Steward Growth to Sustain Long-Term Health

In 8th grade, I thought I was unstoppable. A growth spurt gave me height, leverage, and what felt like destiny. I could clear high jump bars with a scissors kick while others struggled. No training, no technique, just raw advantage.

I beat everyone in my school, made it to my town’s track and field meet, and placed well. I was on top of the high jump world. (Albeit it was a very small world!)

In my freshman year of high school, I was toast. Everyone else had learned the Fosbury Flop…the backward roll that revolutionized high jumping. My height advantage evaporated. Suddenly, I couldn’t clear the same bars, and I didn’t even make the varsity team.

Lesson learned: Growth can make you lazy. It can trick you into thinking you’re great when you’re just tall.

Churches fall into the same trap. Growth feels like validation: more people, more buzz, more money. However, growth can be toxic if it masks underlying weaknesses. It’s a sugar high that makes leaders feel invincible when, in reality, they’re just riding momentum.

The hard truth: the very growth you’re celebrating may be setting you up for decline.

Let’s break it down. Five areas where unchecked growth quietly kills future growth:

1. First-Time Guest Capture Rate
2. New Donor Retention Gap
3. Follow-Up Speed to First Touch
4. Kids/Students Capacity Ratio
5. Staffing Leverage

1. First-Time Guest Capture Rate: Growth Without Names = Decline in Disguise

If you don’t know who your guests are, they don’t exist. Churches celebrate attendance spikes but often fail at the most basic task: capturing guest info.

Here’s the brutal math: in many churches, only 3 out of 10 first-time guests fill out a connect card or text-in form. That means, 70% leave without a trace. Imagine running a restaurant that never records who dines there. That’s not strategy…it’s negligence. [ref]

Unchecked growth hides failure. When 100 people show up, you don’t feel the loss of the 70 who disappear. But fast-forward six months: you’ll plateau, scratching your head about why your “record Sundays” aren’t leading to real growth.

If your church is growing, you should see new visitors each week—roughly 2% of your average attendance. If your attendance is 1,000, that means week in and week out, you are averaging 20 guests that you could contact, follow up with, and invite to be a part of your community. If you don’t see this regularly, you are missing guests.

Without this new guest information, you are just gathering a crowd that you won’t be able to move towards deeper community and connection. Your growth will plateau and slide into decline. You will be left wondering where all the people went.

• Audit your capture rate for the last three months. Not an estimate, an actual number.
• Set a benchmark goal: at least 2% of every single week should be first-time guests that you can contact.
• Create frictionless ways to respond: text-in, QR codes, digital follow-up.
• Use an “ethical bribe” …a gift that makes people want to give you their info.
• Assign accountability: one staff member or volunteer owns the process every week.

Catch their contact information. No contact information, no long-term growth.

2. New Donor Retention Gap: The Revolving Door of Giving

Every pastor gets excited about first-time givers, but most of those givers will never give again. In the nonprofit world, donor retention hovers around 20%. This means, 8 out of 10 first-time donors vanish. [ref] For churches, the numbers aren’t much better.

Do you know your church’s donor retention rate? But even more pointedly, do you know the retention rate of new donors to your church? If the gap between these continues to grow, your church will run out of money, and your growth will stumble. Many churches have a core of faithful, long-term donors (that’s why the church around the corner from your place, with just a few people left, hasn’t died), but it takes more intentional effort to onboard new donors to fuel the future of the mission.

Growth masks this churn because new people continually replenish the bucket. But it’s a leaky bucket. Giving totals may rise, but the base is fragile. When momentum slows…or the economy dips…you’ll discover you’ve been funding ministry with one-night stands, not long-term partners.

• Track your first-to-second gift rate. If 100 people give for the first time this year, how many give again within 90 days?
• Build a 48-hour thank-you system: no generic receipts—only personal thanks, handwritten notes, and phone calls.
• Report impact. Show donors what their gift did…student camp funded, families served, baptisms celebrated.
• Push recurring giving. Monthly donors have retention rates above 80%. One-time donors: below 20%. The math is obvious.
• Treat new donors like seedlings—early care determines long-term fruit.

Generosity follows gratitude. When people don’t feel valued, their support dries up fast.

3. Follow-Up Speed to First Touch: Delay = Decay

In our world, speed is the new currency. Amazon ships in 24 hours and Uber arrives in five minutes. If your church waits a week to follow up with guests, you’ve already lost them.

Here’s the reality: follow up within 24 hours, and your chance of a second visit can be five times higher than if you wait a week. Five. Times. Higher. [ref]

Growth hides this problem because guests keep coming. But look at your second-visit rate: it’s probably abysmal. People don’t return because they never heard from you.

For years, I’ve said to campus pastors at new campuses to grab the “new here” cards before they are whisked away to a central team member to enter them into a database. Take pictures of each one. Then, on Sunday night, call each of those “new here” guests. Yes, Sunday evening.

Too many churches are too scared to show some passion in the follow-up process. I bet that my dentist has more urgency in ensuring that I book my next plaque removal than your church does in inviting guests to return. Let’s change that.

