Noahide
From the entry for 5th of Tevet in “HaYom Yom,” compiled by the Lubavitcher Rebbe:
When Moshiach [the true Messiah] comes, we will realize the greatness of acknowledgement [belief] and earnestness, everyone’s pure faith in G-d and His Torah and commandments. Human comprehension – even on its highest level – is limited. But faith is a feeling that is boundless. Moshiach will explain the magnificent achievement of earnest service to G-d flowing from the heart.
