Unity in Diversity
Thesis Christ actively reconciles and unites all things to himself, making unity in diversity possible both in the world and within the individual believer, and this harmonizing work requires our deliberate surrender of every part of ourselves to his kingship.
The shape of the argument
42 units across exposition, application, illustration, theological claim, and conclusion. The pastor's argument is built from these moving parts.
- cultural reference · unit #9 — Uses the visualization of biblical cross-references to illustrate unity and diversity—diverse texts forming a unified, interconnected whole. The graphic serves as a visual analogy for the theological concept.
- analogy · unit #12 — Extended musical analogy: the world is like a box of untuned instruments that seem unrelated until a great tuner (Christ) appears and restores them to their original tonality. The chaotic pre-concert tuning becoming harmony serves as a vivid image of Christ's reconciling work over time.
- historical example · unit #17 — This is a composite unit containing exposition (OT prophecy of nations gathering), theological claim (Christ fulfills these prophecies), and extended illustration (Orwell's Spanish Civil War disillusionment). The Orwell story serves as a cautionary tale: secular humanism's attempt to achieve unity without Christ produces propaganda, betrayal, and chaos. The unit argues that unity in diversity is uniquely and exclusively possible through Christ.
- historical example · unit #37 — Uses Patrick of Ireland's prayer as a devotional model for total Christ-centeredness. The quotation illustrates what it looks like to have all of life unified around Christ, and Oswald frames it as normative saintly practice, not novelty. This serves both as illustration and indirect exhortation.
- historical example · unit #38 — Uses Jonathan Edwards's personal covenant renewal as a second devotional model, this time with more explicit language of total surrender. The Edwards quotation is longer and more legally precise (cataloging body parts, senses, faculties) and serves as a template for the rededication Oswald is calling the congregation to make. The aside about men's tempers is pastoral aside embedded in the illustration.
- Even secular cultural figures are recognizing that Christianity is the foundation of Western civilization and that the West cannot survive without it. unit #1
- Christ himself—not merely Christian ideas—actively and invisibly transforms the world by persuading people to faith and obedience. unit #3
- Unity and diversity is a fundamentally Christian idea that governs all of life and would not exist without Christ teaching it to the world. unit #7
- Christ's reconciling work is best understood as a reharmonization—restoring many things to unity, as Leibniz described harmony. unit #10
- The King who unifies the nations is uniquely qualified because he is the Lamb—a crucified King who demonstrates that servanthood and sovereignty are not in tension. unit #20
- Unity is produced when all peoples worship Christ as worthy and learn leadership from him, resulting in societal good. unit #21
- Jesus unifies diverse peoples by gravitational pull—they remain distinct (different languages, foods, values) but are aligned by their shared worship of him, which is miraculous compared to secular humanism's false uniformity. unit #32

"Early in life, I have noticed that no event is ever correctly reported in a newspaper. But in Spain, for the first time, I saw newspaper reports which did not bear any relation to the facts, not even the relationship which is implied, an ordinary lie. I saw great battles reported where there had been no fighting and complete silence where hundreds of men had been killed. I saw troops who had fought bravely, denounced as cowards and traitors, and others who had never seen a shot fired, hailed as heroes of imaginary victories. And I saw newspapers in London retailing these lies and eager intellectuals building emotional superstructures over events that never happened." — George Orwell (unit #17)
"Christian activist literature he writes too often reduces or even perverts Christianity into an ideology, a set of ideas. Christianity is not, however, an ideology to be implemented through crusading activism. Rather, Christianity is a new creation. It grows holistically and organically out of the life of faith and prayer. It is as men draw near to God and acquire wisdom and maturity from the Scriptures that they are built up and prepared for dominical responsibilities, and God will confer these upon his people in due time." — James Jordan (unit #35)
"Christ with me, Christ before me, Christ behind me, Christ in me, Christ beneath me, Christ above me, Christ on my right, Christ on my left, Christ when I lie down, Christ when I sit down, Christ when I arise, Christ in the heart of every man who thinks of me, Christ in the mouth of everyone who speaks of me, Christ in every eye that sees me, Christ in every ear that hears me." — Patrick of Ireland (unit #37)
