There is a moment in Paul's letter to the Ephesians that stops you cold if you let it. He is writing to a community of people who have done something remarkable, something that the world around them would have considered nearly impossible. Jewish believers and Gentile believers, two groups separated by centuries of cultural, religious, and ethnic division, are sitting in the same room together, trying to build something new. And Paul wants to make sure they never forget what it took to get there.

"Remember," he says. Remember where you came from. Remember what you were without.

It is a strange way to begin an encouragement, and yet it is exactly the right one.

The Walls We Build

Ephesus in the first century was a cosmopolitan Roman city, wealthy and culturally diverse, home to one of the seven wonders of the ancient world. It was also home to a Jewish community that had maintained its distinct identity within that broader Roman culture. When followers of Jesus began gathering there, they brought those distinctions with them into the room.

Paul addresses this directly in Ephesians 2:11-12, calling his readers to remember the labels that once defined them. The Gentiles had been called "the uncircumcision" by those who considered themselves insiders to God's covenant. It was not a flattering term. It was a way of saying: you do not belong here. You are outside the boundary. You are not one of us.

But Paul makes a pointed observation. He notes that this distinction was made by a circumcision "made in the flesh by human hands." In other words, this wall was not God's idea. It was ours.

That is worth sitting with for a moment. So many of the divisions we treat as natural, as inevitable, as simply the way things are, were constructed by human beings. We built them. We maintain them. We pass them down. And we have done it for so long that we sometimes forget they were ever built at all.

We are remarkably skilled at this kind of construction. The categories multiply: us and them, insider and outsider, left and right, religious and secular. And the Church, the very community that should be leading the world toward reconciliation, has not been immune. One theological seminary estimated in 2019 that there are nearly 45,000 distinct Christian denominations in the world. The people most called to model unity have found extraordinary ways to fracture it.

Something Entirely New

And yet, here is where the passage turns. Ephesians 2:13 pivots with two of the most important words in Scripture: "But now."

But now, in Christ Jesus, those who were far off have been brought near. Not through their own effort. Not through determination or moral achievement. They were brought near. The distance was closed not by human striving but by divine action.

What Christ accomplishes, according to Paul in verses 14 through 16, is not merely a ceasefire between two opposing groups. It is not a diplomatic agreement where two parties agree to tolerate one another while privately maintaining their contempt. Paul describes something far more radical. He calls it the creation of "one new humanity in place of the two."

One early church father compared this to alchemy, the ancient belief that two base materials could be combined to produce something entirely different and more valuable. The image is apt. Christ does not simply change one group into the other. He does not ask the Gentiles to become Jewish or the Jewish believers to abandon their heritage. What emerges is something new altogether, a community that could not have existed without the reconciling work of the cross.

This is what Paul means when he says, "He is our peace." Not that Christ produces peace as a byproduct of his work, but that peace is bound up in who he is. And the peace he is talking about is not merely the absence of open conflict. It is the Hebrew concept of shalom: wholeness, completeness, everything as it was meant to be.

The Civil War ended in 1865. The pitched battles stopped. But anyone who looks honestly at the history that followed knows that the cessation of violence did not produce shalom. Two people who manage to avoid each other, or who perform civility when they must share a space, are not experiencing wholeness. They are simply managing the distance between them.

The Work of Peacemaking

So what does it look like to actually pursue this kind of peace? Three qualities mark the person who takes this work seriously.

First, peacemakers believe the best of others. Every person, regardless of how different they are from us, regardless of what we disagree about, has been made in the image of God. That does not stop being true because of our disagreements, even fundamental ones. If we cannot start from that foundation, we will never get anywhere.

Second, peacemakers lead with humility and empathy. Curiosity is an underrated virtue. Rather than assuming we have all the answers and waiting for others to come around, peacemakers ask questions. They listen closely. They try to understand before they try to be understood. Jesus modeled this throughout his ministry, asking questions not because he lacked answers but because he was more interested in drawing people toward clarity than in winning arguments.

Third, peacemakers hold truth and grace together. Peacemaking is not the same as conflict avoidance. It does not mean suppressing honest disagreement or pretending everything is fine when it is not. Jesus had real disagreements with people and did not back away from them. But truth, in his hands, was always accompanied by grace. Grace without truth becomes permissiveness. Truth without grace becomes cruelty. Neither one alone is sufficient.

Start Here

Here is the most important thing: this does not begin with geopolitical negotiations or institutional reform or sweeping cultural change. It begins with you.

Think of one wall in your own life. One relationship that has quietly calcified. One person you have written off or learned to avoid. One assumption that has kept someone at a comfortable distance.

You do not need a complete solution this week. Just one step. One brick removed.

That is how it happens. That is how it has always happened. The conditions for the peace we long to see in the world already exist. We do not have to create them. We simply have to be willing to live them out, one small act of courage at a time.

Let there be peace on earth, and let it begin with me.
