Dear Fellow Preacher,
Someone has said that each different form of Christian piety concentrates on one of the following: thinking, feeling, or doing. Starting from only one of these determines your theology, your practice, and, to a large degree, your worldview. In the Gospel for the Third Sunday of Advent, Luke 3:7-18, John the Baptist preaches repentance with great urgency, but this repentance involves all three human functions: changing one's thinking, enlivening one's compassion, and -- perhaps most important -- becoming actively involved in doing justice.
