Yoo Ki-sung's Preaching Style: One Message, Walking with Jesus

The Preacher and His Context

Yoo Ki-sung is the senior pastor emeritus of Good Shepherd Church (선한목자교회) in Gwangmyeong, Gyeonggi Province, and the founding director of With Jesus Ministry. A graduate of Methodist Theological University, he served as senior pastor at Busan First Church and Ansan Gwanglim Church before voluntarily stepping down in December 2022 at age sixty-five — five years before his denomination’s mandatory retirement of seventy.

Yoo is among the most prolific writers in Korean Protestantism, with 119 titles registered under his name (93 print, 26 e-book) as of the most recent count. His central works — I Die and Live by Jesus (2008), Look to Jesus (named Book of the Year by Korean Christian publishers in 2014), and One Hour of Prayer (2019) — trace a consistent theological arc rooted in Galatians 2:20 and the theme of union with Christ.

A Deliberate Turn Toward Expository Preaching

The most explicitly narrated shift in Yoo’s homiletical development is his move from topical preaching to expository preaching. He frames this not primarily as a formal choice but as a change in his understanding of who is speaking from the pulpit:

“I came to the boldness of knowing that it is not my sermon but the Holy Spirit himself preaching through the Scriptures.”

In his telling, the earlier topical-preaching years corresponded to a period in which he understood the gospel mainly as a doctrine of atonement — something he recognized as incomplete while serving as a military chaplain. When he came to see that the gospel entailed not only forgiveness of sins but the believer’s union with the risen Christ (Galatians 2:20), his preaching method followed suit: the biblical text, rather than a thematic agenda, became the frame through which each sermon moved.

This theological reorientation is also what draws him toward Pauline letters on union and indwelling (Romans 6–8; Galatians 2; Colossians 1–3) as recurring sermon territory.

The Single-Message Principle and Rhetorical Craft

One Sentence Is Enough

The most immediately recognizable structural feature of Yoo’s preaching is what he calls the single-message principle. He has stated plainly that “even three main points are too many,” and defines a successful sermon as one in which “a single sentence stands out clearly in the minds of the congregation when the service ends.” Rather than organizing a sermon around several parallel propositions, his design concentrates the whole delivery on making one thing land.

This discipline shapes the expository process from the inside out. Even when a text carries multiple threads, the preacher’s task is to identify which thread becomes that session’s message, and to arrange everything else — context, illustration, application — in service of it.

Anaphora as Reinforcement

To anchor the single message in memory, Yoo makes conscious use of anaphora — the deliberate repetition of a key phrase at intervals throughout the sermon. He has cited Martin Luther King’s “I Have a Dream” as a formative reference, noting that he came to understand “how much power repetition carries.” The target of each repeated phrase is the same one-sentence core, restated in slightly different registers until it settles into the listener’s interior.

Challenging Questions and Paradox

Rhetorical questions appear frequently in his sermon transcripts: “Do you truly believe that Jesus is with you right now?” or the more pointed paradox, “If Jesus lives in my heart, how can a fight between spouses even happen?” These questions are not rhetorical in the dismissive sense — they function as diagnostic instruments that invite the listener to compare the theological claim being preached with the texture of actual daily experience.

The Emotional Transfer Principle

Yoo describes his own internal state as a necessary precondition of effective preaching. His preparation aims to generate “tears and an urgency that cannot stay silent” before he steps into the pulpit. He explicitly references Bill Hybels’s “So what?” test — asking whether each element of the sermon lands on actionable ground — and uses it as a self-check during preparation. The movement from the preacher’s inner conviction to the congregation’s response is a designed structure, not a byproduct.

The Jesus Walking Journal and Its Connection to the Pulpit

No analysis of Yoo’s preaching makes sense without the Jesus Walking Journal movement (예수동행일기), which he began in 2010 and which has since spread to churches across Korea and abroad. The origin was personal: at a point when the church was growing outwardly, he records asking himself whether the Lord was genuinely present within him. Drawing on inspiration from Frank Laubach’s writings on the practice of the presence of God, he began keeping a daily log of his awareness of Jesus throughout the hours of the day. In 2011, during a sabbatical month, he and his wife kept the journal together — and the resulting change in his experience led him to extend the practice to the whole congregation.

The method has four components: daily written log of awareness of Jesus from morning to sleep; sustained attention throughout the day, grounded in Hebrews 12:2 (“Let us fix our eyes on Jesus”); communal sharing of journal entries for mutual encouragement; and theological accountability to guard against subjectivism and spiritual pride.

The link to preaching is direct. Yoo identifies stories from his own daily experience as the most powerful sermon illustrations he uses. “When I testify during a sermon to what the Lord has done in my ordinary life,” he has said, “the most remarkable things happen in the congregation.” The journal, then, functions as a source repository for the personal testimony that forms the backbone of his illustrative material.

Preparation Routine

Yoo’s weekly preparation follows a structured pattern documented in materials shared publicly. He begins on Monday with multiple readings of the text and prayer — specifically asking, “What would Jesus say here, and how would he say it?” Across the week he reads three to four books while allocating approximately twenty hours to sermon preparation, followed by a night of prayer before the final draft. On Saturday mornings, the full pastoral staff gathers to read the sermon manuscript together and offer critique, flagging items such as “dry enumeration of Scripture,” “doctrinal rigidity,” and “disconnection from real life.”

His manuscript-writing practice is likewise deliberate: he writes while reading aloud, imagines a single specific person seated in front of him to whom he is explaining something, and keeps sentences as short as the content will allow. This produces a conversational rather than declamatory register — the text sounds spoken because it was composed for speaking.

Academic and External Reception

The Jesus Walking Journal movement has attracted scholarly attention. Yoo Jae-kyung of Yeungnam Theological University published a KCI-indexed study, “The Spirituality Diary from the Perspective of Christian Spiritual Formation,” in Theology and Praxis (vol. 57, 2017), evaluating the practice positively as a catalyst for spiritual growth and tracing its affinity with Puritan devotional tradition. Systematic theologian Chung Seong-wook of Denver Seminary has analyzed the Jesus Walking practice through the lens of systematic theology categories — theology proper, Christology, soteriology, ecclesiology, and eschatology — in academic conferences organized around the movement.

A measured critical voice came from missiologist Heo Seong-sik (Ph.D., Princeton Theological Seminary), who in a 2016 essay in Newsnjoy invoked Lesslie Newbigin to caution that exclusive inward attention to the Lord’s presence might “ghettoize and privatize faith.” Yoo’s response has been consistent:

“As people build up their personal spirituality, the fruit that first appears is caring for the poor and the marginalized.”

Whether personal and social dimensions of faith reinforce or compete with each other is a longstanding conversation in Korean Protestantism, and Yoo’s movement has made that conversation concrete.

Homiletical Profile

Yoo Ki-sung’s preaching stands in the pietist stream of Protestant spirituality — formally aligned with expository practice, but oriented not toward the objective exegetical display of biblical content but toward its subjective uptake in the hearer’s inner life. Original-language analysis and historical-critical context play a minimal role; the governing question is whether the text is being genuinely experienced, not merely understood.

His own summary — “I came to know that simply preaching is not enough” — captures the integrated logic of his homiletical project. Preaching, for Yoo, is the entry point into a larger ecosystem that includes daily journaling, communal accountability, and ongoing spiritual attention. The sermon does not stand alone; it is the week’s public articulation of what the congregation has been practicing in private, and an invitation to practice it more fully in the days ahead.
