For years, leaders have shared with me about their desire for Sunday School to grow. They discussed attendance goals, outreach strategies, curriculum options, and classroom space.
All of those things matter. But I’ve become convinced that one factor influences long-term Sunday School growth more than almost anything else:
Churches that consistently start new classes consistently reach new people.
Churches that don’t start new groups eventually hit a growth ceiling. That’s why every church that wants a healthy future needs to answer a simple question: Are we creating enough new opportunities for people to connect and grow?
New Classes Create New Opportunities
Most Sunday School classes begin with a sense of excitement and mission. People invite friends. Relationships form. There is room for newcomers to find their place.
Over time, however, something naturally happens. The class becomes a close-knit family. Don’t misunderstand me. That’s a good thing. Christian community should produce deep relationships. But the same relationships that make a class healthy can also make it difficult for newcomers to connect.
A visitor walking into a room where everyone already knows everyone else often feels like an outsider, even when people are friendly. The problem isn’t hostility. The problem is familiarity. New classes solve that problem because everyone is building relationships at the same time.
Empty Chairs Don’t Mean Open Doors
One of the biggest misconceptions in Sunday School is believing that empty seats automatically mean a class has room to grow. Not necessarily. A class may have ten empty chairs and still be socially full.
Members know where they sit. They know each other’s stories. They have established traditions and routines. A newcomer may be welcomed warmly but still struggle to find a place in the group.
New classes offer something established classes often cannot offer: a fresh start. People aren’t joining someone else’s group. They’re helping create the group.
New Classes Reach New People
Churches say they wants to reach new people. The question is whether we’re creating environments where new people can connect.
I’ve seen churches spend thousands of dollars on outreach events only to struggle with assimilation because there was nowhere obvious for newcomers to connect and belong.
Evangelism and discipleship are connected (think Great Commission: baptizing and teaching them to obey). If we’re serious about reaching people, we must be equally serious about providing places where those people can grow. New classes become front doors for new members.
New Classes Develop New Leaders
Perhaps the greatest benefit of starting new classes has nothing to do with attendance. It has everything to do with leadership. Every new class creates opportunities for teachers, apprentices, greeters, member care leaders, friend care leaders, and more.
Churches don’t discover leaders by accident. They discover leaders by creating opportunities for people to serve. A Sunday School ministry that never starts new classes eventually runs out of places for leaders to develop.
The Future Depends on New Launches
Healthy things grow. Growing things make room. Making room requires launching new classes/groups and new leaders.
If twenty new people showed up at your church this Sunday, where would they go? Who would disciple them? What class would welcome them? What leader would shepherd them?
Those questions matter. Because church growth isn’t really about numbers. It’s about people. And people need places to connect and belong.
Call to Action
This week, take an honest look at your Sunday School ministry. Ask these three questions:
- When was the last time we started a new class?
- Who are we currently trying to reach?
- Where would a first-time guest naturally belong?
If those questions make you uncomfortable, that’s okay. Revolutionary ministries are built by leaders who are willing to confront reality and create change.
The future of your Sunday School may not depend on growing existing classes. It will most likely depend on starting new ones. Will you start one soon? Be revolutionary!
