Verse-by-Verse Commentary
The Book of 3 John
Chapter 1: Imitate What Is Good
John's shortest letter by word count is a study in contrasts. Gaius is a faithful believer, walking in the truth and generous in hospitality to traveling ministers. Diotrephes is the opposite, a man who loves to have preeminence, rejects apostolic authority, and pushes others out of the church. Between them, John states a simple, searching principle: do not imitate what is evil, but what is good. Third John shows us godliness and pride side by side, and calls us to choose whom we will resemble.

Setting the Stage
A Tale of Two Men
Third John is a brief, personal letter contrasting the faithful, hospitable Gaius with the proud, domineering Diotrephes, and commending the well-attested Demetrius.
John the Apostle
John, again calling himself "the Elder," writes to his friend Gaius, whom he loved in the truth, late in the first century.
Hospitality and Its Enemy
Traveling ministers depended on the hospitality of local believers. Gaius gave it faithfully; Diotrephes refused it and expelled those who offered it. John writes to commend the one and confront the other.
Follow the Good
Character is revealed in how we treat God's servants and whether we seek to serve or to be preeminent. John calls us to imitate the good and reject the evil.
No Greater Joy (3 John 2-4)
John expresses his deepest joy: to see his spiritual children living in the truth.
My Children Walk in Truth
"The elder unto the wellbeloved Gaius, whom I love in the truth. Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth."
Greek Study
John's warm greeting has become a famous prayer: "I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth." The word "prosper" is euodoō — literally "to have a good journey," to be led along a good road. John prays that Gaius's outward life — body and circumstances — would fare as well as his flourishing soul (psychē). The measure he sets is the health of the inner man; he wishes the body well "even as" the soul is already well.
Explanation
The prayer quietly reverses how most people measure blessing. John assumes the soul is thriving and wishes the body might catch up — "even as thy soul prospereth." For many it would be the opposite: a healthy body and a starved soul. And John names his deepest joy: "I have no greater joy than to hear that my children walk in truth." The old apostle's happiness is not in his own comfort but in the faithfulness of his spiritual children. What gladdens a true shepherd most is not success but the steady, truthful walk of those he has led to Christ.
Gospel Focus
John opens by wishing that Gaius may "prosper and be in health, even as thy soul prospereth" (verse 2), a prayer that assumes the soul's prosperity is the truest measure of well-being. Then he names his greatest joy: "that my children walk in truth." For a spiritual father, no success or reward compares to seeing those he has led to Christ living faithfully. This is the heart of every true minister and parent in the faith: our deepest joy is not in our own achievements but in the faithfulness of those we love. It also reminds us what matters most, not merely that people profess faith, but that they "walk" in the truth, living it out day by day. To walk in truth is to bring joy to the heart of God and of those who labor for our souls.
Diotrephes (3 John 9-10)
John confronts a man whose pride had made him an obstacle in the church.
Who Loves to Have Preeminence
"For I rejoiced greatly, when the brethren came and testified of the truth that is in thee, even as thou walkest in the truth."
Greek Study
John names a troubler by name: Diotrephes, "who loveth to have the preeminence" — philoprōteuō, literally "loving to be first." This one Greek word diagnoses the whole problem: a craving to be number one. Out of that pride Diotrephes rejects the apostle's authority, spreads "malicious words" against him, refuses to receive the traveling brethren, and even casts out of the church those who would. Love of preeminence is a poison that turns a leader into a tyrant.
Explanation
Diotrephes is the tragic opposite of the humble Gaius. Where Gaius quietly served the truth and welcomed strangers, Diotrephes grasps for control — silencing the apostle, slandering him, barring the door to visiting believers, and excommunicating any who disobey him. His sin is not heresy but ego: he "loveth to have the preeminence." John's brief portrait is a lasting warning that the deadliest danger to a church is sometimes not false doctrine but a leader in love with his own importance.
Gospel Focus
Diotrephes is a warning in a single verse. His root problem was that he "loves to have the preeminence", he wanted to be first, to dominate, to be seen and served. From that pride flowed the rest: he rejected apostolic authority, spoke against John "with malicious words," refused to welcome the traveling brethren, and even put out of the church those who did (verse 10). Pride in leadership is destructive; the desire to be preeminent is the exact opposite of Christ, who "came not to be ministered unto, but to minister" (Matthew 20:28). Jesus taught, "whosoever will be great among you, let him be your minister" (Matthew 20:26). Diotrephes wanted the first place that belongs to Christ alone, "that in all things he might have the preeminence" (Colossians 1:18). Beware the love of preeminence; true greatness in God's kingdom is found in serving, not in being first.
