Many small church pastors preach topically because it feels more immediately relevant. They pick a subject their congregation is facing and build a series around it. That approach has its place. But a steady diet of topical preaching tends to produce congregations that know the pastor’s opinions on a lot of subjects and the Bible’s teaching on fewer of them.

Preaching through a book of the Bible forces you to deal with the text as it comes. You cannot skip the hard passages. You cannot avoid the uncomfortable doctrines. You preach what is there, and over time your congregation develops a genuine familiarity with Scripture rather than a collection of proof texts.

Why Expository Preaching Serves Small Churches Well

Small churches often have the same pastor for many years. That is a gift. It also means the congregation can become overly dependent on the pastor’s personality and preferences rather than on Scripture itself. Expository preaching through books of the Bible anchors the congregation to the text rather than to the preacher.

It also solves the sermon planning problem. When you are preaching through Romans, you know what you are preaching next week. And the week after. And the week after that. The planning burden drops significantly, which matters enormously for a bi-vocational pastor.

Choosing Your Book

Not every book of the Bible is the right starting point for every congregation. Consider:

• Where is your congregation spiritually? A congregation that needs foundational gospel teaching might start with Mark or Romans. A congregation struggling with practical Christian living might start with James or Philippians.
• How long do you want the series to run? A short book like Philippians (4 chapters) can be preached in 8 to 12 weeks. Romans will take 2 to 3 years if preached carefully.
• What is your own familiarity with the book? Start with a book you know well enough to teach confidently. You will go deeper as you prepare, but starting from zero on a difficult book is harder than it sounds.

Planning the Series

Before you preach the first sermon, do the following:

Read the Book Through Multiple Times

Read it in one sitting. Read it in different translations. Read it slowly with a pen in hand. You need to know the whole before you can preach the parts well. The argument of the book, its structure, its major themes, and its key turning points all need to be in your head before you stand up to preach the first passage.

Divide the Book Into Preaching Units

A preaching unit is a passage that holds together as a unit of thought. This is not always the same as a chapter division. Some chapters contain multiple preaching units. Some preaching units span chapter breaks. Work through the book and identify natural divisions.

Build a Preaching Calendar

Map your preaching units onto your calendar. Account for Christmas, Easter, and any other occasions when you will preach a standalone sermon. Build in flexibility for pastoral situations that require a change of direction. A rough calendar 3 to 4 months out is enough.

Preparing Each Sermon

Expository sermon preparation follows a consistent pattern:

1. Read the passage repeatedly in multiple translations
2. Observe what the text says, who, what, when, where, how
3. Interpret what the text means, what was the author communicating to the original audience?
4. Identify the main point, one sentence that captures the central truth of the passage
5. Apply the main point, how does this truth change how your congregation thinks, feels, or acts?
6. Build the sermon structure around the text’s own structure, not an outline you impose on it

Pacing the Series

The most common mistake in expository preaching is going too slowly. A congregation that spends six months in the first chapter of Romans will lose the forest for the trees. Move at a pace that allows you to cover the book’s argument while giving each passage the attention it deserves.

A rough guide: one to two verses per sermon is too slow for most passages. A paragraph or natural unit of thought is usually the right size. Some narrative passages can cover an entire chapter in one sermon.

Sustaining the Series

Long series require intentional sustaining. Every few weeks, step back and remind your congregation where you are in the book, where you have been, and where you are going. Help them see the argument developing. This is especially important for longer books like Romans or Acts.

Vary your approach within the series. Not every sermon needs the same structure. Some passages call for more narrative. Some call for more doctrinal exposition. Some call for more direct application. Let the text determine the approach.
