The Children of Israel turn from grief at the punishment of having to wander the desert for forty years in the parsha/portion of Shelach Lecha to grievance in the parsha of Korach. Korach and his cohort challenge Moshe's power by saying - rav lecha - you have taken too much. In her sermon, Rabbi Dianne Cohler-Esses explores the role of grief in our lives and the potential it has to prepare us for activism.
