[:en]John wrote to commend Gaius, who was taking care of traveling teachers and missionaries. He warned against people like Diotrephes who refused to listen to spiritual leaders in authority. Instead, he was gossiping maliciously about them and refused to welcome them.
Gaius was a friend of John and a faithful leader in the church. John was concerned for Gaius physical and spiritual well-being, so he prayed for his health and soul. John’s greatest joy was to hear that Gaius was faithful in the truth as he continued to walk in the truth.
John personified truth as a witness to Demetrius character and testimony. He urged church members to show hospitality to those who teach the truth. Sharing hospitality means prayer, encouragement, a gift, financial support or an open home.[:]
