Preachers mount the pulpit steps terribly burdened by the conviction that they are somehow responsible for the growth and spiritual well-being of their congregants. How, they ask themselves, can mere words communicate the reality of God, bring life to a congregation, or foster spiritual growth? This study argues that effective sermons function much like Jesus' parables--by bearing witness to divine power.

Michael Knowles has written a stunning and demanding book on preaching. His central point is the life-giving power of God, which is exemplified in Jesus's agricultural parables. Over and against 'how to' books, Knowles advocates homiletical helplessness as a primary virtue, which involves putting to death our reliance upon rhetorical techniques.
