The Thermostat
There is a difference between a thermometer and a thermostat that most of us never give a second thought.
A
thermometer tells you the temperature of the room. It reads what is already there, adjusts to whatever surrounds it, and reports back faithfully. It is reactive by design; in other words, it waits to be acted upon. The room decides what the thermometer says.
A
thermostat does something different entirely. It doesn't adjust to the room; rather, it sets the temperature. It decides what the room will become and then works quietly, persistently, without fanfare, until the room catches up. It doesn't wait for conditions to improve before it does its job. A thermostat makes the first move.
Jesus had a word for the thermostat kind of person. He called them
peacemakers. And He said they would be called
children of God. Now here is something worth pausing on, because the promise attached to this beatitude is unlike any of the others.
The other beatitudes talk about the kingdom of heaven, seeing God, or receiving mercy. But this one claims they will be called children of God. And that was not some throwaway compliment. It meant something in the first century, and it means something today.
I was watching one of my boys play baseball one evening, standing along the third base line with a buddy of mine. Out of nowhere, he looked over at me and grinned. "You can't deny those kids", he said. "Every time I see them I see you."
That is what Jesus is describing. A family resemblance so clear that nobody has to be told. Which means that if peacemakers are the ones who look like their Father — then the central characteristic of God must be peacemaking itself. The whole sweep of Scripture points exactly there. A God who keeps moving toward people who keep turning away. A God who initiates, absorbs, returns, and offers again. A God who, even when the door keeps closing, finds another way to knock.
That is the family business. And Jesus is inviting us into it.
But we need to be careful about what we think peace means. When most of us hear peace, we think about what is absent. The absence of conflict or the absence of noise. The quiet that settles in when everyone has finally stopped fighting.
But that is not what Jesus meant. The word He used for
peacemaker doesn't appear anywhere else in all of Scripture — it is unique to this one beatitude — and at its root is the Hebrew understanding of
shalom.
And
shalom is not about absence.
Shalom is about presence.
Shalom is the presence of wholeness and the presence of grace. It is about a restoration to the way it should always meant to be. Shalom is taking what was broken and making it whole. We could translate this beatitude, “Blessed are the whole-makers" - the one who moves toward broken things and offers restoration. Now those who are “whole-makers” or “peacemakers” are not naive about how broken things are. They have simply decided that the broken thing is worth moving towards. They are not passive; they are like a thermostat, setting the temperature. Peacemakers make the first move.
I know something about what that costs.
My father left when I was young. He left without a goodbye, a note, or a warning. He was just gone, the way a foul ball disappears into the stands and doesn't come back. For a long time I didn't think much about it. You can't grieve what you don't yet understand.
But years later things changed for me as I was leading a group through Philip Yancey's book
What's So Amazing About Grace? One of the chapters was titled
"Breaking the Chain of
Ungrace,"
in which Yancey discusses what it takes to break the cycles of resentment, blame, and pain. Something in it reached into my chest and wouldn't let go, so I made a decision. I was going to be a thermostat and move toward the broken thing.
I found him on the internet along with his office number. His secretary answered and told me I must have the wrong number — Mr. Vershel didn't have any children. But I didn’t quit. I sent an email carefully written, making sure that there was no blame or judgment - - just a son wanting to know his dad. And I waited and waited and…then I sent it again. And again nothing.
Years later I found him on Facebook. So of course I sent a message and a friend request. And again silence. Three attempts and three doors closed. Three times the same basic message: you do not exist.
“Blessed are the peacemakers”, Jesus says. He does not say, "Blessed are the peacemakers whose peace is accepted."
I don't know exactly how to say what happened next without it sounding like something it isn't. There was no reconciliation. No phone call where everything finally got said. No moment where the distance collapsed, and we found each other on the other side of it. He died.
And somehow — I still don't fully understand the path it traveled — his ashes ended up with me.
There is a box in my closet that holds what is left of him. Right next to the box with his old baseball glove — a left-handed glove I found years later, a glove that never fit me, from a game we never played together. One box for the man who left. One box for the life we never had.
I did not plan to become his keeper. But here we are.
And I have thought about this more than I can explain — the man who denied having children ended up in the closet of one of the children he had. The peacemaker became the keeper of the one who would not make peace.
I don't think that is an accident. I think that is shalom working in ways I cannot fully trace.
Because shalom doesn't always look like resolution. Sometimes it looks like faithfulness in the face of rejection. Sometimes it looks like a thermostat that keeps working even when the room never warms up. Sometimes it looks like a son who keeps his father's ashes because there was nobody else to keep them — and found, in that strange and quiet act, something that felt less like loss and more like grace.
The
Unlikely Altar
for this beatitude is not the moment peace is finally achieved. It is the moment it is offered anyway. It is the phone call you make and the email you send into the silence. It is the move you make toward the broken thing — not because you are certain it will work, but because you are a chip off the old block of a God who never stopped moving toward you.
Maybe that relationship in your life never gets resolved the way you hoped. Maybe the door stays closed. Blessed are the peacemakers still. Not because the peace was accepted. But because they looked like their Father when they offered it.
May we know, may we remember, may we never forget — we come from a God who is in the business of moving toward broken things. That is the family resemblance. That is what people are supposed to see when they look at us.
Be the thermostat.
