If Noahide concept is not a subjective rabbinic interpretation of Tanach, (Bible) can you please cite the Tanach sources where the G-d of Israel explicitly laid down what you claim for the 70 Nations? If Judaism does not proselytize, how are the 70 Nations suppose to know about what you claimed since they weren't "present" at Mt. Sinai (where the Torah was given to the Jewish people)?
The Seven Laws of Noah are not only for the 70 Nations. They are for all descendants of Noah, which includes all of us. However, the Jewish people accepted the Torah, which the 70 Nations rejected, so we have been given not only the seven laws, but many more laws, too. Much of the Torah is learned from the Oral Torah (Talmud) which includes the details of these laws.
Judaism does not proselytize by trying to bring the other nations into the Jewish people, but we certainly are obligated (privileged) to help the nations live righteous lives. This is one of our two main tasks. We are to be a “nation of priests,” and we are to be a “light unto the nations.” Besides helping each other, we must help non-Jews come to righteousness, too. We do this by teaching them these seven laws.
These laws are prohibitions against idolatry, blasphemy, murder, adultery, stealing, eating flesh that was taken from an animal before it was killed, and not having just courts in their lands.
Another Question on, “I Converted”
Why one must assume that the potential candidate for conversion was a Jew in a previous life. The whole reincarnation thing is far removed from actual Torah.
As I am quite sure that you are aware, this is straight from Hinduism.
With all of the obsession against yoga (a good obsession btw) I cannot fathom why the falseness of the "previous life" business is pushed as part of our faith. Judaism is what our forefathers do, and Torah is the unequivocal truth. Sometimes and in some areas there exist distance.
I do believe reincarnation is far removed from the truth.
Look in the book, The Mishna Brurah, Laws of Yom Kippur, Mincha. There is a story there of a man who refuses to repent. He says, “I am so used to sinning that I am going to continue to sin, and worse comes to worse, G-d will come and kill me.” The commentator there says, “No, this man must repent, or he will have to come back to this world again, and again until he does repent.”
Also, look in the prayer book at the prayers that we say when we retire at night. “I hereby forgive anyone who has angered me,… in this incarnation or in any other.”
We see here, in these books of Jewish Law and prayer, that reincarnation is part of our Torah.
