As preachers, we recognize that it is all too easy to say the wrong thing in a message and derail a sermon. In their book What Not to Say (Westminster John Knox), John Holbert and Alyce McKenzie seek to help preachers avoid “the common mistakes that can sink your sermon.” The book offers suggestions about what not to say (and what to say) about God and the Bible, about yourself and about your people, and at the beginning, middle and end of the sermon.
