Why aren't heaven and hell more discussed in the Torah? How can we really believe in Olam Haba if we don' have proof that it exists? Why do we want Techiyat Hametim to happen if Olam Haba is so amazing? Who goes to heaven and who doesn't?
Why do we speak so much about Eretz Yisrael?
1. This mitzva has been neglected for two thousand years.
2. It is a Mitzvah that is equated with the rest of the Mitzvot put together.
3. It is the only Mitzvah which the goyim are trying to prevent.
