Gaius the faithful, Diotrephes the proud
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.
3 John 1:113 John is a private letter to Gaius, a faithful Christian known for his hospitality. John commends Gaius for receiving traveling preachers and supporting their ministry. Then he contrasts Gaius with Diotrephes, a church leader who loves to have the preeminence, refuses to receive John's messengers, and casts out those who do. Finally, John commends Demetrius, who has a good report. The letter is a study in contrasts: faithful hospitality vs. prideful power, humble service vs. domineering control.
The structure is simple: greeting and prayer for Gaius (vv. 1-4), commendation of Gaius' hospitality (vv. 5-8), condemnation of Diotrephes' pride (vv. 9-10), exhortation to follow good not evil (v. 11), commendation of Demetrius (v. 12), and closing (vv. 13-14). The letter addresses a problem that still plagues the church: leaders who love power more than people, who refuse accountability, and who bully dissenters. Diotrephes is the prototype of every controlling pastor, every spiritual abuser, every leader who demands submission to himself rather than to Christ.
The theological application is clear: imitate what is good. Gaius shows us what faithful Christianity looks like — hospitality, generosity, support for truth-tellers. Diotrephes shows us what pride looks like — refusal to listen, rejection of authority, expulsion of dissenters. The test: he that does good is of God; he that does evil has not seen God. Actions reveal the heart. Follow Gaius, not Diotrephes.

John commends Gaius for receiving traveling preachers and sending them on their way. 'For they went forth for his name's sake, taking nothing of the Gentiles. We therefore ought to receive such, that we might be fellowhelpers to the truth.' The traveling preachers refused to take money from unbelievers to avoid compromising the Gospel. Believers like Gaius supported them. By doing so, Gaius became a fellow helper to the truth. You do not have to be a preacher to serve the truth. You can support those who preach. Hospitality, generosity, and encouragement are ministries. They make you a partner in the work.
John describes Diotrephes: '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.' Diotrephes is the archetype of the controlling church leader. He loves power. He rejects accountability. He slanders those who challenge him. He forbids hospitality and expels dissenters. This is spiritual abuse. And John will confront it. Leaders who act like Diotrephes are not of God. They are dangers to the flock.
'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.' This is the test. Actions reveal the heart. Gaius does good; he is of God. Diotrephes does evil; he has not seen God. The command is simple: imitate what is good, not what is evil. Do not follow controlling leaders. Do not imitate prideful pastors. Follow those who walk in truth, show hospitality, and serve humbly. The standard is not success or charisma. It is godliness.
John opens with a prayer: 'Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth.' Then he adds: 'I have no greater joy than to hear that my children walk in truth.' John cares about Gaius' physical health, but his greater concern is spiritual health. The prosperity gospel inverts this. It makes physical prosperity the priority and spiritual health secondary. John's priority is the opposite. He rejoices when his spiritual children walk in truth. That is his greatest joy. Physical health is a blessing, but spiritual health is essential.
