The term "expository" means basically "to expose." The aim of every sermon, to some degree, ought to be to expose or to uncover the meaning of Scripture.
However, preaching which is generally called expository makes exposition of Scripture passages its primary focus. In topical preaching, the topic (e.g. love, faith, forgiveness, etc.) controls the development and outline of the sermon. Scripture references are offered as supportive evidence. In expository preaching, the passage of Scripture under study controls the development and outline of the sermon.
Both types have their legitimate place in preaching. Sometimes one is better suited to the preacher's purpose than the other. The danger, however, is to overuse the topical approach because it is usually easier to prepare. Expository preaching that is creative and meaningful requires more digging. But the rewards for both preacher and people are also greater when time and effort are invested in preaching that is truly expository.
The purpose of this course will be to develop skills that will aid in the preparation and delivery of expository sermons.
