Does the Bible give insight into church growth?

from the old testament

• Church growth is not mentioned in the Old Testament.

from the new testament

• Jesus is the basis for any church's growth. He said, "I will build my church, and the gates of hell shall not prevail against it" (Matthew 16:18). No person can take credit for the church's growth. It is the result of God's work.
• A healthy church naturally grows. Despite persecution, lack of buildings, and other barriers, the first church grew daily (Acts 2:47). While not all New Testament churches grew at this pace, the church naturally grew as people shared the good news of Jesus with friends and neighbors and some of them came to faith in Christ. When we are actively seeking God and loving one another, local churches naturally grow in their faith and number of attendees.
• The early church highly emphasized the essentials of teaching, fellowship, worship, and prayer. These practices are noted in Acts 2:42 and can be seen in many of the congregations started by the apostles in Acts and Paul's letters.
• Growing churches tend to have shared leadership. From Acts 13:1-5 we see that the large, growing church in Antioch had at least five teachers from a diversity of cultural backgrounds. When Paul wrote to Timothy (1 Timothy 3) and Titus (Titus 1), he wanted them to select elders (plural) for local congregations.
• Growing churches focus on multiplication. The church at Antioch prayed and fasted and then sent its top leaders to start new churches (Acts 13:1-5). When the church in Jerusalem was persecuted after Stephen's death, they did not worry about the drop in church attendance. Instead, they scattered to many communities and started new churches.
• The early church's growth was often associated with meeting practical needs. James taught, "Religion that is pure and undefiled before God, the Father, is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world" (James 1:27). He considered both personal purity and serving others as essential in the church. Paul and the other apostles often noted the importance of serving the poor. In fact, history reveals the majority of the early church was composed of the lower economic class of society until the fourth century (though there were notable exceptions).
• Clearly, a church can be large and strong or large and weak. Church size does not equal church health. Revelation 2—3 notes several congregations, some of significant size, that were sinful in some of their practices.

implications for today

Church “growth” is not measured by attendance numbers. A large or fast-growing church is not automatically a healthy church. A healthy church preaches a biblical Gospel and uses biblical practices. What truly matters is that the Gospel is being preached and that the church is faithfully and biblically helping develop believers’ spiritual maturity within the body of Christ.

Only God brings growth, though, as we faithfully steward what He has entrusted to us. This includes the care, discipleship, and nurturing of His people. True growth happens when we prioritize spiritual depth, obedience, and the flourishing of the body of Christ over mere numbers.

Healthy church growth happens when a congregation relies on God as the source of all increase and growth. On our end, we can invest in leaders who shepherd well, and we can welcome newcomers and love others, including meeting tangible needs, creating opportunities for service, and maintaining transparency and accountability. May we seek to faithfully lead the flock entrusted to us or the flock we are a part of, trusting in God’s Spirit to guide, transform, and multiply His people for His glory.
