Expositional preaching is preaching in service to the Word. It presumes a belief in the authority of Scripture—that the Bible is actually God’s Word; but it is something much more than that. A commit ment to expositional preaching is a commitment to hear God’s Word—not just to affirm that it is God’s Word but to actually submit yourself to it.
