What does the Bible say about serving one another?

In Galatians 5:13-15, Paul instructs believers to serve one another through love, framing this action as a response to the freedom we have in Christ. This love is central to the identity of Christians and aligns with the fulfillment of the law, which commands us to love our neighbor as ourselves. By serving others, we indeed reflect the grace shown to us by Christ, manifesting His love in practical ways. Furthermore, serving one another fosters harmony and counters division within the body of Christ, which Paul warns against by highlighting the dangers of biting and devouring one another.
