How do we know the doctrine of service is true?

The Apostle Paul provides compelling evidence for the doctrine of service through the examples of Timothy and Epaphroditus. In Philippians 2:19-30, Paul notes that Timothy genuinely cares for the congregation, demonstrating the heart of a true servant. Additionally, Epaphroditus willingly took on a challenging journey to minister to Paul's needs, exemplifying that serving others is integral to the Christian life. These examples illustrate that service is not merely a suggestion but a commanded practice rooted in Christ's teaching and modeled by his disciples.
