Among his many contributions to New Testament studies, Donald Juel was perhaps best known for his treatment of the ending of Mark's Gospel. He saw the open-endedness of Mark as powerfully unsettling for the reader who desires to tame and predict God's actions. In this series of essays, edited by Beverly Roberts Gaventa and Patrick Miller, theologians begin with Juel's own work and reflect on the "unsettling" in the context of their own work.
