Paul is writing from prison, but he doesn't sound trapped. His circumstances are restricted, but his vision is enormous. Paul has been entrusted with what he calls a mystery—not a puzzle that only a few clever people can solve, but something that had been hidden and has now been revealed by God. The mystery is this: through Jesus Christ, Gentiles are welcomed fully into the family of God. They are “coheirs, members of the same body, and partners in the promise in Christ Jesus through the gospel” (Ephesians 3:6 CEB). That may sound familiar to us because we’re reading it nearly two thousand years later. But Paul understood how radical this was.

God’s saving purpose was bigger than anyone had imagined. Those who had once been considered outsiders were not being invited to stand at the edge of God’s people. They weren’t second-class members of the family. In Christ, they shared the inheritance. They belonged to the same body. They received the same promise. And Paul says this isn’t some last-minute adjustment to God’s plan. This was God’s purpose all along, now revealed and accomplished through Christ.

Then Paul takes it one step further. God intends for this wisdom to be made known “through the church” (3:10). Think about that for a moment. The church itself is meant to reveal something about God. Not only our preaching. Not only our worship services. Not only our statements of belief. Our shared life is supposed to tell the truth about what God has done in Christ.

When people who would normally be separated by background, ethnicity, culture, social position, history, or personality become one family in Jesus, the church becomes living evidence of the reconciling power of the gospel. That doesn’t mean Christian community will always be easy. Paul’s letters make it painfully clear that churches can struggle with division, pride, jealousy, conflict, and prejudice. But those struggles also reveal why Paul’s vision matters so much.

The church isn’t held together because we naturally fit together. We are held together by Christ. That means Christian unity is more than being friendly with people who already think, look, worship, vote, speak, or live like we do. The gospel creates a family whose deepest identity is found in Jesus.

Paul has spent the first half of the chapter describing this enormous purpose of God. Then he does something that might seem surprising. He kneels. “For this reason, I kneel before the Father…” (3:14). Paul doesn’t respond to God’s great mission by immediately developing another strategy. He prays.

He prays that believers will be strengthened through the Spirit. He prays that Christ will dwell deeply within them. He prays that they will be rooted and grounded in love. He prays that together they will begin to grasp the immeasurable dimensions of Christ’s love.

Then he asks that they would be “filled entirely with the fullness of God” (3:19). This is where God’s enormous purpose meets ordinary discipleship.

If the church is going to become the kind of community Paul has described, we need more than good intentions. We need the Spirit to strengthen us. We need Christ to shape us. We need the love of God to become the soil in which our lives are rooted.

Holiness isn't learning to appear more religious. It is the Holy Spirit forming the character of Christ within us so deeply that the love of Christ begins to shape how we live with one another. That kind of community becomes part of God’s witness to the world. And that brings Paul to the words many of us know best: “Glory to God, who is able to do far beyond all that we could ask or imagine by his power at work within us” (3:20).

We often hear that verse individually, as though Paul were encouraging us to dream bigger dreams for our personal lives. But Paul has spent three chapters talking about something much larger. God is creating a new humanity in Christ. Enemies can become family. Outsiders can become coheirs. Divided people can become one body. Ordinary believers can be filled with the love and presence of God. The church can become a living witness to the wisdom of God. That is the “far beyond” Paul has in mind.

And notice where the power is already working. “Within us.” God’s grace is not waiting somewhere in the distance for us to become impressive enough to receive it. The Spirit is already at work, strengthening, forming, reconciling, and drawing the church more deeply into the life of Christ.

Maybe our imagination needs to expand. Not because we need bigger personal ambitions, but because God’s purpose for the church is far greater than simply gathering once a week.

God is forming a holy people whose shared life reveals the reconciling love of Jesus. And by God’s grace, that work is already underway.

Read Ephesians 3:14–21 slowly today. As you pray Paul’s prayer, name one relationship or area of church life where you want Christ’s reconciling love to take deeper root. Ask the Holy Spirit to begin that work in you.
