The late Dr. E.K. Bailey, founding pastor of the Concord Church in Dallas, entitled, “Ten Reasons for Expository Preaching.”

In this booklet, Dr. Bailey defines expository preaching:

“An expository sermon is a message that focuses on a portion of scripture so as to clearly establish the precise meaning of the text and to poignantly motivate the hearers to actions or attitudes dictated by that text in the power of the Holy Spirit.”

Then Bailey gives ten reasons why the church desperately needs expository preaching:

1. Expository preaching creates a Bible-bringing congregation.

2. Expository preaching creates a Bible loving congregation.

3. Expository preaching a Word-conscious congregation.

4. Expository preaching forces the preacher to proclaim the whole counsel of God.

5. Expository preaching arms the people for spiritual warfare.

Expository preaching addresses the needs of people, which never occur to the preacher.

7. Expository preaching engenders tremendous interest in what’s coming next (in the text).

8. Expository preaching challenges the spiritual life of the preacher.

9. Expository preaching allows people to hear God’s word and not the preacher’s thoughts.

10. Expository preaching establishes the absolute authority of God’s Word as opposed to situational ethics.

Amen.
