IMO Noahide Laws or Noahidism is not really different from
Orthodox Judaism, as you cannot undrstand love and Grace from GOD unless you go deeper into hebrew scriptures, and that is why I think most Pagans were never interested in the Noahide Laws....
Since GOD is LOVE first before he is a Teacher of Philosophy, Law and Physics, people were looking for the *Love of GOD* and how that could impact there broken lives
and that is why Jesus came for the lame, the sick, the Lepors the ones that were considered (Un-important) by the Jewish Teachers of the *Law*
What makes people want GOD is Love not Law, but when you convert your heart twoards GOD’s love then your conversion prompts you to do his law out of Love not a robotic mind.
The Jewish Scriptures are primarily for Jews. Non-Jews are forbidden to "delve deeply" into any part of Torah other than what they are commanded in the Noachide Laws. As a matter of fact, the translation of the Hebrew Bible into another language for the first time is actually one of the things mourned on `Asarah BeTevet.
Your chr*stian terms and assumptions simply do not apply. I'm sorry if you can't understand that, but that's the way it is. The Torah is not a reaction to the sin of Adam; it preceded the Creation by 974 generations (and no, I do not understand it either). The universe is entirely derivative from the Torah. Basically, the world was created so the Jews could observe the Torah. That's quite a difference from the chr*stian conception of the Torah as a reaction to the sin of Adam and as a "foreshadowing" of chr*stianity.
While there is certainly such a thing as "grace" I am not at all sure that it is identical to the chr*stian concept of "grace," which has so many assumptions built into it of "the devil" taking over the world, G-d having to buy it back (???), and people born in slavery to the devil and not having a relationship with G-d at all until they are "born again." The whole concept of G-d having an enemy of evil counterpart of some kind is alien to the Jewish worldview. It isn't even monotheistic.
I don't know if I can explain anything in a way that you will understand it. I've been a Noachide for twenty years and am still learning. All I can say is that your chr*stian assumptions simply do not apply.
Is that enough?
There is a very big difference. Noahide laws are for the non-Jews. Judaism is only for the Jews. Different laws; different standards.
What makes people want GOD is Love not Law...
According to the Jewish Bible (aka the Old Testament), God wanted specific people for himself, not the other way around.
