Young adults are returning to church and they’re coming for the community, not just the theology. Small groups pastors might be sitting on the key to America’s quiet revival.
Something unexpected is happening in churches across America. After decades of dire predictions about Christianity’s inevitable decline, the trend lines are bending. Not dramatically. Not everywhere.

Not everywhere. But quietly and surely.

Millennials who stopped attending church years ago are trickling back. Gen Z twenty-somethings, the generation once written off as hopelessly secular are showing up on Sunday mornings at rates that haven’t been seen in Barna Group’s tracking data since these cohorts emerged. And critically, they’re not just showing up once out of curiosity. They’re staying.
The numbers tell a remarkable story: 66% of U.S. adults now report having made a personal commitment to Jesus that remains important to them, a 12-percentage-point jump since 2021, representing roughly 30 million more Americans following Jesus. Among Millennials specifically, weekly church attendance nearly doubled from 21% in 2019 to 39% in 2023. Gen Z and Millennial churchgoers now attend an average of 1.8-1.9 weekends per month, actually exceeding older generations for the first time in modern church history.
David Kinnaman, CEO of Barna Group, calls it “the clearest trend we’ve seen in more than a decade pointing to spiritual renewal and it’s the first time Barna has recorded such spiritual interest being led by younger generations.”
But here’s what makes this moment so crucial for small groups pastors: These young people aren’t coming back for the preaching. They’re coming back for each other.
The belonging boom
When researchers asked what actually draws people to church, the results were stunning. Among all churchgoers except Evangelicals, a sense of community and belonging actually outranked shared spiritual beliefs as the primary motivation, 55% cited community versus 53% who cited shared faith. For Mainline Protestants, that gap widened further: 63% came primarily for community.
In most churches, belonging now beats believing.
This isn’t about watering down theology or compromising doctrine. Koinonia must be community centered in the Gospel. Rather it is a shift in the first step from being rational to relational. It’s about recognizing a fundamental shift in how people come to faith in 2025. The old model assumed belief preceded belonging: come to church, learn the gospel, join the community. The new reality flips that sequence: belong to community, explore faith together, deepen belief.
And today’s church has nothing else that facilitates that journey quite like small groups.
Consider the data on personal invitation. Thirty-one percent of non-churchgoers say they would attend church if invited by friends or family, rising to 34% among 18-34-year-olds. When it comes to engaging Scripture, 22% of non-churchgoing young adults say they’d read the Bible if recommended by a trusted family member or friend compared to just 13% who’d respond to a celebrity endorsement.
The math is simple: relationships are the new front door to faith.
The loneliness crisis meets the church opportunity
To understand why community has become so magnetic, you have to understand what young adults have been through. Research found that 61% of 18-25-year-olds reported “miserable degrees of loneliness” coming out of the pandemic. Social media promised connection but delivered isolation. Remote work blurred the boundaries between professional and personal life. Even as restrictions lifted, the infrastructure of casual socializing third places where people naturally gathered had crumbled.
“Twice the number of U.S. adults tell us they are lonely compared to 10 years ago,” notes David Kinnaman. “That relational gap represents a real opportunity for churches.”
Small groups are uniquely positioned to fill that gap. Unlike Sunday services, small groups offer the consistent, face-to-face interaction that rebuilds the social fabric. Unlike social media connections, small groups provide depth, vulnerability, and the accountability that comes from regular in-person gathering. Unlike therapy (which young adults are also seeking in record numbers), small groups offer transcendent purpose alongside emotional support.
Churches seeing the most dramatic growth post-pandemic share a common thread: they’ve created intentional spaces for genuine relationship. They’re hosting small groups aligned with young people’s actual interests. They’re creating safe environments for real conversations about mental health, climate anxiety, justice, and doubt. They’re meeting people where they already are, sometimes literally, using social media platforms and coffee shops rather than insisting everyone come to the church building first.
What the UK revival reveals
The clearest picture of what’s possible comes from across the Atlantic. In England and Wales, monthly church attendance rose 50% over six years, with 18-24-year-olds quadrupling from 4% to 16% attendance. Young men, the demographic most churches had given up on, increased from 4% to 21%, making them the largest cohort of regular churchgoers.
When researchers asked why, the pattern was clear: young people gravitated toward churches offering both theological substance and authentic community. They weren’t looking for entertainment or marketing gimmicks. They wanted spaces where they could wrestle with real questions, experience genuine acceptance, and connect with people who took faith seriously.
Intergenerational mentorship emerged as particularly powerful. Young people explicitly wanted older Christians willing to share life, faith, and wisdom through relationship rather than lecture. One researcher described it as the “Philip and the Ethiopian eunuch model”, running alongside someone’s journey, explaining scripture as they ask questions, rather than broadcasting from a stage.
Does that sound like what happens in a healthy small group? It should.
The practical path forward
So what does this mean for small groups ministry in your church? Here are five concrete next steps:
1. Reframe your small groups as evangelistic, not just discipleship tools. For decades, churches have treated small groups primarily as places to deepen the faith of existing believers. That’s still valuable, but the data suggests small groups should also be your primary entry point for unchurched seekers. When someone visits on Sunday, the invitation shouldn’t just be “come back next week” it should be “want to grab dinner with our Tuesday night group?” But rather than make this an additional obligation for your leaders, show them that it is an opportunity for a lighter load. Rather than “me” individually evangelizing my friends, coworkers, and youth sports acquaintances, now “we” as a group can invite someone in. It flips the equation from one person trying to change a community to a community inviting one person in.