Imitate What Is Good (3 John 11)
John draws the lesson from the two examples into a single principle for every believer.
He Who Does Good Is of God
"For I rejoiced greatly, when the brethren came and testified of the truth that is in thee, even as thou walkest in the truth. I have no greater joy than to hear that my children walk in truth. Beloved, thou doest faithfully whatsoever thou doest to the brethren, and to strangers; Which have borne witness of thy charity before the church: whom if thou bring forward on their journey after a godly sort, thou shalt do well: Because that for his name's sake they went forth, taking nothing of the Gentiles. We therefore ought to receive such, that we might be fellowhelpers to the truth. I wrote unto the church: but Diotrephes, who loveth to have the preeminence among them, receiveth us not. Wherefore, if I come, I will remember his deeds which he doeth, prating against us with malicious words: and not content therewith, neither doth he himself receive the brethren, and forbiddeth them that would, and casteth them out of the church. Beloved, follow not that which is evil, but that which is good. He that doeth good is of God: but he that doeth evil hath not seen God. Demetrius hath good report of all men, and of the truth itself: yea, and we also bear record; and ye know that our record is true. I had many things to write, but I will not with ink and pen write unto thee: But I trust I shall shortly see thee, and we shall speak face to face. Peace be to thee. Our friends salute thee. Greet the friends by name."
Greek Study
John's summary charge turns on a single verb: "follow not that which is evil, but that which is good" — mimeomai, to imitate, the root of our word "mimic." We become like what we copy. And the test is plain: "he that doeth good is of God: but he that doeth evil hath not seen God." Character reveals origin. Set between the bad example of Diotrephes and the good example of Demetrius, Gaius is told simply to imitate the good, for what a person habitually copies shows whose he truly is.
Explanation
The little letter's moral is compact: choose your models well. Having just described the domineering Diotrephes and about to commend the well-reported Demetrius, John tells Gaius to "follow not that which is evil, but that which is good." We are all imitators of someone, and the direction of a life shows in what it copies. The one who habitually does good gives evidence that he is "of God"; the one who does evil shows he "hath not seen God." Discipleship is, in large part, learning to imitate the right examples of Christ-shaped goodness.
Gospel Focus
Having shown the good example of Gaius and the evil example of Diotrephes, John gives the takeaway: "do not imitate what is evil, but what is good." We become like what we imitate, so we must choose our models carefully. And John gives a searching test: "He who does good is of God, but he who does evil has not seen God." This does not teach that we earn salvation by good works, but that a life is evidence of its source; those who truly know God bear the fruit of His character, while a life given over to evil shows a heart that has not truly known Him. The way we live reveals whose we are. So imitate the Gaiuses, not the Diotrepheses; follow those who serve, walk in truth, and do good, for in doing good we show that we belong to the God who is good.
3 John in Review
3 John, a short letter of fourteen verses, is a study in contrasts. John rejoices that his beloved friend Gaius walks in the truth and shows faithful hospitality to traveling ministers, declaring he has no greater joy than to see his children walk in truth. Against this he sets Diotrephes, a man who "loves to have the preeminence," who rejects apostolic authority, slanders, and expels the hospitable from the church. From these two examples John draws his principle: do not imitate what is evil, but what is good, for the way we live reveals whether we are truly of God.
For the Apostolic reader, this brief letter is intensely practical. The greatest joy in ministry is seeing others walk in truth. The love of preeminence is a deadly danger in the church, the very opposite of the servant heart of Christ. And our lives reveal their source: those who know God do good, while a life of evil betrays a heart that has not seen Him. We become like what we imitate, so let us follow the Gaiuses and not the Diotrepheses, seeking to serve rather than to be first, and doing good because we belong to the God who is good.
- The deepest joy in the faith is to see those we love walking in truth.
- The love of preeminence is destructive and opposite to the servant heart of Christ (Matthew 20:26-28).
- We become like what we imitate; choose good examples, not evil ones.
- Our lives reveal their source: those who do good show they are of God.
