3 John 1:8

‘We therefore ought to welcome such, that we may be fellow-workers for the truth.'

It was right that these travelling preachers should be welcomed and given hospitality, because of Whose they were, and by doing so Gaius had a part in their ministry. He was a fellow-worker with them in the truth. All may not be able to preach, but all can have a part in the ministry of such people by their continual support. It was the widow who gave her pittance who was especially honoured by God, not the wealthy donors in the Temple, for she gave of her all (Mark 12:41). One cup of cold water rightly given can quench the thirst of Heaven.
