(Introduction – 2 minutes)

Grace, mercy, and peace be to you from God our Father and from our Lord and Savior, Jesus Christ. Amen.

My dear friends in Christ,

On this first Sunday after Trinity, the church calendar turns from the great works of God the Father, Son, and Holy Spirit to the life of the people who follow Him. And the first thing the Spirit wants to show us is a picture of how we live together.

Luke paints a beautiful, almost impossible portrait in Acts 4: “All the believers were one in heart and mind. No one claimed that any of their possessions was their own, but they shared everything they had.”

But if we are honest, reading this passage today feels less like an inspiring goal and more like looking at an old photograph of a family we never knew. Because for many of us, the congregation is shrinking. The pews are less full. And outside these doors, the assumption is no longer, “I need the church,” but, “Why would I need the church? I have YouTube. I have hiking on Sunday. I have my own spirituality.”

How do we keep unity when the world doesn’t want what we’re selling? How do we maintain this “one heart and mind” when we are anxious about numbers, budgets, and survival?

Let us look at three anchors from our text.

Part 1: The Problem – We are not “needing” each other (3 minutes)

First, we must name the elephant in the sanctuary. The world outside says, “I don’t need the church.” But if we are honest, the world’s attitude has infected the inside. Many believers today think, “I love Jesus, but I don’t necessarily need the congregation.”

Why? Because we have privatized faith. In the West, faith has become a consumer product. We choose a church like we choose a streaming service—based on what we get out of it. Music? Good. Pastor? Funny. Childcare? Excellent. When the “service” fails, we leave.

But look at Acts 4. These believers didn’t come together because it was efficient or entertaining. They came together because they had just been threatened by the same authorities who killed Jesus. They prayed, and the place was shaken. The unity in verse 32 is not a feel-good fellowship; it is a survival fellowship. “None of them said that anything he had was his own.”

Why? Because when you truly believe that the same Spirit who raised Christ from the dead lives in you and in the person next to you, you cannot say, “I don’t need you.” The world is dying of loneliness in a hyper-connected age. And the church has forgotten that we are not a voluntary association. We are a body. A hand cannot say to a foot, “I don’t need you.”

So the first step to unity in a shrinking church is repentance: turning from the lie that I can be a Christian alone. You cannot.

Part 2: The Power – “Great Power” & “Great Grace” (3 minutes)

Now notice the two results of their unity. Verse 33: “With great power the apostles continued to testify to the resurrection… and much grace was upon them all.”

Here is the counter-intuitive truth for shrinking congregations: Unity does not grow the church; the Spirit grows the church through unity. But disunity kills the witness.

When we bicker over carpet color, when we gossip over coffee hour, when we split because of a minor theological hobby horse, we are telling the world: “Our God is weak. Our resurrection is a myth.”

But when a congregation—even a small one—lives with open hands, what happens? Great power and great grace. Why? Because the resurrection is not just a past event. It is a present reality. When you give away your money, your time, or your pride for the sake of another, you are acting like a resurrected person. You are proving that death does not have the final word.

The world does not need a bigger church. There are plenty of big arenas with light shows. The world needs a different kind of community—one where people are not competitors but co-heirs.

Look at Barnabas in verse 36. They call him “Son of Encouragement.” He sold a field and laid the money at the apostles’ feet. He didn’t post it on social media. He didn’t start a foundation. He simply said, “What I have is for us.” That kind of radical sharing is the most attractive apologetic in a lonely, greedy world.

Part 3: The Strategy – Small, Holy, and Generous (3 minutes)

So how do we actually do this on the 1st Sunday after Trinity, in a congregation that is smaller than last year?

You stop trying to be big. You start trying to be faithful.

The early church did not have a marketing plan. They did not have a growth strategy. They had a life strategy: “There were no needy persons among them” (v. 34).

Notice: The goal was not to have a full building. The goal was that no brother or sister was hungry, naked, or alone.

Here is the key for us today. The reason people do not “need” the church is because we have not shown them what the church actually is. If the church is just a lecture hall with hymns, of course Netflix wins. But if the church is a family where a single mother finds a mechanic to fix her car, where an elderly widow finds a teenager to shovel her walk, where a unemployed man finds a community that pays his rent for one month—the world cannot replicate that. The world can replicate entertainment. It cannot replicate agape love.

You keep unity in a shrinking reality by shrinking the definition of “neighbor” to the person in the next pew. You start with radical hospitality not as a program, but as a heartbeat.

Barnabas didn’t save the whole Roman Empire with his field. He saved a few people from hunger. That was enough. For the Spirit, “enough” always multiplies.

(Conclusion & Application – 1 minute)

Therefore, beloved, do not be afraid of being small.

Do not be discouraged that the crowds are gone. The first believers were often a hundred here, fifty there. But they were “one in heart and mind.” And because they were one, “great grace” was upon them all.

So this week:

1. Look at your possessions. Is there anything you are holding so tightly that it is strangling your unity?
2. Look at your grudges. Is there a fellow member you have written off? Be a Barnabas. Be a son or daughter of encouragement.
3. Look at the world. It is starving for exactly what you have: a community that shares, forgives, and stays.

Let us pray: Lord Jesus, you prayed that we would be one as you and the Father are one. Forgive our lonely individualism. Fill our small congregation with great grace. Make us so generous that our shrinking walls become a furnace of resurrection love. For we ask this in the name that unites all things, even Jesus Christ our Lord. Amen.
