The third letter of John is the shortest book in the New Testament, yet it pulses with a vitality and urgency that speaks directly to the heartbeat of the local church. While 2 John warns us about who we should not let into our fellowship, 3 John pivots to show us exactly who we should be championing. It is a letter about the plumbing of the early church, the hospitality, the support systems, and the interpersonal dynamics that allowed the Gospel to spread like wildfire across the Roman Empire.
In this chapter of The Way of the Word, we are diving deep into the 15 verses of 3 John. We are going to look at the three men who define the landscape of this letter: Gaius the faithful, Diotrephes the proud, and Demetrius the commended. Through their lives, we discover a blueprint for what it means to walk in truth and how we can foster a fellowship that is both doctrinally sound and radically hospitable.
The Beloved Gaius: A Soul in Good Health
The letter opens with a greeting that has become one of the most famous benedictions in the Bible: "Beloved, I pray that all may go well with you and that you may be in good health, as it goes well with your soul" (3 John 1:2).
John is writing to his dear friend Gaius. While we don't know exactly which Gaius this is, the name was as common in the first century as "John" is today, we know his character. He is "beloved in truth." For John, truth isn't just a set of propositions you agree with; it’s a person you walk with.
Notice the priority John sets here. He prays for Gaius’s physical health and his external circumstances to match the health of his soul. This is a profound reversal of how the world usually operates. Most people spend their lives trying to make their external world healthy, better bank accounts, better bodies, better reputations, while their souls are withered and malnourished. John looks at Gaius and says, "Gaius, your soul is so vibrant, so full of the Spirit, and so aligned with the truth, that I hope your body can keep up with it."
What does it mean to have a healthy soul? In the context of 3 John, soul health is synonymous with "walking in the truth." Verse 3 tells us that brothers came and testified to Gaius’s truth. They didn't just say he was a nice guy; they said the truth was in him.
Walking in the Truth: The Greatest Joy
John writes in verse 4: "I have no greater joy than to hear that my children are walking in the truth."
For any spiritual leader, pastor, or parent, these words resonate with a deep, guttural truth. Success in the Kingdom of God isn't measured by the size of the building or the number of followers on a social media platform. It is measured by the steady, faithful walk of those we have mentored.
To "walk in the truth" implies movement and consistency. It means that the Word of God has moved from our heads to our feet. It means that when no one is watching, our steps are still aligned with the character of Christ. Gaius wasn't a "Sunday-only" Christian. His life was a consistent testimony to the reality of the Gospel.
In our modern culture, "truth" is often treated as something subjective, "my truth" or "your truth." But for John, Truth is objective and grounded in the person of Jesus Christ. Walking in truth means living in accordance with the reality that Jesus is Lord, that the Spirit is our Comforter, and that we are called to love one another as He loved us.
The Mission of Hospitality: Fellow Workers for the Truth
The core conflict and the core commendation of this letter center on hospitality. In the first century, traveling missionaries and teachers didn't have hotels or secure communication lines. They relied entirely on the hospitality of local believers.
John praises Gaius for his "faithful effort" in supporting these brothers, even though they were strangers to him (v. 5). This is where the rubber meets the road in Christian fellowship. It’s one thing to be kind to your friends; it’s quite another to open your home, your pantry, and your wallet to people you don't know, simply because they come "in the Name."
The brothers who visited Gaius testified before the church about his love. John encourages Gaius to continue this work, saying, "You will do well to send them on their journey in a manner worthy of God" (v. 6).
What does it mean to treat a guest "in a manner worthy of God"? It means providing for them not just with the bare minimum, but with the abundance and care that reflects God’s own heart. In the Assemblies of God tradition, we have long emphasized the importance of missions. We understand that not everyone is called to "go" across the ocean, but everyone is called to be a "fellow worker for the truth" (v. 8).
When you support a missionary, when you host a traveling evangelist, or when you provide for the needs of those working in the harvest field, you aren't just doing a good deed. You are actively participating in their work. You are a co-laborer. Their converts are, in a spiritual sense, your converts. Their fruit is your fruit. Hospitality is a missional weapon.
The Warning of Diotrephes: The Love of Preeminence
If Gaius is the model of a healthy soul, Diotrephes is the warning of a diseased one. John doesn't mince words: "I have written something to the church, but Diotrephes, who likes to put himself first, does not acknowledge our authority" (v. 9).
The Greek phrase for "likes to put himself first" is philoproteuon. It describes a person who craves preeminence. This is the ultimate spiritual cancer. While Gaius was focused on the Name of Jesus, Diotrephes was focused on the name of Diotrephes.
Diotrephes represents the danger of authoritarian, unaccountable leadership. He didn't just ignore John; he "gossiped maliciously" against him. He refused to welcome the brothers who were sent by John, and he even went so far as to put out of the church anyone who tried to show them hospitality.
Think about the tragedy of this situation. Diotrephes was using the structures of the church to block the work of the Gospel. He was so protective of his own "turf" that he became an enemy of the truth he claimed to serve.
