I.John receives a good report of Gaius's faith and charity from the brethren. Gaius’s love for the brethren and hospitality to strangers proves his sincerity in the faith. II. Gaius is commended for his hospitality, a virtue extended to strangers and those of different churches. III. John expresses great joy in hearing of Gaius's walk in truth. This reflects the joy of ministers when they see their followers living out their faith. IV. John advises Gaius to continue supporting the brethren by aiding them on their journeys in a godly manner, reflecting Christian generosity. V. The brethren went forth preaching for God's sake, taking nothing from the Gentiles. John emphasizes the need for the church to support such ministers, as they help propagate the truth.

Which have borne witness of thy charity - Of thy love and benevolence.

Before the Church - The believers at Ephesus; for to this Church the apostle seems to refer.

Whom if thou bring forward - If thou continue to assist such, as thou hast done, thou shalt do well.

The brethren of whom St. John speaks might have been apostles; the strangers, assistants to these apostles, as John Mark was to Barnabas. Both were itinerant evangelists.

After a godly sort - Αξιως του Θεου· Worthy of God; and in such a way as he can approve. Let all Churches, all congregations of Christians, from whom their ministers and preachers can claim nothing by law, and for whom the state makes no provision, lay this to heart; let them ask themselves, Do we deal with these in a manner worthy of God, and worthy of the profession we make? Do we suffer them to lack the bread that perisheth, while they minister to us with no sparing hand the bread of life? Let a certain class of religious people, who will find themselves out when they read this note, consider whether, when their preachers have ministered to them their certain or stated time, and are called to go and serve other Churches, they send them forth in a manner worthy of God, making a reasonable provision for the journey which they are obliged to take. In the itinerant ministry of the apostles it appears that each Church bore the expenses of the apostle to the next Church or district to which he was going to preach the word of life. So it should be still in the mission and itinerant ministry.

Which have borne witness of thy charity before the church,.... At Ephesus, where John was; these brethren and strangers coming thither, and being greatly affected with Gaius's kindness and liberality to them, could not forbear speaking of it to his praise, in the presence of the members of the church, as well as acquainted the Apostle John with it; the Syriac version reads, "before the whole church"; they bore testimony of his liberality in a very public manner And this the apostle mentions to encourage Gaius to go on, and continue in his kindness to the same persons, since they retained such a grateful sense of past favours; and whereas they were now returning back, he desires that he would give them some further assistance:

whom if thou bring forward on their journey; the word here used signifies, to send on before, as in Act 15:3, and is used by the Septuagint in the same sense as here, and in the above places, in Gen 18:16; where it is said, that "Abraham went with them (the angels) to bring them on in the way", "to send them on", or "send them away"; dismiss them, take his leave of them in a friendly and honourable way. The Targums of Onkelos and Jonathan render it, "to accompany them"; and so this Greek word, which seems to answer to the Hebrew phrase, signifies an honourable accompanying, leading forth, and taking leave of friends; and so the apostle encourages Gaius to behave in like manner to the brethren and strangers; meaning, either by accompanying them in person, or by sending his servants along with them, both to direct them the way, and to secure them from danger, and chiefly by furnishing them with everything necessary for them; see Tit 3:13. And this he would have him do,

after a godly sort; or "worthy of God"; in imitation of God, who is merciful, kind, and beneficent; or as it became him whom God had called by his grace to his kingdom and glory; or as it was fit and proper such servants of God, as those brethren were, should be used; and this would be doing well:

thou shalt do well; what is grateful and well pleasing to God, and beautiful and lovely in the eyes of his people.

borne witness of thy charity before the church--to stimulate others by the good example. The brethren so entertained by Gaius were missionary evangelists (Jo3 1:7); and, probably, in the course of narrating their missionary labors for the edification of the Church where John then was, incidentally mentioned the loving hospitality shown them by Gaius.

bring forward on their journey--"If thou (continue to) forward on their journey" by giving them provisions for the way.

after a godly sort--Greek, "in a manner worthy of God," whose ambassadors they are, and whose servant thou art. He who honors God's missionary servants (Jo3 1:7), honors God.
