The Slide That Killed the Sermon
Every experienced preacher has had the experience: you put up a slide, and the moment you do, the congregation starts reading instead of listening. The beautifully crafted sentence you're speaking is competing with the mediocre one on the screen—and the screen is winning.
Or worse: the video clip you chose was longer than you realized, the emotional tone was slightly off, and by the time it ended the congregation had drifted somewhere you didn't intend to take them.
Visual aids are powerful tools. Like all powerful tools, they can help enormously—or damage what they're meant to support. This article is a guide to using them wisely.
The Principle: Visuals Serve the Word
The fundamental principle is simple: visual aids exist to serve the spoken Word, not to substitute for it or compete with it. When a visual element is doing something that the preached word is already doing effectively, it is redundant at best and distracting at worst. When a visual element does something that the spoken word cannot—helping people see rather than just hear—it earns its place.
This means asking, before every slide or object you plan to use: What does this add that my words cannot provide? If the honest answer is "not much," leave it out.
Slides: Friend or Crutch?
Presentation slides (PowerPoint, Keynote, ProPresenter) are the most common visual aid in contemporary preaching. Used well, they:
- Help visual learners retain the structure and main points of the sermon
- Display Scripture passages so the congregation can read and engage simultaneously
- Provide visual reinforcement for key illustrations (a photograph, a map, a chart)
- Create aesthetic atmosphere that supports the emotional tone of the sermon
Used poorly, they:
- Turn the sermon into a lecture with bullet points
- Reduce the preacher's eye contact and spontaneity (reading off slides rather than preaching)
- Clutter the visual space with too much text, distracting rather than reinforcing
- Create a dependence that makes the preacher unable to deviate from the slide sequence
A practical guideline: less text, more image. If a slide has more than ten words, consider whether it needs to be a slide at all. Scripture text is an exception—displaying the passage is almost always helpful. But sermon points as sentences on a slide often compete with the speaker rather than supporting them.
Maps, Timelines, and Diagrams
For biblical and historical content, maps, timelines, and diagrams can be extraordinarily useful. Showing the geography of Paul's missionary journeys, the timeline of the exile, or a simple diagram of the tabernacle gives the congregation visual context that enriches understanding without competing with proclamation.
These are often the best use of slides in preaching—providing information that is genuinely difficult to communicate verbally and that helps the congregation stay oriented in the material.
Video Clips
Video clips can be powerful. A two-minute documentary segment, a news report, a film scene—when chosen well, these can create emotional resonance and cultural connection that words alone might not achieve.
The risks:
- Length: anything over ninety seconds becomes a separate event that the sermon has to recover from
- Tone mismatch: a clip that's almost right but not quite can pull the congregation in the wrong emotional direction
- Technical failure: a video that won't play or plays with bad audio can be deeply disruptive
Use video sparingly and intentionally. Test it beforehand—every time. Have a plan for if it fails.
Physical Objects
Sometimes the most powerful visual aid is an object you can hold—bread and a cup while preaching on the Lord's Supper, a seed while preaching on the kingdom, a stone while preaching on the empty tomb. Objects engage embodied attention in ways that screens cannot.
The risk is that the object can become a distraction if handled awkwardly or left visible too long. Use them at the right moment, handle them with intention, and set them aside when they've done their work.
The Blank Screen
One of the most underused visual choices is the blank or faded screen. When you're making a crucial emotional or theological point—when you want the congregation fully with you, not partially reading—go dark. Remove the visual competition entirely.
Preacher: preach the Word. Screen: disappear. It's a simple technique that dramatically increases the relational impact of key moments.
Designing for Your Context
Your context matters enormously. A downtown church with a high production team can do things a rural church with one projector cannot. Don't compare. Work with what you have.
What every context can do:
- Display Scripture clearly
- Use images intentionally rather than decoratively
- Keep slide text minimal
- Practice transitions so they don't disrupt the flow
GoRhema helps with the content architecture of sermons—giving you a strong structural foundation so that when you add visual elements, they're enhancing a sermon that already works, not propping up one that doesn't.
The Message Always Leads
A final principle worth stating plainly: the technology serves the preacher, not the other way around. If the slides went down, could you still preach the sermon? If the answer is no, the sermon has a problem that slides cannot fix.
Visual aids at their best are the frame around a painting—they set it off, direct attention, provide context. They are never the painting itself. The painting is the proclaimed Word, which needs no technology to be the power of God for salvation (Romans 1:16).
That's the sermon worth preaching. Visual aids just help people see it better.
