Yes, they say as long as they are in the tribe, they need not worry about salvation, they're already saved. Is that right, or not?
Most don't look at it it terms of salvation. Most religious Jews embrace the Kabbalistic concept of "Tikun Olam" which means to repair the world. The ideal way of doing that is by living God's commands given at Sinai (not to say Christians don't). I think its a better concept than to believe the world is doomed hence focusing primarily on preparing for life in a different realm. After all, we are here for a reason. Its my belief correct doctrine cannot be the answer. Its my opinion that "do" is preferable to "believe". Moses apparenty beleived the same thing. Deut 30:
11For this commandment which I command thee this day, it is not hidden from thee, neither is it far off.
12It is not in heaven, that thou shouldest say, Who shall go up for us to heaven, and bring it unto us, that we may hear it, and do it?
13Neither is it beyond the sea, that thou shouldest say, Who shall go over the sea for us, and bring it unto us, that we may hear it, and do it?
14But the word is very nigh unto thee, in thy mouth, and in thy heart, that thou mayest do it.