"I have this day solemnly renewed my baptismal covenant and self dedication, which I renewed when I was taken into the community of the church. I have been before God and have given myself all that I am and have to God, so that I am not in any respect my own. I can challenge no right in this understanding, this will, these affections which are in me. Neither have I any right to this body or any of its members. No right to this tongue, these hands, these feet, no right to these senses, these eyes, these ears, this smell or this taste. I've given myself clear away and have not retained anything as my own." — Jonathan Edwards (unit #38)

0 · Oswald opens by situating the sermon as the conclusion of a series on how Christ has already transformed the world
And if you'll open your Bibles to the Book of Revelation, chapter 7 this morning, we'll be in Revelation, chapter 7, verses 9 through 10. Now we're concluding a series that's been. I don't know, I just have found it a great fun to work through. The series has been entitled Let Earth Receive Her King. And we've essentially just been working through sort of evidence in history that Jesus has changed the world already and is continuing to change the world. And one of the phrases that we've used to describe this is something John Newton used to describe his own Christian life. He's like, I am not what I should be. I'm not what I would like to be, but by God's grace, I am not what I used to be. And we have been looking at the consequences of the Incarnation and the effects of the Incarnation on the whole world. And today is the final sermon in this series. People. The basic idea that we've been working through is something I call moral history. It's just looking back through the development of the values we take for granted today and to see their fundamentally Christian roots.
1 · Establishes cultural credibility for the claim that Christianity is foundational to Western civilization by citing contemporary secular voices (Zuby and Elon Musk) acknowledging Christianity's indispensable role
And people are beginning to wake up to the key role that Christianity has played in the development of our world. A guy that I'd never heard of. Some of you are going to know who this is. A guy named Zubi. He's a British rapper and podcaster. Y' all know, some of you should. I think I'm cooler than some of you. Daryl Dean knows who Zubie is, and I'm not okay with this. Anyway, one day he rather innocently tweeted, I don't think I've ever said this publicly and directly, but I think the west is absolutely screwed if it loses Christianity. It's like removing the foundations of a building, but pridefully expecting it to remain forever. And Elon Musk retweeted, I think you're probably right.
2 · Introduces Tom Holland's Dominion as the primary scholarly authority for the series' moral history approach
We've been working through various books that have been dealing with this idea. And I mentioned a few weeks ago the that Tom Holland's book Dominion is probably the most popular of these books. And as the introduction to his book, he writes for a millennium and more. The civilization into which I was born, into which I had been born, was Christendom. Assumptions that I had grown up with about how a society should be properly organized and the principles that it should uphold were not bred of classical antiquity, still less of human nature, but very distinctively of the civilization's Christian past. So profound has been the impact of Christianity on the development of Western civilization that it has come to be hidden from view. It is the incomplete revolutions which are remembered. The fate of those which triumphed is to be taken for granted. The ambition of dominion is to trace the course of what one Christian writing in the third century A.D. termed the flood tide of Christ. How the belief that the son of the one God of the Jews had been tortured to death on a cross came to be so enduringly and widely held that today most of us in the west are dulled to just how scandalous it originally was. This book explores what it was that made Christianity so subversive and disruptive, how completely it came to saturate the mindset of Latin Christendom, and why, in a West that is often doubtful of religion's claims, so many of its instincts remain, for good or for ill, thoroughly Christian.
3 · Oswald pivots from Holland to assert his theological correction: it is not Christian ideas that transform the world, but Christ himself actively at work
Now, my additional contention in this series is that I want to separate from Holland's idea in one particular respect, and that is, is that Holland seems to think it is the ideas of Christendom that have changed the world. And I would say, no, it's Christ that has changed the world. I would. I would be with Athanasius, who we saw this last week, for now, Athanasius writing in, like 320 A.D. or so, for now, that the Savior works so great things among men and day by day is invisibly persuading so great a multitude from every side, both from them that dwell in Greece and in foreign lands, to come over to his faith and to obey his teaching.
