How do we know that a Gentile can be righteous by only following the Noahide Laws?

Question: How do we know for sure that a Gentile can be righteous by only following the Noahide Laws? Please give a short and simple answer.

It’s challenging to answer this with just a “short and simple” response. I will give a condensed answer, and also recommend a short video of a talk by the Rebbe on this subject:

Attaching the description of “righteous” to observance of the Noahide Laws can only be correct if they are accepted and observed correctly, as their name in the original Hebrew specifies: Sheva *Mitzvos* Bnai Noach = Seven *Commandments* [from G-d] for the Descendants of Noah. Paraphrasing the words of the Rebbe:

This means that in order for the Gentile’s observance to be truly righteous, it must include acceptance that there is an Entity which created and directs all creation, and that this Supernal Being conveyed through Moses at Mt. Sinai clear eternal instructions called Torah Law by which all people, Jews and Gentiles, are respectively obligated to guide their actions. This is the path of righteousness for which G-d will bestow eternal reward upon the person (see Rambam’s 13 Fundamental Principles, and Laws of Kings 8:11). In this light, the “Seven Laws of Noah” comprise seven broad categories, each of which includes numerous details, warnings and ramifications which need to be learned and followed.
