Pastor Lee Sang-jun leads 1516 Church, whose YouTube channel (@1516church) publishes Sunday sermons in both Korean and English. He spent a full year preaching through 1 Samuel, then moved to 1 Timothy — where, as of mid-2026, the series has reached chapter five across more than thirteen sermons. This profile draws on subtitles from ten sermons preached between March and June 2026 and examines his preaching across four dimensions: structure, theological emphasis, illustration, and congregational method.

Book by Book: The Architecture of Sustained Exposition

The organizing principle of Lee’s preaching is sequential exposition through entire biblical books. He does not select passages by topical theme or seasonal liturgy. He begins at the opening verse and moves through a book until it is finished — a discipline he apparently practices across years. References in the 1 Timothy series to the prior year in 1 Samuel (“We spent a whole year on 1 Samuel together, you remember”) make clear that the congregation carries this accumulated reading as shared memory.

Each sermon follows a consistent internal structure: the passage is read aloud with the congregation, then situated in its historical and cultural world, then interpreted for its theological meaning, then applied to present life with a specific pastoral address. The movement is deliberate and unhurried. In a sermon on the widow register of 1 Timothy 5, Lee spent considerable time explaining the social and legal status of women in the Roman Empire — the near-absolute authority of the male householder, the near-impossibility of economic independence for women without one — before turning to the contemporary implications for single mothers and women attending church without their husbands.

The Hebrew text is brought in when the argument requires it. Explaining Leviticus 19:32 (“Rise in the presence of the aged”), Lee noted that in the Hebrew, the command to honor the elderly and the command to fear God appear in parallel construction — a literary pattern that, in the biblical idiom, signals semantic linkage or near-synonymity. Honoring elders, he concluded, is not a cultural preference but belongs to the same field of meaning as fearing God.

Perseverance over Optionality: A Recurring Theological Grammar

Across the sermons examined, a single theological conviction recurs in different registers: that in the domains that matter most — faith, marriage, vocation, leadership — perseverance is a greater virtue than optionality.

The argument appears most directly in the sermon on 1 Timothy 5:9-16. The phrase “wife of one husband” (applied to qualifying widows) becomes a launching point for a broader cultural observation: that contemporary life is organized around maximum switching options — phone plans replaced before the contract ends, jobs changed the moment conditions improve, marriages dissolved when satisfaction declines. “In the essentials of life,” Lee said, “constancy matters more than variability. Happiness doesn’t come from avoidance — it comes from commitment.”

The same logic governs his treatment of church leadership. In the sermon on 1 Timothy 3, the controlling example was Yi Sun-sin, the sixteenth-century Korean admiral who, after being stripped of his rank and sentenced to serve as an ordinary foot soldier, continued to risk his life in defense of his country. The title of the sermon — “Will you control, or be governed?” — already frames leadership as a question of interior disposition rather than formal authority. David fighting Goliath without a title, an unnamed mission-organization leader who declined ordination so that missionaries could address him informally, a church elder who became authoritarian after receiving a position he had previously held with gentleness: these examples cycle through multiple sermons to illustrate the same point from different angles. The office does not make the servant; the interior readiness must exceed the weight of the title.

Three Registers of Illustration

Lee draws illustrations from three distinct territories, often within a single sermon.

The first is contemporary popular culture. Smartphone upgrade cycles, the MZ generation’s job-hopping patterns, the unexpected national revival of trot music, the nostalgia series Reply — these appear without any sense of cultural condescension, as simply the shared world the congregation inhabits. Neuroscience makes several appearances: the claim that “didorphin” (a rarely-cited neuropeptide) is four thousand times more effective than endorphin is used to provide a physiological anchor for the joy of worship and the satisfaction of serving others. Dopamine addiction and its link to emotional flatness toward family and real life is invoked as a counterexample to the kind of joy the Holy Spirit produces.

