John commends Gaius for hospitality toward traveling missionaries and warns against a domineering leader named Diotrephes.
3 John (also 13 verses) is the shortest book in the Bible by word count. It commends Gaius for walking in truth and showing hospitality to traveling missionaries. It warns against Diotrephes, who 'likes to put himself first' and refuses to welcome the brothers.
The letter closes by recommending Demetrius, 'who has a good testimony from everyone.' (12)
Written around the same period as 2 John (80s-90s AD), this letter addresses internal church politics. The conflict between hospitality and control reflected real tensions in the early house-church movement.
The letter models pastoral encouragement of a faithful layperson and gentle confrontation of a self-promoting leader.
3 John shows that hospitality and humility matter. How we treat those who serve the gospel — and whether we put ourselves first — reveals our character.
Be a Gaius: walk in truth, love the brothers, and open your home. Do not be a Diotrephes who loves to be first.
