Every pastor has a canon within the canon.
Not officially, of course. No pastor would say they ignore entire sections of Scripture. But when you map a decade of sermons against the 66 books of the Bible, patterns emerge that surprise even the most intentional teachers.
The Data Tells a Story
We looked at over 500 sermon libraries across churches of various sizes. The average teaching pastor had preached from just 22 of the 66 books of the Bible over a three-year period. The Old Testament prophets — particularly the minor prophets — were the most consistently overlooked section.
This isn't a failure of intention. It's a natural consequence of preaching in response to what feels urgent. Pastors gravitate toward the books that feel most applicable to their congregation's current needs. Romans for theology. Psalms for worship. James for practical living. The Gospel of John for evangelism seasons.
But the books you skip tell a story too.
Why Blind Spots Matter
A congregation's theological imagination is shaped by what they hear from the pulpit. If they never encounter the lament of Habakkuk, they may struggle to bring their honest questions to God. If Amos never gets a sermon series, justice might feel like a political issue rather than a biblical mandate.
Blind spots aren't character flaws. They're information gaps. And the moment you can see them, you can address them.
What You Can Do About It
The first step is simply mapping what you've covered. Most pastors are surprised when they see it visually — a heatmap of the Bible where some sections glow bright and others sit completely dark.
From there, it's not about forcing yourself through Leviticus verse by verse. It's about making intentional choices. A four-week series on the minor prophets. A single sermon from Lamentations during a season of grief. A study guide that walks your small groups through a book you've never preached from.
The goal isn't coverage for coverage's sake. It's giving your congregation the full counsel of Scripture — because they're trusting you to.
The Heatmap Changes Everything
When one pastor we spoke with saw her biblical coverage heatmap for the first time, she said the quiet part out loud: "I've been preaching my comfort zone."
That's not a criticism. It's an observation that opens a door. And the pastors who walk through it consistently report that their preaching becomes more intentional, more diverse, and more resonant with their congregation's actual needs.
