Why Christian Unity Matters in a Divided World
Jesus’ prayer in John 17 is one of the most poignant and powerful moments in Scripture. On the threshold of his suffering and death, Jesus turned his heart not only toward his disciples but also toward all who would believe in him through their message—that is, toward us. With the weight of the world on his shoulders, he prayed:
"I ask not only on behalf of these but also on behalf of those who believe in me through their word, 21 that they may all be one. As you, Father, are in me and I am in you, may they also be in us,[a] so that the world may believe that you have sent me.22 The glory that you have given me I have given them, so that they may be one, as we are one, 23 I in them and you in me, that they may become completely one, so that the world may know that you have sent me and have loved them even as you have loved me.” (John 17:20-23)
This prayer reminds us that our unity as followers of Christ is not just a theological idea; it’s a testimony to the world. When we come together across denominational lines, we demonstrate that the love of Christ transcends our differences. In a world fractured by division, our unity can shine as a beacon of hope, pointing to the One who reconciles all things.
The Church is beautifully diverse. Across the globe, Christians worship in different languages, with different styles, and through different cultural expressions. Even within denominations, there are rich variations in theology, liturgy, and ministry. These differences are not obstacles to overcome; they’re gifts to celebrate! They reflect the creative work of God and the depth of God’s kingdom.
However, in practice, this diversity can sometimes lead to division or isolation. Congregations and ministry leaders may focus inward, prioritizing their own traditions or communities over the greater mission of the Church. It’s easy to become so absorbed in our own ministries and practices that we lose sight of the broader body of Christ.
But Jesus didn’t pray for sameness; he prayed for oneness. Oneness doesn’t mean abandoning our distinctives or erasing our differences. Rather, it means centering ourselves on Christ and his mission. It means recognizing that while we might worship differently or emphasize different aspects of theology, we are united in our shared confession: “one Lord, one faith, one baptism” (Ephesians 4:5).
This kind of unity requires humility. It calls us to lay aside pride and assumptions about “doing it the right way.” It invites us to listen, to learn, and to appreciate the beauty in other traditions. Unity means working together for the sake of the kingdom—amplifying our shared witness and serving as one body to bring healing and hope to the world.
What might this look like in practice?
Partnering with other churches in your community for shared worship, outreach, activism, or service projects.
Taking time to learn about other Christian traditions, not with a critical eye, but with a spirit of curiosity and appreciation.
Inviting speakers or worship leaders from other denominations to share in your ministry context.
Joining a local network of church leaders from vairous denominational and non-denominational churches (don’t have one? start one!)
Recommitting to prayer, asking God to soften our hearts and align our efforts with God’s will for unity.
Focusing on the aspects of our faith that are the same - like the Nicene Creed (we’re talking more about that this week over here).
Unity as Witness
The stakes are high. Jesus linked our unity directly to the world’s belief in him. When we are divided, we risk obscuring the gospel’s power (we really don’t have to look far to see that happen around us). But when we embrace our shared identity in Christ and work together, we offer the world a powerful picture of the reconciling love of God.
As we reflect on Jesus’ prayer, let us also make it our own:
"Lord, make us one. Teach us to see beyond our divisions and recognize your Spirit at work in one another. Help us to celebrate the beauty of your Church in all its forms and to work together for the sake of your kingdom. May our unity reflect your love and draw others to you. Amen."
Let’s commit to moving closer to one another in humility, love, and shared mission. The world is watching, and our unity proclaims Christ’s power to reconcile and restore. Will you join in this work?
