The unity of believers, modeled on the Trinitarian union, as a witness to the world.
Historical Context
Jesus' High Priestly Prayer, interceding for future believers during his farewell discourse, emphasizing the divine desire for the Church's oneness and its missional purpose.
Why It Matters
In a world marked by divisions and fragmentation, this sermon underscores that Christian unity is not merely an optional virtue but an essential, theological, and missional imperative. It reveals God's design for the Church to reflect the divine community and powerfully testify to Christ's sending and love.
Sermon Analysis
Central Thesis
Christian unity, rooted in the Trinitarian relationship and empowered by shared glory, is an ontological reality and an apologetic witness designed to persuade the world of God's sending and love.
Core Problem
The Church often struggles with disunity, treating oneness as an organizational achievement or an internal comfort, thereby hindering its witness and obscuring God's design.
Key Insight
Jesus' prayer for unity in John 17 is not for mere organizational sameness, but for a dynamic, participatory, and qualitative oneness — a 'lived theology' modeled on the Father-Son relationship, which becomes the compelling evidence for the world to believe in Christ.
Kingdom Implications
The sermon posits that true Christian unity is a direct manifestation of God's Kingdom on earth, reflecting the divine community and serving as the primary apologetic for its truth claims. This unity moves beyond internal cohesion to an outward-facing witness, drawing the world to believe in God's love and sending.
Practical Application
The sermon calls for concrete practices such as creating 'Ubuntu groups' for intentional mixed-space fellowship, committing to seasons of reconciliation, launching shared mission ventures, and fostering theological formation centered on Trinitarian indwelling. These actions cultivate unity as a lived reality and a missional strategy.
The Dialectical Movement
Thesis
Jesus prays for a profound unity among believers, modeled on the intimate union of the Father and the Son, intended to be ongoing and dynamic.
Antithesis
Despite this divine intention, the Church frequently experiences disunity, often reducing unity to superficial agreement or organizational alignment, which compromises its witness to the world.
Synthesis
True Christian unity is a shared reality and participatory glory, where believers, though diverse, are intimately connected through mutual indwelling in the Trinity, demonstrating a compelling apologetic that convinces the world of God's love and sending.
Transformation Point
The sermon moves the hearer from merely seeking internal cohesion to actively embodying a Trinitarian unity through practical actions — such as 'Ubuntu groups,' reconciliation, and shared mission — transforming their understanding of unity into a proactive, demonstrative, and missional way of being.

Key Lessons
Unity as Participation
Christian unity is not an enforced uniformity but a corporate invitation into the intimate, indwelling relationship of the Father, Son, and Holy Spirit. It is bestowed and sustained by communion with the Triune God, not manufactured by human programs.
Unity as Witness
The visible unity of believers serves as the Church's most compelling apologetic. A reconciled and united community persuades the world of God's sending and love, acting as an evangelistic sign that draws others to Christ.
Unity as Shared Glory and Transformation
The glory that the Father gave to the Son is shared with believers, making unity possible. This shared glory leads to maturity (teleioó), holiness, and mission, transforming the Church into a community that reflects God's character and serves sacrificially.
Leadership Insights
- Effective leadership fosters unity by grounding practices in robust theological teaching, specifically the Trinitarian nature of God and the concept of perichoresis.
- Leaders must actively create 'mixed-space fellowship' opportunities (e.g., Ubuntu groups) to intentionally bridge generational, cultural, and experiential divides within the congregation.
- Leading through conflict requires establishing clear practices for reconciliation, mediated conversations, and restorative justice, emphasizing humility and forgiveness.
- Missional unity is cultivated when leaders strategically partner with other congregations or community groups on sustained projects, making visible the Church's shared commitment to external service.
Reflection Questions
- How does our congregation currently define and pursue 'unity'? Does it align with Jesus' prayer for ontological and participatory oneness?
- In what ways are we actively reflecting the 'Ubuntu' principle—'I am because we are'—in our individual lives and corporate witness?
- What practical steps can I take this week to contribute to a deeper, more Trinitarian unity within my local church or community?
- How might our church's visible unity more powerfully serve as an apologetic for Christ in our local context?
- What specific areas of conflict or disunity in my life or church need intentional acts of reconciliation, facilitated by charity and truth-telling?
Legacy Impact
Rev. Dr. Tony Lloyd Lewis's sermon 'Lord Make Us One' leaves a legacy of profound theological clarity and practical challenge. It reorients the understanding of Christian unity from an internal, organizational goal to an ontological, Trinitarian reality with potent missional implications. Future generations embracing this teaching would prioritize deep, participatory communion over superficial agreement, recognizing unity as the Church's most compelling witness and a direct reflection of God's Kingdom. It inspires a Church that actively demonstrates its 'oneness' to a fragmented world, extending God's love and proving Christ's sending.
Connection to Kingdom Sermon Architect™
Thesis
The sermon's initial articulation of Jesus' prayer for unity among believers, drawn from John 17:20-23, serves as its Kingdom Sermon Architect thesis—an inspired theological truth from Scripture.
Antithesis
The KSA antithesis is revealed through the acknowledged reality of disunity within the Church and the common misconception of unity as mere organizational sameness. This directly contrasts with Jesus' profound prayer and the Trinitarian ideal.
Synthesis
The sermon synthesizes these two poles by presenting unity as a dynamic, participatory, and ontological reality, modeled on the Father-Son relationship, and actualized through shared glory. This re-framed understanding transforms unity into a powerful apologetic for Christ's sending.
Application
The KSA application is robustly demonstrated through the tangible 'Practical steps for congregational life'—such as 'Ubuntu groups,' seasons of reconciliation, and shared mission ventures—which bridge the theological insight with concrete, actionable steps for the congregation to embody this divinely desired unity.
