Gaius, the man John was writing to, was a godly man who believed what the apostles taught. He had not embraced false teaching, and his faith was commended by John (3 John 1:3). Now we discover that, like the Lady in 2 John, Gaius had a wonderful ministry of hospitality. The churches were growing fast, partly because they appointed suitable people to be sent out as missionaries to preach the gospel and plant new churches (Acts 13:2-3).
