Summary
John the elder writes to his beloved friend Gaius, expressing love and joy over Gaius’s faith and good deeds, especially his hospitality toward the brethren and strangers. He commends Gaius for following truth and doing charity, citing the testimonies of those who have seen his faith. The letter then turns to Diotrephes, who rejects the author’s authority, spreads falsehoods, and refuses to receive the brothers, even forbidding others from doing so. John urges the readers to avoid evil and to follow good, declaring that those who do good are from God. He mentions Demetrius as a trustworthy witness. Finally, John signs off with a hopeful note of meeting in person, peace, and greetings from mutual friends.
