So You Want to Preach Expositorily
I ran into a problem about four years ago that made me completely rethink how I approached sermon preparation. I had spent thirty hours on a series through Leviticus, and when I delivered it, the congregation looked like they were watching paint dry. The sermons were theologically sound, deeply researched, and utterly forgettable. I had followed all the rules. I just missed the part that matters most. That was the year I went back to Haddon Robinson and actually read his work instead of treating it like a reference manual I pulled out before conference season. The core concept in Biblical Preaching The Development And Delivery Of Exogenous Messages Haddon W Robinson is deceptively simple, which is probably why people gloss over it. Every text has a single big idea, and your job as a preacher is to let that idea do the work rather than burying it under five points and three applications.
The Big Idea Method Actually Works When You Stop Fighting It
Robinson's big idea concept isn't about making sermons shallow. It's about discipline. You read a passage, you determine what the author was saying to the original audience, and then you ask yourself: what is the one thing this text is trying to communicate? Not five things. One. Here is the counter-intuitive part that most preachers miss. The big idea is not your idea about the text. It is the text's idea. I used to think I was supposed to impose a theme onto a passage, like fitting a square peg into a round hole and hoping nobody notices. That approach produces sermons that feel manufactured. When you actually let the biblical author dictate the central thought, your sermon writes itself because you are no longer generating content, you are discovering it. The practical workflow looks like this. You start with exegesis, which means doing the actual work of reading the passage in its context, checking the grammar, understanding the historical setting, and seeing what the original audience would have heard. Then you move to homiletics, which is where you take that discovered truth and figure out how to communicate it to people who have never read Leviticus and probably don't care about its ancient literary context. The bridge between those two worlds is where your sermon lives.
What Actually Happens During Preparation
I spend roughly six to eight hours per message when I'm doing it right. That includes the exegetical work, drafting the big idea statement, building the outline, and rehearsing the delivery. The old way, the five-point approach, used to take me two full days and still produced mediocre results. The big idea method cut my prep time by about forty percent and made the actual preaching less exhausting because I was carrying less material and saying more with it. The introduction is where most preachers fail. They treat it like a warm-up or a joke segment. Robinson insists that the introduction needs to create genuine need. If your congregation doesn't understand why they should care about what you are about to say, everything that follows lands flat. I used to open with anecdotes about my grocery store mishaps. Nobody cared. Now I open with the tension in the text itself, or with a question that the passage actually answers. Your big idea statement should be one or two sentences, complete and declarative. Not a topic, not a theme word, a full proposition. "Faith without works is dead" is a big idea statement. "James and works" is a topic. These are completely different things. The topic is what you talk about. The big idea is what you want people to remember on the drive home.

A Specific Problem That Cost Me Three Sundays
There is a particular edge case in expository preaching that Robinson addresses but doesn't emphasize enough. Some texts simply do not produce a clean, singular big idea in the way Leviticus 17 or 1 Corinthians 11 do. I spent three consecutive weeks wrestling with Judges 13 through 16, trying to force Samson's story into a single propositional statement. Every time I thought I had it, the text rebelled. The narrative is too complex, too ambiguous, too loaded with literary irony to reduce to one clean sentence. My workaround was to shift from a propositional big idea to a thematic big idea. Instead of arguing that the text makes one specific claim, I let the text speak in multiple dimensions and held it together with a central thread. The thread in Samson's story was not a proposition you could memorize, it was a pattern: self-destructive strength. That gave me enough structure to build a coherent sermon without falsifying the text. Robinson would probably call this a softer application of his method, and he'd be right about that. But pretending every text fits neatly into a single proposition is where a lot of preachers start producing wooden sermons.
Delivery Matters More Than You Think
Robinson devotes significant attention to how you actually say the thing you have prepared. This is the part people skip because they assume delivery is innate. It isn't. I have watched brilliant exegetes destroy their messages through monotone delivery, poor pacing, and zero eye contact. The content was there. The transmission was broken. The exercise Robinson recommends, and I still use it, is reading your manuscript aloud at twice your normal speaking pace. This exposes weak transitions, unclear phrasing, and sentences that sound fine on paper but are impossible to deliver naturally. Most of my draft sermons fail this test on the first pass. I cut about thirty percent of the words during revision, which is exactly what should happen. A sermon that takes forty minutes to read should take twenty-five to preach. There is also the issue of eye contact versus note dependence. I used to read every word because I was terrified of forgetting something. What I discovered is that the congregation can smell manuscript preaching from three rows back. They know you are not with them. The workaround is to break your outline into index cards with only keywords, not full sentences. You glance, you remember, you speak. It feels less secure at first, but within three weeks your retention improves dramatically because you are engaging with the material actively rather than performing recognition.
Where This Method Breaks Down
I want to be straight about the limitations. The big idea method works best with texts that are clearly didactic, like Paul's letters or the Sermon on the Mount. Narrative texts, poetic books, apocalyptic literature, these resist the method more than Robinson admits. When you try to force Ezekiel or Revelation into a single propositional framework, you lose more than you gain. The text becomes a victim of your methodological preference. There is also the cultural problem. Congregations raised on five-point topical sermons will resist expository preaching at first. They want to know upfront what they are getting. The big idea method requires patience, both from the preacher and the people. I had members ask me after three months whether I was even preparing sermons anymore because nothing felt like the structured format they were used to. That is a normal adjustment period, not a sign that the method is failing. Another real bottleneck is time. If you are pastoring a congregation and also handling administrative duties, counseling, and a second job, the six-to-eight hour prep window that Robinson assumes is often unrealistic. In those situations, the method compresses poorly. You end up either skimping on the exegesis or skipping the homiletical bridge entirely. I have done both, and the difference in sermon quality is immediately obvious to anyone paying attention.

A Practical Alternative for Tight Schedules
When I cannot afford the full Robinson workflow, I fall back on a abbreviated version. I pick one key verse, extract one big idea from it, and build outward. It is not ideal. The sermons are thinner, less grounded in the full context of the passage, and sometimes the big idea feels slightly forced. But they are still better than a five-point sermon I threw together in forty-five minutes because I was exhausted. Perfection should not be the enemy of adequate. The underlying principle in Biblical Preaching The Development and Delivery of Expository Messages by Haddon W Robinson remains useful regardless of how much time you have. Know what the text says. Know what it means. Communicate it clearly to people who need to hear it. Everything else is decoration, and most of the decoration is unnecessary. I still return to this book every year before I start a new sermon cycle. Not because I need to learn the method, but because I need to remember why I am doing it. The danger in preaching is always the same: you start enjoying the performance more than the communication. Robinson keeps pulling you back to the text and the people, which is exactly where you need to be.
