Only to follow the law G-d gave Noah? I mean if that’s the only goal while eating shrimp and pork then it’s kind of short coming isn’t it? Should gentile also obey some of the rules/mitzvah G-d gave the Jews? (kosher, clean state of mind etc etc)?
Washing your hand and keeping yourself clean is a no-brainer and I read that many Jews survived the black death just by following the Torah clean guide (washing your hand before eating, bathing) while gentiles didn’t. Is there anything akin to that still relevant today?