• Secret shop your own church: fill out a card, see how long it takes to hear back.
• Benchmark goal: 100% of first-time guests contacted within 24 hours.
• Build a system: Handwritten note written on Sunday by volunteers, Sunday afternoon text by campus pastor, Monday morning email from the church, Monday night phone call from a member of the team.
• Train volunteers to share the load; don’t leave it to one overworked staff member.
• Measure weekly: how many cards came in, how many were contacted, and when?

Slow follow-up is the silent killer of momentum. If you can’t respond fast, stop bragging about being “a friendly church.”

4. Kids/Students Capacity Ratio: The Family Filter

Healthy churches consistently see 20–30% of attendance made up of kids and students [ref]. That ratio isn’t just a nice-to-have; it’s the single strongest indicator of long-term health. Below 20%? You’re drawing adults but not reaching families. And without families, you don’t have a future.

You can celebrate growth today…more adults in seats, a buzzing lobby…but if kids aren’t in the mix, you’re quietly aging out. A church that trends older without bringing in the next generation is on a countdown clock.

Parents may love the preaching, music, and atmosphere, but if their kids aren’t excited to come back, the family will drift. Flip it around: when kids are thriving, families stick. Kids aren’t just a ministry; they’re your best retention strategy.

• What percentage of your weekly attendance is under 18? Don’t guess—track it.
• Aim for 20–30%. Below 20% = families slipping through. Above 30% = maxed capacity.
• Compare the ratio year over year. Stable or growing = future. Shrinking = slow death.
• Listen to leavers. Ask why families bail. Nine times out of ten, it’s the kids’ experience.
• Put money where it matters. Staff, space, and resources for next-gen aren’t side projects…they’re the core to the mission.
• Tell the wins. Tell real stories of life change happening in your kids and student ministries. That’s what builds confidence in the future.

Ignore kids and you’re not just losing families—you’re scheduling your church’s funeral.

5. Staffing Leverage: Stop Hiring Doers, Start Hiring Leaders

In small churches, staff do ministry. In large churches, staff equip people to engage in ministry. Fail to make that shift, and you’ll drown.

Here’s the metric: average churches run about 75 attendees per full-time staff. High-performing churches run 100:1 or more. If you’re at 40:1, you’re bloated. [ref]

Growth often hides inefficiency because staff are hustling to keep everything together. But payrolls balloon, volunteers disengage, and eventually the model collapses. You can’t hire your way to 10,000. You must mobilize.

This isn’t just organizational efficiency, it’s obedience. Ephesians 4 reminds us that pastors, teachers, and leaders exist “to equip the saints for the work of ministry.” [ref] The goal isn’t to create a staff of superheroes who do everything; it’s to raise up a church full of ministers.

An insidiously dangerous pattern is when staff start absorbing work that used to be led by volunteers. That’s not progress…it’s regression. It appears that they are helping, but that behavior hinders the church’s development. The flow should run the other way: what staff carry today should eventually be released to volunteers tomorrow. If you see staff pulling ministry back from lay leaders, they’re not empowering the church…they’re shrinking it.

• Audit your ratio: total weekly attendance divided by full-time staff equivalents.
• Measure volunteer engagement: what percentage of adults serve regularly?
• Redefine job descriptions around multiplication, not execution.
• Hire leaders who can build teams, not just talented doers.
• Launch a leadership pipeline: train, empower, and release lay leaders into real authority.

Staff who insist on doing everything aren’t heroes, they’re bottlenecks.

Staff who reach for another hire instead of mobilizing volunteers aren’t scaling ministry, they’re slowing it down.

The Hard Truth and the Way Forward

Growth feels like success. But it’s often camouflage. Behind the buzz of full services and rising giving are the cracks: lost guests, shallow donor bases, families turned off, and staff stretched thin.

Unchecked growth is like a startup with booming revenue and no margin. It looks great on stage but collapses in real life.

The good news: every one of these issues is fixable. But only if leaders stop drinking their own Kool-Aid and start confronting the uncomfortable data.

Your action plan:

1. Run the numbers. Guest capture rate. Donor retention. Follow-up time. Kids ratios. Staffing leverage. Don’t estimate, measure.
2. Set targets. Pick benchmarks that force accountability. 60% guest capture. 24-hour follow-up. 80% room max. 70% serving adults. 100:1 staffing ratio.
3. Assign ownership. Someone on your team is responsible for each metric. Not “everybody.” One person.
4. Communicate urgency. To your board, staff, and congregation. Do not sugarcoat. Growth without health is a future crisis.
5. Invest accordingly. Budget for capacity where it matters: kids’ spaces, follow-up systems, volunteer training. Cut fluff.

Because this isn’t about numbers, it’s about people. Each metric represents individuals who either connected or didn’t, gave again or didn’t, felt welcomed or ignored. These aren’t “corporate KPIs,” they’re kingdom outcomes.

Growth is a gift. But it’s also a test. The question isn’t, “Are you growing?” It’s, “Are you stewarding growth in a way that sustains?”

Don’t let your church’s growth kill its future growth. Build the systems. Strengthen the foundation. Make the shift from tall middle schooler to varsity athlete. Learn the Flop.
