The What and Why of Expository Preaching

At the heart of everything we believe and practice as followers of Christ stands one unshakable foundation: the Word of God.

Scripture makes it clear that God has revealed Himself to us. While creation testifies to His power and divine nature (general revelation), God has spoken most clearly and definitively through Jesus Christ and through His written Word (special revelation). As Paul writes in 2 Timothy 3:16–17, all Scripture is breathed out by God and profitable for teaching, reproof, correction, and training in righteousness. Peter echoes this truth in 2 Peter 1:3–4, reminding us that God has granted to us everything we need for life and godliness through the knowledge of Him.

If that is true—and it is—then the Word of God is not merely helpful. It is authoritative. It is sufficient. It is definitive for all matters of faith and practice.

That reality must shape how we function not only as individual believers but as a church family.

The Word Shapes the Church

The Bible is not silent about how God’s people are to live and function together. Paul instructed Titus to “put what remained into order” and appoint elders in every town (Titus 1:5). He urged Timothy to guard sound doctrine and prevent false teaching (1 Timothy 1:3–5). He reminded the church that it is “the household of God… a pillar and buttress of the truth” (1 Timothy 3:15).

In other words, the Word of God governs the life of the church.

It influences what we do when we gather on Sundays.
It shapes how we understand membership and leadership.
It directs how we teach, disciple, worship, and serve.

If Scripture is the standard, then we must know it in order to obey it.

And that raises an important question: Who is responsible for teaching the Bible?

Who Teaches the Bible?

In one sense, every believer shares this responsibility. Colossians 3:16 calls us to let the Word of Christ dwell in us richly, teaching and admonishing one another in all wisdom. The church is a Word-saturated community where believers encourage one another with truth.

But Scripture also gives a unique responsibility to pastors. Ephesians 4:11–14 tells us that Christ gave shepherds and teachers to equip the saints for the work of ministry and to build up the body of Christ. An overseer must be “able to teach” (1 Timothy 3:2). Faithful preaching and teaching are central to pastoral ministry.

Why? Because the primary purpose of preaching and teaching is clear: that the hearer would know what God has said, understand what God meant, and walk in obedience to His commands.

The authority does not rest in the personality of the preacher. It does not rest in creativity or charisma. It rests in the Word of God.

“Thus says the Lord”—not “Thus says the man.”

You cannot obey what you do not know.
You cannot teach what you do not understand.
You cannot rightly worship the One you do not truly know.

Right theology produces right thinking. Right thinking produces right living.

This means that preaching must aim for both explanation and exhortation. Explanation without exhortation leads to mere information. Exhortation without explanation leads to frustration and exasperation. As Nehemiah 8:8 demonstrates, faithful leaders read the Word clearly and gave the sense so that the people understood it.

Understanding must precede application.

Topical vs. Expositional Preaching

When it comes to preaching and teaching the Bible, there are generally two main approaches: topical and expositional.

Topical messages often gather verses from different parts of Scripture around a particular subject. While this approach can be helpful at times—especially in systematic theology—it can also become driven more by the preacher’s agenda or perceived needs than by the text itself. There is always the danger of taking verses out of context or reading ideas into the text (eisegesis) rather than drawing meaning out of it.

Expositional preaching, on the other hand, focuses on a particular passage of Scripture within its context. The aim is to understand what God intended to communicate through the biblical author to the original audience—and then faithfully apply that truth today.

The point of the text becomes the point of the sermon.

Exposition simply means “to explain.” An expositional sermon is one in which both the content and the intent of the message are controlled by the content and intent of the passage itself. The preacher says what the passage says and seeks to accomplish what the passage seeks to accomplish.

Often, this approach involves preaching verse by verse through books of the Bible rather than jumping from topic to topic. This method brings several important benefits.

It forces the preacher to submit to the authority of God by submitting to His Word.
It keeps the message anchored in context.
It requires dealing with difficult or uncomfortable subjects.
It challenges preconceived ideas and personal biases.

And it teaches the congregation how to study the Bible for themselves.

Rather than depending on someone else to tell them what to think, believers learn how to read carefully, think critically, and apply faithfully. They learn to let Scripture—not experience, emotion, or culture—have the final say.

This impacts every ministry of the church.

Common Objections

Some raise objections to expositional preaching.

“Expository preaching is boring.”

But boredom is not the result of faithful exposition. It is the result of poor preaching. When the living Word of the living God is clearly explained and passionately applied, it is anything but dull.

“It’s too academic.”

Explanation serves transformation. We cannot be transformed by truth we do not understand. Clarity fuels growth.

“People need practical help, not lectures.”

True application flows from true understanding. Practical help disconnected from biblical truth may feel useful in the moment, but it lacks lasting power. God’s Word changes hearts, not human opinion.

Letting God Speak

At its core, expositional preaching and teaching is about letting God speak on His own terms.

It is about opening the Bible, reading what is there, explaining what it means, and calling God’s people to respond in faith and obedience.

It is an act of humility. It acknowledges that we do not set the agenda—God does. We do not define truth—He does. We do not determine what the church needs most—He does.

If the Word of God is truly sufficient for life and godliness, then our greatest need every week is not a new idea, a clever theme, or a cultural commentary.

Our greatest need is to hear from God.

And we hear from Him when His Word is faithfully explained, carefully applied, and joyfully obeyed.

That is why expository preaching matters.
