Tim started volunteering at The Garage when he was twelve. His handprint is literally in the concrete under our first lift. There was no ceremony; he was just a kid who was there when something was being built, and kids leave marks on things. He’s eighteen now. Over those six years he found mentors he never would have found in a Sunday school class, and he learned skills, and he developed his own way of leading: dry humor, honest questions, a devotion format he picked up by watching the adults around him. He’s heading to college to study engineering, carrying a picture of bi-vocational ministry he saw modeled by pastors who showed up at the garage in their work clothes. Nobody ever enrolled Tim in a program. That’s discipleship through serving, and I’ve come to believe it’s one of the most powerful kinds there is.
Outreach is something God does for the church
We usually think of outreach as something the church does for the community, and it is. But Tim’s story, and a lot of others, taught me that outreach is also something God does for the church.
No curriculum formed Tim. Taking part in real work did, alongside real people who loved God and loved him.
Jesus didn’t run a classroom
None of this is new. It’s the pattern of discipleship you see all through the Bible.
Jesus invited people to follow him into the work. He took his disciples to places where the needs were real and asked them to help meet those needs. He debriefed with them afterward. He sent them out and let them fail and welcomed them back. Instruction mattered, but he formed them through the friction of actual ministry.
James puts it bluntly: “But be doers of the word, and not hearers only, deceiving yourselves” (James 1:22). He’s not saying hearing is bad. Hearing without doing produces a kind of self-deception, where you get the feeling of formation without the substance. An outreach ministry, at its best, is the doing that makes the hearing real.
Teaching still matters. Sunday preaching and Bible study are the homestead where people are rooted. But how many of us have sat through years of good teaching that never got tested? Service tests it.
The hard moments are the lessons
Some of the most formative things I’ve witnessed at The Garage weren’t planned. Chuck, serving faithfully while carrying pain from home. Kevin, staying four extra days to finish a job because he said he would. Bryan, laughing when everything went sideways.
That’s more than impressive volunteer behavior. That’s the real curriculum of character formation. You can talk about faithfulness and patience and keeping your word and grace under pressure in a classroom, but they get built when a job goes wrong on a cold night and you stay anyway.
So I tell church leaders what I wrote in Turn the Key: don’t add a discipleship program to your outreach ministry. Build discipleship into the DNA of the outreach itself. Let the work be the curriculum. Let the community of volunteers be the small group. Let the hard moments be the formation.
How to build formation into the work
“Let it happen naturally” isn’t the same as “leave it to chance.” So here are a few ways to be intentional without turning your ministry into a class.
Start with a short devotion. At The Garage, every work session begins with a brief moment before the work starts, where a volunteer shares a story, a scripture, and a question. It takes five minutes, and it frames the evening and gives volunteers, including young ones like Tim, a chance to lead.
Work side by side, across generations. The conversations that matter most happen with your hands busy on a job that matters. Pair an experienced volunteer with a newer one on purpose, or put a teenager next to a retiree. The talk that happens under a hood, or over a sink of dishes, or in a garden row, goes places a classroom discussion rarely does.
Debrief the hard nights. Jesus debriefed with his disciples. When a session goes badly, when a customer is angry, when someone you’ve helped for months disappears, don’t just clean up and go home. Take ten minutes first. Ask what happened, what people felt, and where they saw God, or didn’t. That’s how hard experiences turn into formation instead of burnout.
Let people be known. Accountability grows when you serve alongside the same people week after week. People who are known by their fellow volunteers tend to show up, keep their word, and grow.
Give responsibility early. Tim started as a helper, handing people tools and learning the culture, and over time he was trusted with more: leading devotions, recruiting new volunteers. Don’t wait until someone is “mature enough” to give them something real to carry. Responsibility is part of how they mature.
A question worth asking your team
The discussion questions at the back of the book include this one: If a first-time volunteer joined your outreach ministry today, what would they be learning about faith six months from now?
Be honest with yourself on that one. If the answer is “how to run the sign-in table,” your ministry may be serving the community well while missing what God wants to do for your church through it. If the answer is “how to be faithful when it’s hard, how to love people who don’t thank you, how to talk honestly about why they serve,” then the work is already becoming the curriculum.
Then pick one thing to try this month. You could add a five-minute devotion before your next service project. Or ask one experienced volunteer to take a new one under their wing. Or schedule a short debrief after your next hard session.
The people you’re forming
Twenty years from now, the people your church served will matter, and so will the people who did the serving. Some of your most faithful future leaders are teenagers handing someone a wrench right now, watching how the adults around them handle a bad night.
So let them watch, and let them help, and let the work form them.
