The “scripting” of preaching can, like a bad play, be pre-
dictable and dull. Even worse, it can be manipulative. A play is
said to be “preachy” when it uses the medium of drama to coerce
a certain (and unvarying) response. Good preaching is direct,
understandable, and dynamic, but it also has a certain quality of
open-endedness. It is evocative—it stirs and “opens up” without
substituting for the work of the Spirit.
