No problem. Glad to have helped.
If you heard that in English it is possible that the people who said it don't really understand what is really said on this matter.
The best way I can explain it is like this. All non-Jews in the world are responsible for the 7 Noachide laws. 6 of which were given to Adam and his descendents and the 7th was given to Noach and his descendents. Avraham (Abraham) and his children accepted an additional mitzvah of brith mila on the eigth day for a baby male that is born. Brith Mila for anyone who wanted to join Avraham in the mission he was given by Hashem. When Israelis/Jews were Mount Sinai Hashem gave the entire nation 613 mitzvoth of the Torah. This was given and accepted by the entire Jewish nation of that generation and there are some sources that say that all future Jews who would keep Torath also accepted it, since Hashem is not bound by time but is the Creator of time. If a non-Jew keeps the 7 mitzvoth of Noachide as Hashem specified them they are granted a place in the world to come by Hashem. All Jews who keep Torath Mosheh have a portion of the world to come if Jews as a nation keep the 613 mitzvoth. Much of the benefit of such is hidden away from Jews in this world with the higher benefits of only be realized in the world to come.
That being said, the folloing example can be used. Imagine a military with all of its different units, jobs, functions, etc. Using a US navel example.
- The consideration is that the non-Jewish nations that keep the 7 mitzvoth are:
- The Jewish nation that keeps the 613 mitzvoth is like United States Naval Special Warfare Command and Operational Test and Evaluation Force.
Both are considered to be in the Navy. Yet, the functions are different and the type of rewards or recognition of the service are different. Further, anyone from the nations can join the Jewish nation by way of conversation. The same that someone in the Navy who meets certain requirements can try to become a Navy Seal.
