Every single Jew anticipates and believes in the coming of Mashiach -- speedily, in our own days, and the preparation for this is the spreading of the wellsprings of the Baal Shem Tov ever outward. Accordingly, every Jew should utilize every opportunity to absorb the precepts of the Baal Shem Tov, which have been clarified in minute detail in the teachings of the school of Chassidus known as Chabad. (Significantly, this name is an acronym for the three stages in the intellective process -- Chochmah, Binah and Daas.) And the people who absorb these precepts will thereby be enabled to stand at the head of those who will soon be privileged to greet the righteous Mashiach.
