This is NOT Expository Preaching

What expository preaching is not:

1. It is not a commentary running from word to word and verse to
verse without unity, outline, and pervasive drive.

2. It is not rambling comments and offhand remarks about a passage without a background of thorough exegesis and logical order.

3. It is not a mass of disconnected suggestions and inferences based on the surface meaning of a passage, but not sustained by a depth and-breadth study of the text.

4. It is not pure exegesis, no matter how scholarly, if it lacks a theme, thesis, outline and development.

5. It is not a mere structural outline of a passage with a few supporting comments, but without other rhetorical and sermonic elements.

6. It is not a topical homily using scattered parts of the passage, but omitting discussion of other equally important parts.

7. It is not a chopped-up collection of grammatical findings and quotations from commentaries without a fusing of the same into a smooth, flowing, interesting, and compelling message.

8. It is not a Sunday School-lesson type of discussion that has an outline of the contents, informality, and fervency, but lacks sermonic structure and rhetorical ingredients.

9. It is not a Bible reading that links a number of scattered passages treating a common theme, but fails to handle any of them in a thorough, grammatical, and contextual manner.

10. It is not the ordinary devotional or prayer meeting talk that combines running commentary, rambling remarks, disconnected suggestions, and personal reactions into a semi-inspirational discussion, but lacks the benefit of the basic exegetical-contextual study and persuasive elements.