4 · Introduces the concept of 'narcissism' (narcissistic exegesis) to diagnose the problem of self-centered Bible reading that misses the Bible's emphasis on Christ's active work in the world
So Holland seems to put forth that this is just generic gospel ideas that are changing the world. Like, nope, this is Christ who is actively seeking and saving the lost, and he is actively doing a work that the Bible describes actually quite thoroughly. We just tend to overlook these particular passages. Have you ever heard the phrase or the word narcissist? It's the combination of narcissism and exegesis. And essentially it's when you go to your Bible and you're looking for you, right? But if you take a moment and just hit pause and just look at what the Bible's actually saying, so much of it has to do with this idea that, that Jesus is actively at work in the world in general. We used to try to tell people years ago, you know, we were pastoring, a lot of young people, we'd say, listen, Jesus loves you. He just doesn't love only you. And a lot of the glory that is out in the world to observe is to see Jesus loving others, not just you. And so we escape from this narcissist and do actual exegesis. And we see that Christ has been at work and is at work in the world. It isn't just the ideas of the Gospel that is shaping the world. It's Christ himself. This lines up perfectly with what the Bible teaches. In Ephesians 2:17, for instance, he came and preached peace to you who were far off and peace to those who were near. It's Jesus doing the converting, not. Not the idea of Jesus. It's Jesus doing the converting.
5 · Introduces the Pauline language of 'reconciling' from Colossians 1:19-20 to describe Jesus's work
This idea is communicated elsewhere by Paul as reconciling. Jesus is reconciling the world to himself. For instance, at the t end of that great Christological passage in Colossians 1, we're told in Colossians 1:19. For in him the fullness of God was pleased to dwell, and through him to reconcile to Himself all things. All things, whether on heaven or on earth, making peace by the blood of his cross.

6 questions for your group this week
-
In Revelation 7:9, John describes a multitude from every nation, tribe, people, and language standing before the throne. What strikes you about the fact that this unity includes diversity rather than erasing it—that people remain distinct in their origins and cultures even as they worship together?Revelation 7:9→ How does this vision challenge the way the world typically pursues unity—through sameness or conformity—versus the way Christ produces it?
-
The sermon emphasizes that Christ reconciles not through force or coercion, but through a kind of 'gravitational pull'—people are drawn to worship him and remain aligned by that shared allegiance. Where have you experienced or witnessed this kind of willing, joyful unity in your own relationships or church community?
-
According to the sermon, the Lamb—a crucified King—is uniquely qualified to unify diverse peoples because his death demonstrates that servanthood and sovereignty are not in tension. How does this reshape what you thought leadership and authority were supposed to look like?Revelation 5:9-10→ Where in your own life do you feel the tension between wanting to lead and wanting to serve, and how might Christ's example reharmonize that for you?
-
The sermon identifies a fallen condition we all face: we are internally diverse, with competing desires and appetites pulling us in different directions. How do you experience this inner disharmony, and what typically happens when you try to resolve it through your own effort?Romans 8
-
The gospel addresses this internal fragmentation by having Christ harmonize all of you into unified worship of him. What would it look like this week to invite Christ into that work—to let him align your competing desires around worship of him rather than around other goals?→ Can you name one area of your life where you sense Christ calling you to this kind of reharmonization?
-
The sermon teaches that unity in any relationship—marriage, family, church, or society—requires a shared way of handling sin through the gospel. In a relationship that matters to you, where might a lack of gospel-centered repentance and forgiveness be fragmenting what could otherwise be unified?Ephesians 2:17→ What would it look like to invite that person or group into a shared commitment to handle conflict through the gospel rather than through blame, distance, or defensiveness?
5-day reading plan
This week we trace how Christ's reconciling work creates unity across all diversity—from cosmic reharmonization to the internal harmonizing of our own competing desires.
Paul describes the fullness of God dwelling in Christ and reconciliation accomplished through His blood—not merely spiritual peace, but a cosmic reharmonizing of all things. This passage roots the sermon's central claim: Christ doesn't simply bring ideas of unity; He actively restores creation's fractured harmony through His person and finished work. We grasp the magnitude of His reign when we see reconciliation as nothing less than the restoration of all things to their proper alignment under Him.
God's plan of grace, revealed and made known through Christ, is to gather all things under His headship—an economy of unity that shapes both heaven and earth. The language of 'gathering' and 'bringing to fullness' suggests not coercion but the gravitational pull of Christ's worthiness drawing diverse peoples into alignment. We see here that worldly transformation flows not through political machinery but through the revelation of Christ as Lord, by which people are persuaded to orient their lives toward Him.
