Measured by the Sowing: Church Health Amidst Decline

“Who can change the sinner’s heart?”

Imagine if Jesus told the parable of the sower as if he were a church health guru:

The seed is the word of God. Those ones that fell along the path, snatched up by the birds? They heard the word, but your preaching wasn’t enthralling enough, and so the devil got ‘em. And the ones on the rocky soil? Well, what did you expect? If you call people to repentance, to be completely reconstructed by God’s grace on his terms, they’ll walk away. Duh. And then of course the ones that fell among the thorns couldn’t find the perfect programming tailored for their niche demographic at your church, and so they didn’t mature.

This is preposterous! This absurdity is not how Jesus talks.

And yet something very much like this logic has quietly settled into parts of the modern, evangelical (and dare I say it?), Reformed church. When the gospel does not appear to “work,” we assume the problem must lie in the delivery system—insufficiently compelling preaching, inadequate programming, or a failure to craft the right strategy. The implication is subtle but powerful: if we would only improve the machinery of ministry, the harvest would follow.

But that is not how Jesus tells the story.
Part of the reason this logic feels persuasive is the cultural moment in which the American church now finds itself. Over the past several decades, the growth of the American church has slowed and, in many places, reversed. Christians—whether broadly identified, Protestant, or evangelical—have significantly declined as a percentage of the population, while the religiously unaffiliated, the “nones,” have grown rapidly. What was once culturally normal has become increasingly marginal. Participation in church life is no longer a cultural default. It is something people must consciously choose, and the number opting in has diminished.

These changes naturally provoke angst within the church. Pastors and congregations look at shrinking numbers, aging memberships, and a less receptive public square and ask an understandable question: What should we do? How do we reach the world? How do we grow the church?

Those are important questions. If the aim is to bring people to faith in Jesus Christ and to build up the saints, then thinking carefully about ministry is not optional. Stewardship matters and resources matter; volunteers, buildings, skills, opportunities are all gifts from God and ought to be used wisely. But in seasons of decline there is a particular temptation to make the church’s efforts the primary emphases on gospel health and growth.

What does this look like? First, leveraging resources effectively becomes the definition of gospel faithfulness. Ministry skill and programmatic excellence becomes the standard by which faithfulness to Christ is assessed. Second, the success of programs and initiatives becomes the chief evidence that the gospel is advancing. The ordinary means of grace—Word, sacrament, prayer—fade quietly into the background. They may remain present, but when the church talks about its ministry, its other activities and features are the things predominantly celebrated and pointed to as the reason for health. Third, evaluations of church health begin to focus primarily on these external measures. When churches fail to grow numerically, the explanation offered is often moral rather than circumstantial: You must not be doing something right.

The conclusion follows quickly. If your church is not growing, it must be because you are not being faithful.
Now, growth is good. Scripture repeatedly celebrates the expansion of the church: “The Lord added to their number day by day those who were being saved” is not a one-time comment in Acts. We rightly rejoice when congregations grow, sinners repent, and the gospel bears visible fruit.

But growth is one possible symptom of faithfulness, not its axiomatic definition. Gospel faithfulness does not guarantee numerical increase. There may be a correlation between the two, but Scripture never promises automatic causation. The kingdom of God is not a formula.

It’s common to hear Gamaliel’s counsel from Acts 5:38-39 invoked: If this work is of man it will fail, but if it is of God it will succeed. These words are frequently quoted as a kind of ministry principle: if something grows, it must be of God; if it’s not growing, it must be because it’s not faithful to God. This principle baptizes church health and growth tactics on the basis of numerical growth.

But as John Calvin noted, Gamaliel’s argument is logically specious. Gamaliel has a fallacies premise, even if his conclusion about the early church is correct. He assumes that if something is faithful to God it will necessarily appear successful on worldly terms. But this the literal opposite of Peter’s earlier assertion in Acts 5:29 “We must obey God rather than man”. Peter is declaring that faithfulness to God, no matter the opposition or evident success, is found in obedience to and following God. What makes something “of God” is not whether it appears outwardly blessed, but whether it faithfully follows his revealed call.

