Communicating for a Change by Andy Stanley is the best book I’ve read on teaching in Church settings. He’s got his particulars, that’s for sure, but it’s a great framework for thinking through message prep.
He’s an advocate for “one point” sermons. Just tell them one thing, with enough repetition and creativity, that it sticks. That concept has given me freedom and focus in my teaching.
With one point in mind, Stanley suggests a format of ME-WE-GOD-YOU-WE. Introductions that help people connect with “Me” gives some credibility and voice to listening for the time that follows – and it creates some tension that the listener wants to see resolved. “We” is a transition to how this topic matters to everyone – not just me. Then go to what “God” has to teach us on the subject, which should relieve the tension. Finally, hit a conclusion that aims at individuals (“You”) as well as vision for what the church (“We”) would look like if everyone applies this.