The redeemed from every tribe, tongue, people, and nation sing a new song, declaring Christ worthy because His blood ransomed us for God—and they become a kingdom and priests serving our God. This passage shows that unified diversity is born not from shared ethnicity or politics, but from shared worship of Christ and participation in His priestly, reigning purpose. Our leadership model, our value system, our very identity are reoriented by beholding His worthiness and following His example of sacrificial sovereignty.
Christ came and preached peace to those far off and those near—breaking down the wall that separated Jew from Gentile through His proclamation of reconciliation. The gospel itself is the message of how sin is handled: Christ bore it, satisfied justice, and opened a way for all peoples to belong to one family. Without this shared understanding of sin's gravity and Christ's sufficiency, no true unity can exist; with it, even ancient enmities dissolve in the presence of His grace.
Though our sins are like scarlet, God invites us to reason together—implying that our internal disorder, our conflicting loyalties and appetites, can be brought into alignment through honest encounter with His grace. The Christian life is not the elimination of diversity within us, but the miraculous reharmonization of all our competing desires, fears, and loves under the gravitational pull of Christ's worthiness. As Christ unifies nations through worship, so He unifies each of us by making His glory the center around which every appetite and ambition finds its proper place.
Prayer for Christ-Centered Unity
Father, we adore you for sending your Son, the crucified King whose sovereignty and servanthood are perfectly one, who alone has the authority and the heart to harmonize the diverse peoples of the earth around himself. We confess that we often seek unity through coercion, through the force of our ideas or the pressure of our preferences—forgetting that true unity flows not from uniformity imposed, but from many distinct voices aligned by shared worship. We confess, too, that within ourselves we are divided: competing desires war within us, and we lack the internal harmony that marks a life fully surrendered to Christ's lordship.
Yet in the gospel we have seen what Christ accomplishes: he reconciles us to God through his blood, and in doing so he reharmonizes all things broken by sin—restoring us not into sameness, but into a glorious diversity held together by allegiance to him (Colossians 1:19–20). He stands as the Lamb enthroned, drawing all nations to worship him as worthy, and his gravitational pull gathers peoples from every language, tribe, and nation without erasing the beauty of their distinctiveness (Revelation 7:9–10).
We pray that you would grant us the grace to pursue unity in our marriages, families, and church by means of the gospel—learning together how to handle sin with humility and restoration, always pointing one another to Christ's finished work. Form us into people whose deepest desire is Christ's lordship over all our competing appetites, so that we become living evidence of his power to reconcile and transform. And move through our witness—not through our activism, but through our faithful proclamation of Christ—so that individuals are converted and drawn into the worshipping community of his kingdom.
To him who loved us and gave himself for us, who reigns now and shall reign forever over a unified, diverse, redeemed humanity—be all glory and honor, now and always.
Different People, One King
Chris talked about how Jesus brings people from every language and culture together—not by making them all the same, but by making them all worship him. Use this prompt to help your family see that real unity doesn't erase our differences; it centers them on Jesus.
In the sermon, Chris described how people from different countries, languages, and cultures can all worship Jesus together while staying who they are—like an orchestra where every instrument sounds different but plays the same song. Can you think of a time when you've seen people who are really different from each other work well together? What made that work? How is that like what happens when different people follow Jesus?
Unity Through Worship of Christ
- What struck you most about how Christ actively unifies diverse peoples—not by erasing our distinctiveness, but by drawing us together in shared worship of him?
- In our marriage, where do we need to let Christ's reconciling work reshape how we handle our differences or work through conflict—particularly, are we inviting him to reharmonize areas where we're pulling apart?
- What is one way you sense Christ calling you toward greater internal unity—harmonizing your own competing desires around worship of him—and how can I pray for that transformation in you this week?
Revelation 7:9
After this I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands.
Why this verse: This verse is the primary text of the sermon and crystallizes its central claim: Christ unifies diverse peoples across all nations, tribes, and languages in shared worship. It anchors the theological reality that unity and diversity—not uniformity or division—is the eschatological goal and present reality for those transformed by Christ's reconciling work.
