In the Talmud, and codified by Maimonides, it is written that it is not sufficient for a non-Jew to just keep the seven laws in order to "have a portion in the world to come", that is, to be assured of eternal life.
As Maimonides says:
:One who accepts these [basic laws] is called: ''[[Ger Toshav]]'' in every place, and he must accept [these laws] on himself in front of three judges. And all who have taken upon themselves to circumcise, and twelve months have past without circumcision – this person becomes like other nations [who have not accepted the Noahide laws].<ref>Mishne Torah: Laws of Kings 8:10</ref>
A translation of Maimonides may be found [[Maimonides' Law of Noahides#Laws of Kings and their Wars' Chapter 8|here]]. (Please remember when reading other laws of Maimonides that he is only one authority, and other great Rabbis have given their opinions. Not all of Maimonides opinions have been accepted as the final opinion of Jewish Law (''halacha'').
