1. Noahide laws...yes, there are still many nations which don not obey basic moral values, this can only help I think....
2. continue the return of Jewish people including Lost Tribes....yes, for sure.
3. trying to get a MORAL ETHICAL kind of multi-national assembly....yes (but probably impossible until Moschiah/Messiah is here...) Possibly this might help terminate the sickeningly immoral UN, maybe, by showing that something better can be achieved.
4. animal sacrifice? I personally don’t think this is necessary. King Solomon himself, the Jewish prophets and later rabbinical teachings all carry a strong emphasis on moral conduct plus sincere repentance for any transgressions (with recompense to try to set things right, where possible). I believe this is the way to go, and that a sacrificial ritual might even detract some folks from the moral teachings? At any event, the animal sacrifices have been so mis-understood in some religious traditions that it could raise some unnecessary hackles... maybe best to let that part of the ceremony go by, imho. Possibly excepting that detail...all in all this sounds like a good idea to promote some better morality (civilization) in the world... so I’m for it for sure... Its at least worth trying, pending the eventual Divine intervention of course. The world has so many evil people, societies, rulers... that any light, however small, in this darkness can only help, imho.
Sounds like a dress rehearsal for something in the Left Behind book series. Regarding animal sacrifice, have you ever wondered why Jesus overthrew the money changers’ tables in the temple? The Roman empire had many kinds of coinage circulating throughout the empire. You could only buy the clean sacrificial animals for temple sacrifices with Jewish coins. Thus the money changers converted non Jewish currency into Jewish coin and made a handsome profit in the exchange.
I was thrown by the idea of animal sacrifice, until recalling that Moses’ instructions from God directed that the priests should then eat the animal.