The second is pastoral memoir. Lee speaks from experience gained in Vancouver, where he served before his current ministry. Two stories recur. In one, he describes watching how immigrant Korean teenagers with parents present in the congregation were treated with more respect by church adults than teenagers who had come alone as international students — an observation that becomes his entry point into the New Testament’s concern for the widowed and unprotected. In the other, he describes taking over a Tuesday prayer meeting that had dwindled, deciding unilaterally to extend it from ninety minutes to three hours, and watching attendance triple to two thousand people over the following months. A youth missionary training program — where single participants were required to reach conversational-level Arabic or Mandarin within two months, through daily memorization of a hundred vocabulary items — is described as producing hundreds of missionaries and restoring the confidence of young Koreans in the vitality of the gospel.

These are not offered as cautionary tales or as credentials. They function as evidence for a theological claim: that the gospel, presented at full strength rather than diluted for palatability, actually works.

The third register is the biblical world itself — described in enough historical detail to make the original readers’ situation vivid. The Roman patria potestas, under which all family members and their property belonged to the male head of household; the theological genre of “widowhood” in the Old Testament, where care for widows, orphans, and strangers was a structural feature of covenant community; the identification of Lydia, the dealer in purple cloth who hosted the Philippian church, as probably a single household head — these contextual observations are deployed not as historical curiosity but as the explanatory frame through which the congregation hears the text as addressing something real.

A Participatory Pulpit

The most immediately noticeable feature of Lee’s delivery is how thoroughly it incorporates the congregation into the act of preaching.

Read-alongs are standard. “Let’s read this together,” “Say it after me” — these invitations appear multiple times in a single sermon. The congregation is not a passive audience receiving completed interpretation but a group walking through the text in real time. Questions are put directly: “What was David’s father’s name? Right — Jesse.” “What’s the first commandment about human relationships? Right — honor your father and mother.” The effect is not quiz-show participation but a kind of communal retrieval of shared biblical literacy.

Humor serves a structural function. The observation that the congregation was responding with “Amen” from only one section of the seating — “You need to do it on both sides, actually” — arrives in the middle of a sermon on marriage fidelity and releases something in the room while also marking the emotional register of the moment. A passing reference to a particular congregant who complained about being called “grandmother,” the footnote that informally calling a newly ordained staff minister by her former title would incur a fine — these small detonations keep the long sustained arc of an expository sermon from becoming lecture.

Lee also practices pastoral transparency with his own interior life. He describes himself as constitutionally introverted, someone who spent years managing conflict by tolerating it on the outside while churning on the inside — “spending days unable to sleep, constructing elaborate scenarios, then walking in and having the words come out completely differently.” He frames this not as a failure mode but as a pattern God corrected by showing him that performed patience over internal fury is a form of hypocrisy rather than virtue. The congregation is not primarily learning about their pastor. They are being given permission to recognize the same pattern in themselves.

The Density of Sourcework — Original-Language Observation Fused with Historical Background

Lee Sang-jun’s exposition gains its texture from combining close observation of the Hebrew text’s syntax with historical and cultural background research. In his sermon on Leviticus 19:32 (“Rise in the presence of the aged”), the observation that in Hebrew idiom two commands placed in succession signal semantic linkage or near-synonymity becomes the basis for reading “honor the elderly” and “fear God” as belonging to the same conceptual field — a method that treats a syntactic feature of the original language as the starting point for theological argument, not an incidental detail.

Historical background research operates with the same density. The Roman patria potestas, under which a father held near-absolute legal authority over his household; the early church’s register of widows (1 Timothy 5) and the office of widow-ministers; the observation that Joseph, Jesus’s father, disappears from the biblical narrative once Jesus turns twelve — these details support a reading of Mary as, in effect, a single mother. Background research of this kind does not remain mere scene-setting. It functions as a tool for translating the text’s unfamiliar social world into images a contemporary congregation can grasp concretely.

This method is bound up with the recurring expository structure — read the text, situate it historically and culturally, interpret it theologically, apply it to present life (see “Book by Book” above) — that recurs sermon after sermon. Because the original language and background material function as the grounds of interpretation rather than introductory ornament, exegetical work forms the very skeleton of how Lee Sang-jun composes a sermon.
