Purification of the peoples of the world 'achieved by obeying Jews’: Belarussian Chabadnik Lugov
Preparing the peoples of the world for Liberation
The adoption of the seven commandments of Bnei Noah is a way to purify the peoples of the world so that they can be granted Liberation.
How can the peoples of the world prepare for disclosure during the Liberation?
Reply:
The purification of the peoples of the world for the transition to the age of Liberation is achieved1 by obeying the Jews during exile, as Yaakov said to Esab (Bereishit 27:40): "And you shall serve your brother."
The peoples of the world must teach and study the laws of the Torah relating to them, especially the doctrine of Hasidism (which refers to faith in G-d). This is a preparation2 for the fulfillment of the prophecy (Tsfaniya 3:9): "For then I will change the language of the nations (and make it) pure, so that all may call on the name of G-d to serve Him unanimously."
The adoption of the seven commandments of Bnei Noah is a way to purify the peoples of the world so that they can be granted Liberation.
