How do we know the importance of community among believers?

The importance of community is well-documented throughout the New Testament, especially in the relationships fostered by figures like Paul, Priscila, and Aquila. In Romans 16, for instance, Paul sends greetings to several individuals, which indicates a strong sense of community and belonging. It is through these interactions that believers are encouraged, supported, and challenged in their faith. Moreover, sharing life together—through greetings, hospitality, and mutual encouragement—reflects the love of Christ and fulfills the command to bear one another's burdens, as mentioned in Galatians 6:2. The church is not merely an assembly of individuals but a body that functions best when all parts are working in harmony.
