How to Use This Commentary
Third John closes by shifting our attention from a negative example to a positive one. After warning the church about the pride of Diotrephes, John encourages believers to imitate a faithful man named Demetrius. In doing so, he reminds us that the Christian life is learned not only through biblical teaching but also through godly examples worth following.
Read the letter in three movements: (1) walking in the truth through faithful gospel partnership (1–8), (2) the danger of pride and self-centered leadership (9–10), and (3) following godly examples who reflect Christ (11–15).
Every believer influences someone. Parents shape children. Mature Christians disciple younger believers. Pastors shepherd congregations. Friends encourage one another. Whether we realize it or not, our lives are teaching others what it looks like to follow Jesus. John’s closing words challenge us to carefully consider whose example we follow—and what kind of example we are becoming.
John also reminds us that relationships matter in the Christian life. His desire to visit face-to-face instead of communicating only through letters shows that discipleship is deeply personal. While written truth is essential, God designed believers to encourage, correct, and strengthen one another through genuine fellowship.
Key: Third John 11–15 teaches that mature believers reject evil, imitate what is good, cultivate a Christlike reputation, and encourage one another through authentic Christian relationships.
A Quick Look: 3 John 11–15
Big Idea: Mature believers reject evil, imitate what is good, and leave behind a life that points others to Jesus Christ.
Why this matters: Every Christian is following someone’s example, and every Christian is setting an example for someone else. In a world where influence is often measured by popularity, success, or social media following, John reminds us that God values something far more important—godly character. After exposing the destructive example of Diotrephes, John points to Demetrius as a believer whose life reflected the truth of the gospel. His reputation wasn’t built on self-promotion but on faithful obedience. John’s closing words also remind us that Christianity is lived out in authentic relationships where believers encourage, strengthen, and disciple one another face to face.

A Simple Explanation (3 John 11–15)
11 — Follow Good Examples, Not Bad Ones.
After describing the pride of Diotrephes, John gives a simple but powerful command: “Do not imitate what is evil, but what is good.” Rather than becoming consumed with false examples, believers are called to intentionally follow those whose lives reflect Christ. John explains that those who do good demonstrate that they belong to God, while those who continually practice evil reveal that they have not truly known Him.
Meaning: Every life points in a direction. Our choices reveal the influence shaping our hearts. While good works do not earn salvation, they demonstrate the transforming work of God in the life of someone who has genuinely come to know Him.
Application: Carefully consider who is influencing your life. Choose role models whose character reflects Christ rather than those who merely possess talent, success, or popularity.
12 — A Godly Reputation Is Built Through Faithful Living.
John introduces Demetrius as a man who has earned the respect of everyone who knows him. More importantly, John says that “the truth itself” speaks well of him. His life consistently matched the message he believed. John even adds his own testimony, assuring Gaius that Demetrius is trustworthy.
Meaning: A godly reputation is not built through self-promotion but through years of faithful obedience. Character carries more weight than charisma, and integrity leaves a lasting testimony that points others toward Christ.
Application: Instead of asking, “How can I become more influential?” ask, “What kind of reputation am I building?” Live today in a way that causes others to see the transforming power of the gospel in your life.
13–14 — Some Things Are Best Shared Face to Face.
John tells Gaius that he has much more he would like to write, but he prefers to speak with him in person. While letters were valuable, they could never fully replace personal fellowship. John longed to encourage, strengthen, and minister to Gaius face to face.
Meaning: God designed Christianity to be lived in community. Written communication is helpful, but spiritual growth flourishes through personal relationships where believers worship, encourage, teach, correct, and pray for one another.
Application: Don’t allow technology or busy schedules to replace meaningful Christian fellowship. Make time to meet with other believers, encourage one another, and invest in relationships that strengthen your faith.
15 — Peace and Friendship Mark Healthy Christian Community.
John closes his letter by wishing peace to Gaius and sending greetings from mutual friends. He even asks that each friend be greeted by name, demonstrating the personal nature of Christian fellowship. The gospel creates more than an organization—it creates a family united in Christ.
Meaning: Healthy churches are built on relationships shaped by the peace of Christ. The gospel not only reconciles us to God but also unites believers together as brothers and sisters who genuinely care for one another.
Application: Take time to encourage fellow believers personally. A simple conversation, phone call, handwritten note, or prayer can strengthen someone’s faith and remind them they are part of God’s family.
Bridge: John concludes his letter by shifting our attention away from the pride of Diotrephes and toward the faithfulness of Demetrius. Rather than allowing evil examples to shape our lives, God calls us to imitate what is good, cultivate Christlike character, and invest in relationships that help others faithfully walk in the truth. Healthy discipleship isn’t merely taught—it is lived out before others, one faithful life at a time.
A Deeper Dive: Following Faithful Examples and Finishing Well
1) Everyone Is Following Someone
John’s command in verse 11 assumes an important reality: people naturally learn by imitation. Whether we realize it or not, we are constantly influenced by the examples around us. Children imitate parents. New believers watch mature Christians. Church members observe their leaders. Friends influence one another through their words, attitudes, and actions.
That is why John does not merely say, “Avoid evil.” He says, “Do not imitate what is evil, but what is good.” The Christian life is not lived in isolation. We become like the people we admire, follow, and spend time with.
Scripture repeatedly calls believers to imitate godly examples. Paul encouraged churches to imitate him as he imitated Christ. The writer of Hebrews instructed believers to consider the outcome of faithful leaders and imitate their faith. John’s command fits within this same biblical pattern: learn from people whose lives consistently reflect Jesus.
Application: Ask yourself, “Who is shaping the way I think, speak, and live?” Intentionally spend time with people whose love for Christ challenges you to grow in your own faith.
