There is a divine dream which the prophets and rabbis have cherished and which fills our prayers, and permeates the acts of true piety. It is the dream of a world, rid of evil by the grace of G-d as well as by the efforts of man, by his dedication to the task of establishing the kingship of G-d in the world. G-d is waiting for us to redeem the world. We should not spend our life hunting for trivial satisfactions while G-d is waiting.
-Rabbi Abraham Joshua Heschel
