3 John is a personal letter from John to Gaius, commending him for walking in the truth and faithfully supporting fellow believers who were serving the Gospel. Through Gaius, Diotrephes and Demetrius, John presents three contrasting examples of Christian character: humble service, self-centred leadership and faithful witness. The letter reminds us that walking in truth must become visible through how we serve, welcome and treat others. It also warns us against allowing pride, recognition or personal influence to become more important than Christ and His people. Ultimately, 3 John calls us to live faithfully, serve generously, lead humbly and allow our lives to become a credible testimony to the truth we profess.
