How to Write a Sermon
Writing a sermon that connects with your congregation starts with a clear structure. Most effective sermons follow a simple pattern: a relevant opening that meets people where they are, a scripture anchor, three to four main points, real-world application, and a clear call to respond. SermonPrep helps you build every one of those pieces in minutes.
Start With One Governing Idea
Haddon Robinson built his whole method around a single sentence he called the big idea. Before you write anything, boil the passage down to one claim you could say in a hallway conversation. If you cannot state it in fifteen words, keep working. A sermon carrying three or four competing themes leaves people holding nothing by Tuesday. Robinson tested this by asking two questions of every text: what is the author talking about, and what is he saying about it.
Your big idea should carry both an exegetical spine and a present claim. Ephesians 2:8-9 is about grace, but the sermon idea might be "God rescues people who bring nothing to the transaction." That version has traction because it names a real human instinct, the urge to earn standing. Write the sentence, tape it above your desk, and cut anything in your draft that does not serve it. Ruthlessness here saves you real trouble later.
Build the Outline Around Movement
An outline is not a table of contents, it is a route. Each main point should advance the argument, not restate it from a new angle. A common frame runs from tension to resolution: name the problem the text exposes, let it press, then show how the passage answers it. Preachers in the deductive tradition state the idea up front and defend it. Fred Craddock argued for the inductive route, delaying the claim so hearers arrive at it with you.
Three or four moves is plenty for a twenty-five minute sermon. Give each move a verb, because verbs force progress. "God confronts Jonah," "Jonah runs," "God pursues" reads as a story going somewhere. "Themes in Jonah" does not. Under each point, note the verse doing the work and one supporting observation. Resist stacking every good thought you found in study. The cutting-room floor is where good sermons are made, and a tight outline protects your hearer's attention.
Illustrate, Then Land the Charge
An illustration is a window, not decoration. It should let light onto the one idea, not show off the view. The best ones are concrete and short: a specific person, a specific moment, a detail your hearers can see. Avoid the movie recap that eats four minutes. Tim Keller often used ordinary examples, a debt forgiven, a costly adoption, to make grace feel expensive rather than sentimental. If an illustration needs heavy setup, it is probably the wrong one.
End with a call that fits the idea, not a generic push to try harder. If the text is about assurance, the charge might be to rest, not to strive. Name the specific response you are asking for and make it doable this week. Vague endings like "let us go forth and love" die on contact. When you draft your close, tools like SermonPrep can help you keep the application tied to the exegesis rather than drifting into moralism. Say the one thing, then stop.
Key Principles
- ✓Start with a topic your congregation is actually facing right now
- ✓Let the topic lead you to scripture - not the other way around
- ✓Build three focused points that each connect back to the central theme
- ✓Use one strong illustration per point - story, statistic, or real-life example
- ✓End with a clear, specific call to action your congregation can take this week

How long should a sermon be?
Most preaching runs between twenty and thirty-five minutes, though tradition varies widely. The real question is not the clock but whether every minute serves the big idea. A tight twenty-two minute sermon beats a padded forty. If you consistently run long, the problem is usually too many points or illustrations that overstay their welcome. Time yourself out loud, because reading silently always underestimates delivery by several minutes.
What is the big idea in sermon writing?
The big idea, a term from Haddon Robinson, is the single unifying truth of your sermon stated in one sentence. It combines the subject, what the passage is about, with the complement, what it says about that subject. Everything in the sermon, points, illustrations, and application, should serve that one claim. If a listener can restate it a day later, you have done your job.
How many points should a sermon have?
There is no sacred number, but three or four main moves suit most sermons. Fewer risks thinning the text, more risks losing your hearers. What matters is that each point advances the argument rather than repeating it. Let the passage set the divisions where possible. A tight two-point sermon on a short text is far better than a forced three-point structure the passage does not support.
Should I write out my sermon word for word?
It depends on how you deliver. Many preachers write a full manuscript for clarity, then preach from an outline drawn out of it. Writing everything forces precise thinking and guards against rambling. But reading a manuscript verbatim usually kills eye contact and energy. A middle path works well: write it fully, internalize it, then preach from key phrases so you sound like a person, not a document.
