God’s family is one household built on one foundation, but a foundation is only the beginning. God is not simply laying groundwork; he is placing stones on top of it and joining them together—and the stones are not identical. They are different shapes, different textures, drawn from entirely different quarries. This is the picture Paul opens up in Ephesians 2:21: “In him the whole structure, being joined together, grows into a holy temple in the Lord.”

Notice three small but significant terms: “in him,” “joined together,” and “grows.” Together, they tell us the church is not a pile of disconnected stones sitting near one another by coincidence. It is a structure being actively, intentionally assembled by a builder, and Christ is not merely underneath this building, propping it up from below. The whole structure exists “in him.” He is not only the foundation; he is the sphere in which the building itself takes shape.

Different Stones, One Builder

Paul uses similar language in Ephesians 4:16, describing how “the whole body, joined and held together … grows.” God is actively fitting his people together, and it is worth remembering exactly who “his people” were in Paul’s original context: Jews and Gentiles, separated for centuries by deep religious, ethnic, and social hostility. These were not natural allies. They were, in many cases, people who had every human reason to remain permanently apart.

Yet look at how the language builds across this passage: “made us both one” (v. 14); “one new man” (v. 15); “one body” (v. 16); “one Spirit” (v. 18); “one household” (v. 19); “one temple” (v. 21). The repetition is not accidental. Paul wants us to hear it. Christ did not die simply to rescue isolated individuals who then happen to occupy the same room once a week. Christ died to create a people—a single, unified structure made of very different materials.

The Construction Site

Anyone who has walked past a building site mid-project knows what it looks like: dust everywhere, noise, scaffolding, unfinished walls, materials scattered in what seems like no particular order. It is often genuinely difficult to picture what the finished building will actually look like. Nobody, however, judges a building while it is still under construction. Instead, we trust the builder.

We should display similar trust when it comes to the church, whether a single congregation or a wider fellowship of churches across different countries, cultures, and languages. The differences between us are real, and so are the tensions those differences sometimes create. But the mess of an active construction site is not evidence that the builder has abandoned the project. It is simply what construction looks like from the inside, before the scaffolding comes down.

When churches follow the builder’s design—loving one another, bearing with one another, forgiving one another, being patient with one another, partnering together for the sake of the gospel—the design gradually becomes visible, even amid the noise. This is what it means, in practice, to become a foretaste of heaven: not the absence of mess, but the presence of a builder who is patiently, deliberately shaping something whole out of very different parts.

Competition or Cooperation?

If Christ really is building one temple out of many different stones, this changes how churches ought to relate to one another. It becomes possible—necessary, even—to ask an uncomfortable question: Are we, in our rivalries and our guardedness toward other congregations, rebuilding walls that Jesus died to tear down? Christian unity can quietly become territorial. Churches can drift into competing for attention, resources, or reputation rather than cooperating for the sake of the gospel.

But where the builder is genuinely at work, something different starts to emerge: Churches become willing to cooperate rather than compete, to forgive rather than retaliate, to rejoice when another congregation is blessed rather than resent it. Stronger churches begin strengthening weaker ones. Weaker churches pray earnestly for stronger ones. Older believers invest deliberately in younger ones. None of this is competition dressed up in spiritual language. It is different stones actually allowing themselves be joined together by the builder.

This is, in its own way, a foreshadowing of eternity. Revelation 7:9 offers a glimpse of the finished structure: a multitude from every nation, tribe, people, and language gathered together before Christ. The differences do not disappear in that picture. Nations remain nations, tongues remain distinct. What disappears is the separation, the hostility, the alienation. There is unity without uniformity. That is what the temple looks like once the scaffolding finally comes down.

Trusting the Builder Now

Between now and then, there is still real work in progress, which includes real friction because of real differences that will not simply dissolve on their own. The invitation is not to pretend the construction site is tidy. It is to trust that the builder knows what he is doing, and to keep following his design rather than improvising our own.

That means choosing patience over irritation when the process feels slow, choosing cooperation over comparison when another congregation seems to be thriving, and choosing to see genuine differences—culture, language, background, personality—not as obstacles to unity but as the very materials the builder is using to construct something richer than uniformity could ever produce.

The temple is still rising. But a building is not raised for its own sake. A temple exists to be inhabited—and that is precisely where Paul takes us next: not merely a structure being assembled, but a dwelling place being prepared for God himself to live in.
