The True Foundation of Church Growth: A Reflection on Age, Diversity, and God’s Centrality

A single post on social media can spark profound reflections on critical topics, and one such post has led to a deep contemplation of church growth and sustainability. The popular notion that a church will die if it does not invest in young people has circulated widely, but upon deeper consideration, it is clear that this perspective is limited. While youth investment is important, it is far from the only factor that sustains a thriving church. To fully understand the nature of church growth, we must look beyond age demographics and return to biblical principles.

This topic has been particularly resonant for me after Bible Study on Wednesday, where Rev. Jarkeer touched on the significance of diversity in the church. His insights added depth to my thoughts, emphasizing that the church’s growth cannot rely on a single group. The church, as the body of Christ, must serve all people, regardless of age or background, in alignment with God’s vision of unity and diversity.

The nature of the church is not to cater to any single demographic—whether young or old. The church, as the body of Christ, is called to minister to all people, regardless of age. Investing in youth is valuable, as they are indeed the future, but this does not negate the importance of ministering to people at every stage of life. In God’s eyes, souls are not limited by age brackets. The Great Commission, given by Jesus in Matthew 28:19-20, commands the church to make disciples of all nations and peoples: “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you.” This charge encompasses all generations, not just the youth.

A church’s true growth stems from keeping God as the center. When the church places its primary focus on glorifying God, teaching His Word, and making disciples of all people, it thrives. As Jesus said in John 12:32, “And I, when I am lifted up from the earth, will draw all people to myself.” The church must first be centered on lifting up Christ, and in doing so, people from all walks of life will be drawn to Him. The concept that “sheep beget sheep,” which suggests that people draw others to Christ, applies to all believers—young and old, rich and poor, and from all backgrounds. When the focus is on soul-winning and building on the foundation of Christ, the church grows organically.

One of the greatest dangers of focusing solely on one demographic, such as young people, is that it neglects the diversity within the body of Christ. The Apostle Paul’s teaching in 1 Corinthians 12:12-27 provides a powerful metaphor for the church as one body with many parts. Paul explains that the church is made up of many members, each with different gifts and purposes, but all are unified under one Spirit. Verse 12 states, “For just as the body is one and has many members, and all the members of the body, though many, are one body, so it is with Christ.” This passage underscores the richness of diversity within the church. By focusing only on one group, such as the youth, the church misses the broader vision of how God intends for His body to function in unity, with each part contributing to the strength and growth of the whole.

The heart of the church is not determined by age, but by its focus on Christ and its mission to reach all people with the gospel. The psalmist reminds us in Psalm 127:1, “Unless the Lord builds the house, those who build it labor in vain.” This verse highlights the reality that if God is not the foundation of the church, no amount of programming or targeted demographic outreach will sustain it. A church that loses its focus on Christ loses its purpose and, ultimately, its vitality.

In conclusion, the sustainability of the church does not rest solely on investing in youth but on investing in all people, with Christ as the foundation. When a church commits to glorifying God, teaching His Word, and making disciples across all generations, it reflects the unity and diversity that God intended for His body. A church built on the solid rock of Christ will thrive, not because it caters to one age group, but because it is rooted in the eternal truths of the gospel and the power of God.