2. Build invitation into the DNA of every group. Sixty percent of Protestant church members invited at least one person to church in the past six months, according to Lifeway Research. But invitation to small groups may be even more effective, because the barrier to entry is lower and the relational connection is clearer. Train your group leaders to always have open chairs. Make it normal for groups to regularly discuss “who could we invite?” not as a program but as a posture. Even closed groups can be open to this because the person being invited already has an existing relationship with one other person in the group, and often at least two.
3. Create affinity-based groups that match where young adults actually are. Generic “20s and 30s groups” are fine, but consider groups organized around shared interests, life stages, or questions: a group for parents of young kids wrestling with how to raise them with faith; a group for people working in tech discussing AI ethics from a Christian perspective; a group for those exploring Christianity with zero church background. The American Bible Society found 69% of non-churchgoing Gen Z members want communities providing opportunities to help others so why not small groups organized around serving together? Personally, I think there are many issues with affinity groups, however as people are trending towards meeting in coffee shops and on site at the church, you have the opportunity of reframing these specialized affinity groups as “semester long, ted talks.” This is a far more attractive opportunity to bring in spiritually curious people as well as engage your existing members.
4. Embrace vulnerability and real questions. Gen Z is searching for “presence, not platitudes,” as one observer put it. They’re coming to faith “through burnout, through longing,” asking whether anyone out there cares about their actual struggles. Small groups that allow space for doubt, mental health conversations, and messy questions will win the trust of a generation burned by superficiality. Your group leaders need permission, even encouragement, to say “I don’t know” and “I struggle with that too.”
5. Measure belonging, not just attendance. Start tracking not just how many people come to your groups, but how many would say they have a close friend in the group. Gallup found that people with a best friend in the congregation had dramatically better attendance and felt more cared for. Friendship, it turns out, is the most effective form of evangelism, far more than door-knocking or formal programs. The goal isn’t full small groups; it’s groups where genuine friendships form.
Casting the vision: Your town’s quiet revival
Here’s the thing about revivals: they don’t usually start with stadium events or celebrity preachers. They start in living rooms. In coffee shops. Around dinner tables. They start when a handful of people gather regularly, open their lives to each other, and discover that the presence of God shows up in authentic community.
The “quiet revival” happening in the UK didn’t make headlines for years. It was built one small group at a time, one invitation at a time, one unlikely friendship at a time. Young people discovered Jesus through relationships first, then showed up at church, then brought their families.
Your town could be next.
Imagine six months from now: your small groups have embraced a posture of radical hospitality. Every group has invited new people. Some groups have multiplied because they grew too large. Young adults who haven’t been to church in years are gathering in someone’s apartment on Thursday nights, wrestling with Scripture, sharing their anxieties about the future, and slowly discovering that the Jesus they dismissed might actually speak to their deepest longings.
Imagine a year from now: those young adults are inviting their friends. Your Sunday attendance is up, but more importantly, your small group attendance has exploded. The church lobby buzzes with the energy of people who genuinely want to be there, because they’ve found something our lonely, fractured culture can’t offer a community that sees them, knows them, and loves them anyway.
Imagine five years from now: the young adults who started coming for friendship have become small group leaders themselves. They’re mentoring the next wave of seekers. Your church has become known in town as the place where lonely people find family, where questions are welcome, and where spiritual transformation happens not through programs but through relationships. The local college students talk about your groups the way they talk about their favorite bands. Parents who’d written off church consider trying again because their twenty-something kids keep raving about their Tuesday night gathering.
That’s not fantasy. That’s what’s already happening in pockets across America and dramatically across Europe. The research is clear: young adults are hungry for authentic community and transcendent purpose. They’re lonelier than ever and more spiritually curious than we assumed. They’ll show up if invited by someone they trust. They’ll stay if they experience genuine belonging. And they’ll bring others once they’ve found something real.
The quiet revival may not make headlines. It probably won’t go viral on social media. But it will transform lives, families, and entire communities, one small group at a time.
The question isn’t whether young adults are seeking. The data shows they are. The question is whether your church’s small groups are ready to welcome them.
What to do Monday morning
Here’s your immediate action plan:
- This week: Send an email to your small group leaders sharing these trends. Ask them: “If our groups became the primary way unchurched people discovered Jesus in our community, what would need to change?”
- This month: Gather your leadership team and honestly assess: Are your groups optimized for existing believers or for seekers? Do your leaders know how to welcome someone with zero church background? What’s your strategy for helping friendships actually form (not just hoping they happen)?
- This quarter: Launch one pilot “seeker-friendly” small group. Make it explicitly for people exploring faith. Promote it not as “Bible study” but as “conversations about meaning, purpose, and the big questions.” Staff it with your most relationally gifted, theologically grounded, naturally hospitable leader. See what happens. If you’re looking for a place to start, try Alpha.
The decline of American Christianity isn’t inevitable. The data suggests the tide may already be turning. But revivals don’t happen automatically, they happen when God’s people create space for the Spirit to move.
Your small groups ministry might be exactly that space.
