What America’s Largest & Fastest-Growing Churches Have in Common (and What They Avoid)

Each fall, Outreach Magazine publishes the Outreach 100 (outreach100.com), ranking the largest and fastest-growing churches in the U.S. (attendance is gathered via Lifeway Research’s survey plus Hartford Institute public data).   They do this every year so you should really check it out.  But we used the data, scanned the lists, and fed them through AI to reveal some very interesting patterns (outreachmagazine.com).  Here’s what you need to know…

5 Shared Practices You’ll See Again and Again

1. Multi-site + systems thinking. Most top churches operate across multiple campuses and run playbooks for weekend services, groups, volunteering, and follow-up—clear, repeatable “next steps” that scale. (Just glance at the Top-20 list: Life.Church, Church of the Highlands, CCV, North Point, Saddleback, Eagle Brook, etc.—all multi-site with robust systems.)
2. Community partnerships over going it alone. Fast-growing churches frequently meet tangible needs with local partners (schools, foster care, anti-trafficking, medical equipment lending, etc.), rather than creating parallel programs from scratch.
3. A strong volunteer culture. These churches treat serving as discipleship, build simple on-ramps, and invest in care and retention for volunteers—not just recruitment.
4. Lower the entry bar, not the discipleship bar. Leaders make it easy to belong and start engaging, while still calling people to deep formation over time.
5. Integrated next-gen focus. Young-adult and student efforts are aligned to the church’s overall mission (large-group connection points + small groups + lots of serving opportunities), not siloed ministries running on separate tracks.   This means making sure young people participate in, belong to, and shape church-wide rhythms (worship services, serving, outreach), not just separate events.  It also means creating pathways where kids, then students, then young adults can move seamlessly and see themselves as integral to the church’s mission (not just “when you’re older you’ll join in”).

What They Tend to Avoid

• Program sprawl. Instead of adding endless ministries, they prioritize a few high-impact pathways (weekend → groups → serve/mission) and partner externally for community needs.
• Siloed age ministries. Several leaders explicitly moved away from isolated young-adult “churches within a church,” shifting to rhythms that funnel people into groups, serving, and campus life.
• Bait-and-switch discipleship. They resist watering down content; instead, they talk about “the hard stuff” plainly and pastorally, which increases trust with Gen Z/young adults.
• Volunteer churn by neglect. High performers don’t assume volunteers “just show up”—they teach a theology of serving, match gifts to roles, and keep care systems strong.

Youth & Young-Adult Ministry: What’s Working

• Belong → Believe → Become runway. Churches are giving a longer “runway” to connection (hangouts, monthly YA gatherings, then small groups, then weekly rhythm), while keeping the discipleship bar high.
• Speak to real questions. Teaching tackles the topics students already carry from their feeds (identity, sexuality, doubt, hell, race, etc.). Honest, Bible-anchored conversations build credibility.  They avoid “Bible stories” and share “Bible accounts” with modern connection points.
• Serve early and often. Young people are plugged into tangible service (local partnerships, mission engagement) as a primary discipleship lever, not an add-on.
• Consistency beats hype. Weekly or monthly anchor gatherings plus small groups are the backbone; outcomes are measured in long-term faithfulness more than one-off spikes.

If You’re Leading Students or Young Adults, Try This

1. Name your pathway. Publish a two-step on-ramp for students: “Gather → Group → Serve.” Then measure how many make each jump.
2. Adopt two local partners. Pick one school and one compassion partner; serve them for two years with students and parents side-by-side.
3. Teach the hard things well. Plan several week-long series addressing the “spicy” topics your teens already see online, framed by grace and Scripture.  Don’t avoid the hard topics just because they are controversial.  They see it all the time, but many don’t know how to respond.
4. Disciple through serving. Treat student volunteer roles (kids ministry helpers, tech, hospitality, local outreach) as formation, not just “help.” Build coaching into every role. Don’t put your high school students in a Sunday school class; get them serving on Sunday mornings or join an adult class.

• The Outreach 100 “Largest Churches” ranks by average weekend attendance (not membership); data blends Lifeway’s survey with publicly available figures validated with the Hartford Institute. This helps explain year-to-year shifts and the prominence of multi-site, often nondenominational or Baptist churches at the top.
• Articles tied to the Outreach 100 consistently highlight partnerships, volunteer cultures, and intentional discipleship pathways as common growth factors, especially for ministries to young adults.
