How to Double Your Church in 90 Days: Proven Strategies to Break Church Growth Barriers

How to Double Your Church in 90 Days is written directly for pastors who want practical strategies for increasing attendance. Paul Anthony Hardin offers practical ideas for clarifying mission and vision, developing leaders, improving Sunday services, strengthening children's ministry, increasing hospitality, planning sermon series, hosting events, and building a digital presence, and he argues that many older church-growth practices have become ineffective and that leaders must adapt to changes in communication, marketing, hospitality, and the way people first encounter a church.

There is genuinely useful material here. The idea that growing the leader can help grow the church is sound. Churches benefit from clearly defining their mission, vision, and values, improving their children's spaces, planning sermon series intentionally, connecting worship and small groups to the message, and creating an environment where members feel confident inviting others. Clean facilities, welcoming volunteers, free coffee, organized services, and valuable sermons may seem small, but they communicate care. His reminder to remove consistently unfriendly ushers is blunt, but fair. Hospitality matters.

The book is also right that a church's digital presence has become its front door. Many people will visit a website or social media page before attending in person. The basic explanations of online advertising may help pastors unfamiliar with digital marketing, although the limited depth could also lead inexperienced churches to spend money on poorly designed campaigns. That concern is heightened by the repeated promotion of additional paid coaching, courses, software, and resources. The frequent promotion of these made the book sometimes feel more like an introduction to a sales system than a complete ministry resource.

My greater concern is the theology beneath the strategy. The book often treats continuous growth in first-time visitors as the solution to nearly every church problem. At one point, connect cards are described as the primary goal of a service aside from conversions. Prayer is included, but it feels more like one strategy among many than the foundation of ministry.

The claim that a steady flow of first-time guests solves nearly every church problem places too much confidence in traffic and too little in discipleship. The author is blunt and direct that this is his stance, stating clearly: "traffic is the solution to all the problems within a church." Taking this approach will inevitably lead current members to begin to feel like tools for attracting future members rather than people entrusted to the church's care.

Scripture certainly supports evangelism, wise planning, hospitality, excellence, and removing unnecessary barriers that keep people from hearing the gospel. A growing church may gain greater opportunities to serve its community. But numerical growth is not the only evidence of faithfulness. A small church that disciples its members, cares for struggling families, teaches truth, and serves its neighborhood may be deeply successful without doubling in 90 days. Paul planted, Apollos watered, but God gave the increase.

This book offers strong ideas in two areas: helping first-time guests want to return and helping churches reach people who have not yet attended. The individual strategies are often reasonable and sometimes excellent. The problem is not that the ideas are necessarily unbiblical; it is that the ideology connecting them can make church growth feel too dependent on marketing, execution, and an endless demand for more people.

Pastors can benefit from this book, but they should read it with discernment. Vision can harness potential, strategy can improve ministry, and leaders should create churches where people feel safe, valued, and welcomed. Still, the church is not a business, attendance is not the same as discipleship, and growth should never become a substitute for faithfulness. Pastors can benefit from its practical observations while still questioning its assumptions. Churches should plan, communicate, improve, and execute with excellence, but strategy must remain a servant of the mission rather than becoming the mission itself. The goal is not simply a larger church. It is a faithful church that helps people know Christ, grow in Him, and serve others.
