Once one makes this step, the 'size' of one's portion in the world to come is determined by prayer, repentance, good deeds and good character. This may sound very similar to the teaching of other religions, particularly within the Abrahamic tradition, and it should be so. Judaism teaches that the Noahide covenant is the foundation of any proper society and religion.
According to Rabbinic tradition, the best way to mark the decision to become a part of the Noahide Covenant is to make a declaration.<ref>Maimonides holds that the declaration is only required for a Ger Toshav. He holds that Ger Toshav only applies to those who live in Israel under a soveriegn sovereign Jewish (Torah) State, others disagree. According to many authorities, there is value to the declaration of a person before a rabbinical court even outside of Israel.</ref>