In every generation, the church faces the "Diotrephes Spirit." It shows up whenever a leader becomes more concerned with their own control than with Christ’s Commission. It shows up when a church becomes a closed circle, suspicious of outsiders and resistant to the wider fellowship of the body of Christ. John’s response is clear: when he comes, he will bring these deeds to light. Truth cannot coexist with hidden agendas and prideful control.
The Commendation of Demetrius: A Good Testimony
In contrast to Diotrephes, John introduces Demetrius. We don't know much about him, but John says he "has received a good testimony from everyone, and from the truth itself" (v. 12).
Demetrius was likely the person carrying this letter to Gaius. By commending him, John is providing a "letter of recommendation," a standard practice in the early church to ensure that false teachers didn't slip in.
Demetrius is a man of integrity. His life matches the truth so closely that John says "the truth itself" testifies for him. If you held the Word of God up against the life of Demetrius, they would line up. That is the goal for every believer. We want our lives to be so saturated with the Spirit that we don't need to argue for our own reputation, our character does the talking for us.
The Theology of Fellowship: Face to Face
John concludes his letter by acknowledging that he has much more to say, but he doesn't want to use "pen and ink." He says, "I hope to see you soon, and we will talk face to face" (v. 14).
This echoes the ending of 2 John and reminds us of a fundamental biblical truth: technology and written communication are wonderful, but they are no substitute for personal presence. Fellowship is meant to be "face to face."
In an age of digital discipleship and online streaming, we must never lose sight of the "one anothers" of Scripture. We cannot wash one another's feet over Zoom. We cannot bear one another's burdens through a text message alone. The "manner worthy of God" hospitality John advocates for requires skin in the game. It requires being in the same room, sharing the same table, and looking into the same eyes.
Hospitality as a Spiritual Discipline
Why does John spend so much time on hospitality in such a short letter? Because hospitality is the outward expression of an inward grace. It is the practical outworking of the Gospel.
When we welcome others, we are reflecting the hospitality of God, who welcomed us when we were "strangers and aliens." God didn't just send us a letter; He sent His Son to live among us. He prepared a table for us in the presence of our enemies. He invited us into His family and gave us a seat at His banquet.
For the church to be healthy, it must be a place where "strangers" become "brothers." This requires a level of vulnerability and sacrifice that Diotrephes was unwilling to give, but that Gaius gave gladly.
Practical Steps for Walking in Truth
How do we apply the lessons of 3 John to our lives today?
Conduct a "Soul Health" Check: If your physical health were exactly proportional to your spiritual health, would you be fit and strong, or would you be in the hospital? Spend time in the Word and in prayer, asking the Holy Spirit to strengthen your inner man.
Practice Intentional Hospitality: Look for opportunities to support those who are "going out in the Name." Whether it’s supporting a missionary, hosting a small group, or simply inviting a newcomer at church to lunch, make hospitality a regular part of your rhythm.
Reject the Love of Preeminence: Guard your heart against the desire to be first. Cultivate the spirit of a servant. If you find yourself becoming defensive of your "position" or "territory," take it to the Lord in repentance.
Value Personal Fellowship: Don't let digital connection replace physical community. Make it a priority to meet "face to face" with other believers, sharing life and truth together.
Be a Demetrius: Strive to have a testimony that is consistent with the truth. Let your "yes" be "yes" and your "no" be "no." Live in such a way that if someone looked at your life, they would see a reflection of the Gospel.
The Call to Fellowship
3 John reminds us that we are part of something much bigger than ourselves. We are part of a global, historical, Spirit-empowered movement. We are "fellow workers for the truth."
When we walk in the truth, when we support one another, and when we lead with humility, we create a fellowship that the world cannot ignore. We create a place where the love of God is visible, tangible, and transformational.
Gaius was a simple man who did a "faithful effort" for the brothers. He didn't need to be an apostle to be a hero of the faith. He just needed to be a friend of the truth. May we all be like Gaius: souls in good health, walking in the light, and opening our hearts to the mission of God.
Reflection Questions
If John were to write a letter to you today, would he say that it goes "well with your soul"? What areas of your spiritual life need the most attention?
In what ways can you become a "fellow worker for the truth" in your local church or through missions support?
Have you ever encountered a "Diotrephes" spirit in yourself or others? How can we cultivate humility and servant leadership in our communities?
What does it mean to you to "send someone on their journey in a manner worthy of God"? How does this change the way you think about giving?
How can you make "face to face" fellowship a greater priority in your life this week?
A Prayer for Fellowship
Heavenly Father, we thank You for the truth that sets us free. We thank You for the brothers and sisters You have placed in our lives to walk alongside us. Help us, like Gaius, to be people of hospitality and faithfulness. Guard our hearts against pride and the desire for preeminence. May our lives be a consistent testimony to Your grace, and may we always be found walking in the truth. Strengthen our local churches to be places of radical welcome and missional support. In the mighty Name of Jesus, Amen.
