Imagine signing up for a gym membership and paying your dues but never attending a class, joining a training group, or building relationships with other members. You might occasionally walk through the doors, observe others working out, and then leave without engaging in any meaningful exercise. Sound absurd? Yet this is exactly how many Christians approach their relationship with the local church.
Just as physical fitness flourishes in a community setting, spiritual fitness was designed by God to develop within the context of local church relationships. The writer of Hebrews makes this clear: “Let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another” (Heb 10:24-25). The emphasis here isn’t just on attendance but on active participation in each other’s spiritual growth.
Think of your local church as God’s designated spiritual fitness center. It’s not a showcase for spiritual champions but a training ground for everyday disciples. The Apostle Paul describes the church as a body where “when each part is working properly,” it “makes the body grow so that it builds itself up in love” (Eph 4:16). Every member has a role to play in this mutual strengthening.
Some might object, “But the church is full of imperfect people!” Exactly—and that’s precisely the point. God intentionally places us in community with other spiritually growing (and sometimes struggling) believers because that’s where real spiritual development happens. The church isn’t a museum for saints but a hospital for sinners, a training center where spiritually weak people become strong through Christ's power working in community.
Consider how a good fitness center operates. It offers various programs for different needs: group classes, personal training, specialized equipment, and nutrition guidance. Similarly, a healthy church provides multiple contexts for spiritual growth. Sunday worship services offer corporate praise and teaching. Small groups provide intimate settings for Bible study and prayer. Ministry teams create opportunities for service and leadership development. One-on-one discipleship relationships foster personal accountability and mentoring.
The early church demonstrated this comprehensive approach to spiritual fitness. “They devoted themselves to the apostles’ teaching and the fellowship, to the breaking of bread and the prayers” (Acts 2:42). Notice the combination of learning, relationships, shared meals, and corporate prayer. This wasn’t a once-a-week commitment but a lifestyle of spiritual training in community.
Just as serious athletes know the value of workout partners who push them toward their goals, Christians need spiritual training partners. “Iron sharpens iron, and one man sharpens another” (Prov 27:17). When we’re struggling with temptation, dealing with doubts, or facing life challenges, these relationships provide the encouragement and accountability we need to stay spiritually fit.
But here’s the challenging truth: these benefits only come through active participation. Simply attending Sunday services, while important, is like showing up at the gym but never breaking a sweat. Real spiritual growth happens when we commit to doing life together—joining a small group, serving in ministry, building friendships, sharing meals, praying together, and walking alongside each other through life’s ups and downs.
This kind of commitment can feel intimidating. Maybe you’ve been hurt by church experiences in the past. Maybe the thought of vulnerability makes you uncomfortable. Maybe your schedule already feels overwhelming. But consider Paul’s vision for church community: “Speaking the truth in love, we are to grow up in every way into him who is the head, into Christ” (Eph 4:15). This growth happens as we risk being known, serve others despite our inadequacies, and prioritize spiritual relationships.
The beautiful thing about church commitment is that you don’t have to be spiritually fit to start. Just as a gym welcomes people at all fitness levels, the church is for people at every stage of spiritual development. What matters is taking the first step: moving beyond mere attendance to meaningful engagement. Join a small group. Volunteer for a ministry team. Invite someone to coffee. Start building those relationships that God will use to shape your spiritual life.
Remember, spiritual fitness isn’t a solo sport. God designed us to grow together, each member contributing to the health of the whole body. Your local church, despite its imperfections, is God's chosen “fitness center” for your spiritual development. Don’t settle for being an occasional observer. Step into the training ground God has provided, and watch how he uses community to transform your spiritual life.
The time to start is now. Your spiritual fitness—and the fitness of your fellow believers—depends on it.
