In particular, check out Zack Eswine's article, Seeking the Spirit: What Today's Preachers Can Learn from Charles Haddon Spurgeon.
Eswine lists "some of Spurgeon’s primary thoughts concerning a Spirit-inhabited sermon style":
- Use the Spirit’s appointed means
- Put your trust in the Spirit’s purpose and not in the Spirit’s means
- Seek the virtual preaching of Jesus
- Recognize the difference between mental and spiritual power
- See the Bible as your primary homiletics textbook
- Don’t forget to testify
- Engage the imagination and emotion
- Lean upon the community of believers
What would it have been like to sit in Spurgeon's classes? I hope this book gives a sense of what students would hear Spurgeon say about preaching if he were to speak with them in the hall, from the pulpit, or on a walk down the streets of London.
