Ok Han-heum's Preaching Method: Where Expository Preaching Meets Discipleship Training

Ok Han-heum (1938–2010) founded Sarang Community Church in Seoul and built what became the most influential lay-discipleship model in Korean Protestantism — so widely adopted that “discipleship training” in Korean church circles is almost synonymous with his name. Scholarship on his preaching converges less on what he preached than on how he built and delivered a sermon — a method worth examining on its own terms.

Structure: book-by-book exposition anchored to a single idea

For decades Ok preached verse-by-verse through entire books — three volumes on Romans, three on John, two on Acts, two on the Sermon on the Mount. The Called2Awaken Disciple-Making Ministry International released an eleven-volume expository collection in 2020, the tenth anniversary of his death, documenting the scale of that output.

Kwon Ho, a homiletics professor at Hapdong Theological Seminary, summarized Ok’s compositional discipline in a 2024 Eunbo Forum paper: he “did not try to convey many ideas in a single sermon, but only one central idea.” That discipline sits close to Haddon Robinson’s “Big Idea” school of expository preaching — finding the text’s single controlling thought and building the entire sermon toward it, rather than moving through a checklist of observations.

Composition process: from principle to audience

Kwon’s paper identifies a three-stage process behind Ok’s sermons:

1. Identify the text’s central point
2. Principle — restate that point in contemporary language
3. Audience application — spell out how the principle lands differently across distinct groups within the congregation

Kwon calls Ok’s grasp of homiletical “relevance” striking, given that “hermeneutics and homiletics theory on this subject had barely been introduced to the Korean church” at the time. That three-stage process is why scholars repeatedly note that even full-book exposition, in Ok’s hands, landed as if it had been written “for me, today” — the feature that set it apart from expository preaching that stops at exegetical explanation.

A five-step composition process compiled by the Youth Ministry Research Institute fills in more detail: select the text, do the scholarly exegetical work, listen to respected preachers (Korean and international), organize the message, then revise it from the listener’s vantage point.

Emphasis: confessional ethos, application, and discipleship

One of the most consistently noted features of Ok’s preaching is a confessional ethos — he did not hesitate to disclose his own emotions, personal experience, even moments he found embarrassing. Multiple studies trace a direct line from that self-disclosure to a felt psychological connection between preacher and congregation.

That emphasis on application is inseparable from his larger pastoral philosophy. Kim Dae-hyuk, a professor at Chongshin University, cites Ok’s own formulation at a 2024 Eunbo Forum session: “evangelism without discipleship training is a sandcastle.” Kim reads Ok’s evangelistic preaching as “text-respecting, and incarnational in that it makes concrete, life-oriented application for its listeners.” Sermons fed directly into small-group discipleship training, which in turn produced the lay leaders who ran those groups — preaching, small groups, and leadership formation as one connected pipeline rather than separate ministries.

Use of the biblical languages and background study: concentrated in preparation

Because “scholarly research” is an explicit step in Ok’s five-stage composition process, original-language exegesis and commentary work were a required part of sermon preparation. But the analyses converge on a second point: that research rarely surfaced in the pulpit as grammatical explanation or exegetical argument. It was reprocessed into the language of application and everyday life before it reached the congregation.

Kim Dae-jo, who studied expository preaching at the London School of Theology, draws a direct comparison in his book Learning Expository Preaching from John Stott and Ok Han-heum: Stott’s strength lay in “text-centered, logical analysis,” while Ok’s lay in preaching that “touched the hearts of the congregation” through application. Kim also notes that Ok’s “exegetical rigor was thinner than Stott’s” — better read as evidence of where Ok’s center of gravity sat (communicative application over exegetical precision) than as a simple deficiency.

A spectrum of assessment

Park Eung-kyu, a professor at Asia United Theological University, categorizes Ok as a “practical reformed theologian,” crediting him with “an exceptional ability to reinterpret ordinary truths of Scripture and church history into a theology for the church.” A more critical line of assessment — from press coverage rather than peer-reviewed scholarship (Newsnjoy, 2010) — argued his preaching “never fully overcame a dualism, remaining centered on individual faith.” The difference in venue, academic journal versus religious press, matters for weighing the two claims.

What’s more interesting than the disagreement itself is what both readings assume in common: that Ok’s preaching took the form of book-by-book exposition while keeping application and life change as its center of gravity — the same structural observation from two different evaluative angles.
