3 John (3 Jn)
Book 25 of the New Testament, having 1 chapter. Written by the apostle John about AD 90. Time to read: 5 mins.
Key people
John, Gaius, Diotrephes, Demetrius
Summary
It was addressed to Gaius, a prominent Christian, to commend him for his hospitality. His actions and lifestyle are in contrast to another leader's bad example – Diotrephes who misused his position and authority. Another person, "Demetrius is well spoken of by everyone – and even by the truth itself", hence a good example (3 Jn 1:12).
Central message
The central message of 3 John revolves around the importance of living a life that reflects God's truth and love. John emphasizes that our daily choices and consistent habits shape our character and reputation, which in turn impacts those around us. The letter presents two contrasting examples: Gaius, who exemplifies faithful hospitality and love, and Diotrephes, who represents pride, selfish ambition, and a desire for control. John's exhortation is clear: "Dear friend, do not imitate what is evil but what is good" (3 Jn 1:11).
This message challenges us to examine our own lives and ask whether we are following the pattern of Gaius or Diotrephes. Are we using our resources, influence, and opportunities to serve others and advance God's kingdom, or are we primarily concerned with our own status and recognition? True Christian character is revealed not in grand gestures but in the everyday choices to show kindness, extend hospitality, and support fellow believers in their ministries.
John also highlights the importance of truth as the foundation for our actions. Demetrius is commended not just for being popular, but because "he is well spoken of by everyone—and even by the truth itself" (3 Jn 1:12). This suggests that genuine Christian character aligns with divine truth and is validated by it. Our reputation among people matters, but what matters more is whether our lives are in harmony with God's truth.
In a world that often values power, status, and self-promotion, 3 John calls us to a different way of living—one marked by humble service, genuine love, and faithfulness to truth. By choosing to "do what is good," we not only please God but also become agents of His grace and love in a world that desperately needs both.
Important passages and reflections
* "Dear friend, you are faithful in what you are doing for the brothers, inviting them into your home" (3 Jn 1:5). Hospitality – making your home available to serve the practical needs of others – is a vital and powerful tool to minister to non-Christians and believers, strangers or friends alike. Opening up your home is opening up your heart in love, showing you care. Meals or accommodation doesn't have to be elaborate – it is a tangible expression of meeting a need and sharing what we have been blessed with. In today's individualistic society such welcoming action displays that we value people and can touch them deeply as we give generously, outworking the grace of God. Lasting friendships are often formed. Am I developing and practicing this gift of friendship by serving my fellow humans with the love of Christ?
Application points
- Actively practice hospitality by inviting others into your home, regardless of social status or familiarity. Make your home a place of welcome and refreshment for both believers and non-believers. This could mean hosting small group meetings, inviting newcomers for meals, or offering temporary accommodation to those in need. True hospitality isn't about perfection but about generosity and openness. By sharing what God has given you—your space, time, and resources—you demonstrate Christ's love in tangible ways. Consider creating a regular rhythm of hospitality, perhaps a monthly dinner for church members or neighbors, and pray for opportunities to build meaningful relationships through these gatherings.
- Examine your leadership and influence—ensure it builds others up rather than asserting control. Reflect on whether your actions promote unity and encouragement or personal ambition and domination like Diotrephes. Healthy leadership listens, empowers, and celebrates others' contributions rather than seeking recognition. Are you supporting fellow believers in their ministries? Do you welcome input from others or shut down differing perspectives? Commit to leading with humility, always asking whether your influence helps others grow in faith and service. Seek feedback from trusted peers about your leadership style and be willing to make changes that align with biblical principles of servant leadership.
- Support and affirm those who live out the truth, like Demetrius, to strengthen the body of Christ. Identify individuals in your community who consistently demonstrate integrity, faithfulness, and love in their words and actions. Take intentional steps to encourage them—through words of appreciation, practical help, or public recognition when appropriate. This could involve writing thank-you notes to volunteers, sharing testimonies of faithful service during meetings, or partnering with them in ministry initiatives. When we affirm those who embody Christian truth, we reinforce positive examples and inspire others to follow suit, creating a culture of mutual edification and spiritual growth.
