A faithful preacher’s role is to move from exegesis to persuasive exposition, to communicate biblical truth with clarity, and to bring credibility as a godly man to the pulpit, David Helm told attendees of the 2022 E.Y. Mullins Lectures, held October 26–27 at Southern Seminary.

Helm is senior pastor of Christ Church Chicago and author of numerous books, including 1 & 2 Peter and Jude, The Big Picture Story Bible, One-to-One Bible Reading, and the 9Marks volume, Expositional Preaching.

The theme of the Mullins lectures was “Persuasive Preaching.” Helm also serves as board chairman for the Charles Simeon Trust, a ministry that encourages expository preaching and conducts preaching workshops worldwide.

“The preacher, in his preparation, is always moving from the biblical text to presenting what he has learned,” Helm said. “Only after the hard work of exegesis and theological reasoning can the preacher turn to having a word for today.”

Helm said all sermons should make an argument to persuade. The preacher isn’t simply presenting information but is calling for an obedient response. To provoke a response, however, the sermon must present a persuasive argument that is clear and rational.

“Preachers should fashion an argument that will lead the listener to a point of determination and act of the will. You must make an argument,” Helm said. “Christianity is not meant to just state things or be part of the conversation. We are actually trying to persuade people. Persuasion requires making a reasonable, accessible, and delightful argument.”

According to Helm, pastors too often study the text and understand the Bible’s meaning without formulating the message into a persuasive sermon. By Sunday, preachers need to be ready to present the argument in a persuasive sermon.

“Your job isn’t to recapitulate everything you learned in your study,” Helm said. “You don’t make arguments up—you take arguments up. Your text has already made an argument to the first readers and your sermon must shape that argument for your listeners.”

Faithful preachers must also arrange their sermons in a way that is easy for hearers to follow with a clear introduction, main portion, and conclusion, Helm said. The introduction and conclusion should take up about 10 percent each of the sermon, while the main body should occupy at least 80 percent of the preacher’s time, he said.

“Arrangement is best done when the outline mirrors the organization of the text,” he said. “The persuasive preacher intentionally arranges his sermon to make an argument.”

Helm defined expositional preaching as having taken place when “the shape and emphasis of the sermon is joyfully, rightly, submitted to the shape and the emphasis of the text. It’s that simple.”

Helm’s final lecture dealt with the preacher’s ethos, which he defined as “the indispensable attribute of credibility. When your hearers have bestowed on you credibility—they believe you.”

The persuasive preacher must cultivate credibility both in his person and in his preaching—his godly character and his sermon content, Helm said. Humility and godliness are foundational and non-negotiable for credibility in preaching. A preacher establishes credibility by demonstrating genuine humility in both his character and delivery.

Godly living and humility adorn the preacher with a clear conscience which becomes evident in his preaching, Helm said, referencing Paul’s advice to young Timothy in 1 Timothy 4:16: “Keep a close watch on yourself and on the teaching. Persist in this, for by so doing you will save both yourself and your hearers.”

“If you forfeit your conscience,” Helm said, “you forfeit the internal characteristic of credibility.”
