discuss as you are, wideawake), but the reason the Torah says so little about the afterlife is because this world, the world G-d created in the beginning, is in fact going to be the main part of the afterlife! Obeying the commandments (Mosaic for Jews, Noachide for non-Jews) helps to refine and perfect the universe so that it will one day be the paradise G-d intended it to be, and the ultimate reward is to be resurrected and live here during that time.
And he’s gone.