2) Good Works Reveal a Changed Heart
John writes that the one who does good is from God, while the one who does evil has not seen God. He is not teaching that salvation is earned through good works. Throughout his writings, John consistently teaches that salvation comes through faith in Jesus Christ.
Instead, John is describing the evidence of genuine faith. Just as healthy fruit reveals a healthy tree, a transformed life reveals a transformed heart. Good works are not the root of salvation—they are the fruit of salvation.
This truth brings balance to the Christian life. We are saved entirely by God’s grace, yet His grace never leaves us unchanged. Those who belong to Christ increasingly reflect His character through lives marked by love, obedience, humility, and faithfulness.
Application: Rather than asking only whether you have believed the gospel, ask whether the gospel is continuing to transform your attitudes, priorities, and relationships.
3) A Godly Reputation Is Earned Over Time
John introduces Demetrius with remarkable confidence. He says that everyone speaks well of him, that the truth itself testifies in his favor, and that John personally affirms his character. This threefold testimony paints a picture of a man whose private life matched his public profession.
Reputation is not built in a single moment. It is formed through thousands of ordinary decisions made over months and years. Faithfulness in unseen moments eventually becomes visible to others.
In a culture that often values visibility over integrity, Demetrius reminds us that God is more concerned with character than popularity. Long after titles, accomplishments, and public recognition fade away, a life marked by faithfulness continues to influence others.
Application: Build the kind of character that remains the same whether people are watching or not. Integrity developed in private becomes credibility in public.
4) Christianity Was Never Meant to Be Lived Alone
John’s closing remarks may seem like simple travel plans, but they reveal something important about the Christian life. Although letters were valuable, John longed to encourage Gaius face to face. Personal fellowship could accomplish something that written words alone could not.
From the very beginning, the church gathered together for worship, teaching, prayer, fellowship, and encouragement. Christianity has always been deeply relational because God uses His people to strengthen one another’s faith.
Technology has made communication easier than ever, but it has not replaced the need for genuine Christian relationships. Conversations, shared meals, prayer, worship, and discipleship continue to be essential means through which God helps His people grow.
Application: Prioritize face-to-face relationships with other believers. Join a small group, disciple someone, invite another family into your home, or simply spend intentional time encouraging fellow Christians.
5) The Goal Is to Become an Example Worth Following
Third John ends with a challenge that extends far beyond Demetrius himself. Every believer is leaving behind an example. The question is not whether people are watching our lives—they are. The question is what they are learning from us.
Gaius showed us what it looks like to walk in the truth. Diotrephes warned us about the dangers of pride. Demetrius demonstrates the beauty of faithful perseverance. Together, these three men remind us that our daily choices shape both our own walk with Christ and the influence we have on others.
Ultimately, Christian maturity is not measured by how much we know but by how faithfully we help others follow Jesus. The greatest legacy a believer can leave is not fame or success but a life that consistently points people to Christ.
Application: Live today with tomorrow’s legacy in mind. Ask God to help you become the kind of person whose faith encourages others to trust and follow Jesus more faithfully.
Deep Dive Summary
- Every believer is both following examples and setting an example for others.
- Good works are the evidence of a transformed life, not the means of earning salvation.
- Godly character is developed through years of faithful obedience.
- Christian growth flourishes through authentic relationships and biblical community.
- The greatest legacy we can leave is a life that faithfully points others to Jesus Christ.
Christ Connection
John closes his letter by directing our attention toward a life worth imitating. While Demetrius provides a faithful example, he is not the ultimate example. Like every faithful believer, his life points beyond himself to Jesus Christ.
Throughout the Gospels, Jesus demonstrated perfect goodness. Everything He said, every miracle He performed, every relationship He cultivated, and every act of compassion reflected the character of His Father. Unlike Diotrephes, who sought first place, Jesus humbled Himself in perfect obedience. Unlike every imperfect believer, Jesus never failed to perfectly love God or His neighbor. He alone lived a life completely worthy of imitation.
This helps us understand John’s command: “Do not imitate what is evil, but what is good.” Ultimately, believers are not simply called to imitate good people—they are called to imitate Christ. Godly men and women like Gaius and Demetrius are valuable examples because, to the degree that they faithfully follow Jesus, they help us see what Christlike living looks like in everyday life.
Jesus also modeled the kind of relationships John describes in this letter. He invested personally in His disciples, teaching them not only through sermons but by walking with them, eating with them, praying with them, correcting them, and preparing them to continue His mission after His resurrection. Christianity has always been more than learning information; it is learning to follow Jesus alongside other believers.
Before returning to heaven, Jesus commissioned His followers to make disciples of all nations (Matthew 28:18–20). That mission continues as mature believers invest in younger believers, parents disciple their children, pastors shepherd congregations, and Christians encourage one another to remain faithful. The gospel spreads from one generation to the next through lives that consistently reflect the character of Christ.
Because Jesus died for our sins and rose again, we are no longer defined by our failures or left to imitate the values of the world. Through the Holy Spirit, God is transforming His people into the likeness of His Son. Day by day, He is shaping us into men and women whose lives display His truth, His love, His humility, and His faithfulness.
That means the goal of the Christian life is not simply to become more knowledgeable but more Christlike. As we follow Jesus, we become examples that encourage others to follow Him as well. The greatest compliment a believer can receive is not, “You are impressive,” but, “Your life helps me see Jesus more clearly.”
Bottom Line (3 John 11–15)
God calls every believer to reject evil, imitate what is good, and become an example that points others to Jesus Christ. As we cultivate Christlike character, invest in authentic Christian relationships, and faithfully encourage one another, God uses our lives to strengthen His church and reproduce faithful disciples for generations to come.
