What is this book about?
3 John is a brief letter written by the Apostle John, likely drawing from his experiences and teachings. It expresses deep appreciation for Gaius, who is described as walking in the truth, serving the saints, and showing hospitality. The letter strongly condemns Diotrephes, a leader in the church at Ephesus, who was divisive, arrogant, and refused to acknowledge John's apostolic authority or welcome his traveling companions. Through these contrasting examples, John offers practical guidance on how to live faithfully and lovingly as a Christian in the early days of the faith.
