Some homiletics professors tell their students not to use books of illustrations. These are the professors who use the same three sermons everywhere they go and don’t face the challenge of writing two or more fresh messages every week. While most illustration books tend to be stale, re-packaged material, there are also worthwhile offerings. Perfect Illustrations for Every Topic and Occasion (Tyndale House) contains more than 300 illustrations taken from PreachingToday.com, a web-based resource sponsored by Christianity Today, Inc. The book also includes a helpful CD-ROM containing the same text as the book.