Gamaliel reasons backward: if something succeeds, it must be from God. Peter reasons from God’s will: if God commands and we follow, no matter what happens next, what we’re doing is of God.

Of course, the opposite mistake can also occur, which sometimes Presbyterian and Reformed churches fall into, namely that numerical modesty is a badge of pious fidelity. That conclusion is just as misguided. The early church was faithful — and grew dramatically. Growth may come. Or it may not.

The question to ask is this: What has God called the church to do, even now, amid decline?

Jesus answers that question in the parable of the sower itself. The church’s responsibility is to sow, sow, sow. No matter the soil, no matter the season, share and proclaim the gospel wherever God opens doors.

The church’s task is not to engineer the harvest. The Bible uses agricultural imagery for a reason. The sower can plant, water, tend the soil, but the actual gift of life lies beyond their control. So it is with the gospel. The church waters and plants, but God gives the growth.

So who can change the sinner’s heart? The Holy Spirit alone.

Salvation belongs to the Lord. The church knows that salvation is by the sovereign grace of God, but especially when facing numerical decline and cultural hostility, we are tempted to reach for our programmatic tools to assure ourselves of gospel success. Indeed, sometimes we Presbyterian and Reformed folk behave as though even the ordinary means of grace function automatically for ministerial growth. But the means are means of God’s grace.

God’s promise is not: If you administer the Word, I will inevitably convert people.
God’s promise is: When I save people, it is through these means.

The church proclaims; God regenerates. The church sows; God gives the growth.

At the same time, Christ’s parable does not encourage carelessness. Farmers who scatter seed indiscriminately without paying attention to their fields will not farm for long. In that sense, many voices in the church health conversation rightly emphasize something important: faithful sowing includes knowing the soil.

We cannot see into the hidden recesses of the human heart, but we can know the people and communities among whom God has placed us. We can learn their questions, their fears, their cultural assumptions. We can grow in skill as communicators of the gospel. We can structure programs that effectively connect with our neighbors. Faithfulness includes knowing, loving, and caring for the actual people God has brought near us. Excellence in stewardship is a Christian and ministerial duty.

For example, Vice Admiral John Scott Redd has proposed a helpful framework for leadership called the VECTOR model: vision, excellence, character, teamwork, organization, and respect. Properly understood, these principles simply describe wise stewardship. They are ways of organization our efforts so that we can better know, love, and serve those around us. Applied to ministry, such frameworks can help congregations implement the ordinary rhythms of church life thoughtfully and well. Preaching can be clearers, hospitality can be warmer, service to others better organized. But even here the order must remain clear: these things support the sowing, they do not replace it.

Jesus tells another pair of parables that illuminate this point. In Matthew 25 and Luke 19, a master departs on a journey and entrusts money to several servants. Two of them invest what they have received and double it. A third, afraid of failure, hides the money in the ground. When the master returns, he praises the first two servants: “Well done, good and faithful servant… enter into the joy of your master.” The third servant, who buried the gift, is rebuked.

Jesus’ lesson is not that faithful investment guarantees a predictable return on investment in this life. The servants who doubled their money did not know the outcome beforehand. They acted because the master had entrusted something valuable to them.

That’s the point.

The church has been entrusted with the gospel of Jesus Christ. Faithfulness means investing it—sowing it widely and boldly. The guaranteed return is not numerical success. The guaranteed return is the joy of the master. No matter how sophisticated our programs become, no matter how refined our strategies appear, the measure of faithfulness remains the same. Did we sow the word? Did we proclaim Christ? Did we obey God rather than men?
Anxiety about the future of the church can easily lead to frantic activity. The temptation is to rely on gimmicks, worldly tactics, or strategic brilliance to secure the church’s survival. But the church is never sustained by such things.

Christ himself promised that the gates of hell would not prevail against his church. That promise does not eliminate seasons of difficulty, decline, or marginalization. Yet it anchors the church’s hope somewhere far more stable than cultural approval or numerical trends. The calling of the church remains beautifully simple.
God is the Lord of the harvest. Sow the word, and trust in God to give the growth.
