There are 2 opinions.
In some cases I've heard that God reward anyone that obey Torah.
Also, I think I read somewhere in exodus that anyone living in Israel, be it foreigners or not, must not work on Sabbath or face death penalty. Would the guy that got stoned for picking sticks spared if he said, I am not jewish anymore (because as non jewish, he is supposed to break the sabbath)?
On others it's says that non jews should not follow Torah. In particular sabbath observance is no no.
Which one is right?
And in what way?
Say, because I am not jewish I must not follow Torah. Should I kill, steal, murder, etc.?
Should I work on Sabbath?
What's the difference?
