3 John 3-6

Verse 3. For I rejoiced greatly when the brethren came. Who these were is not certainly known. They may have been members of the same church with Gaius, who, for some reason, had visited the writer of this epistle; or they may have been the "brethren" who had gone from him with a letter of commendation to the church, (1Jn 1:9,) and had been rejected by the church through the influence of Diotrephes, and who, after having been hospitably entertained by Gaius, had again returned to the writer of this epistle. In that case, they would of course bear honourable testimony to the kindness which they had received from Gaius, and to his Christian character.

And testified of the truth that is in thee. That you adhere steadfastly to the truth, notwithstanding the fact that errors abound, and that there are many false teachers in the world.

Even as thou walkest in the truth. Livest in accordance with the truth. The writer had made the same remark of the children of Cyria, to whom the second epistle was directed. 2Jn 1:4.

(a) "walkest" 2Jn 1:4
Verse 4. I have no greater joy than to hear that my children walk in truth. That they adhere steadfastly to the truth, and that they live in accordance with it. This is such language as would be used by an aged apostle when speaking of those who had been converted by his instrumentality, and who looked up to him as a father; and we may, therefore, infer that Gaius had been converted under the ministry of John, and that he was probably a much younger man than he was. John, the aged apostle, says that he had no higher happiness than to learn, respecting those who regarded him as their spiritual father, that they were steadfast in their adherence to the doctrines of religion. The same thing may be said now

(a.) of all the ministers of the gospel, that their highest comfort is found in the fact that those to whom they minister, whether still under their care or removed from them, persevere in a steadfast attachment to the true doctrines of religion, and live accordingly; and

(b.) of all Christian parents respecting their own children. The highest joy that a Christian parent can have is to know that his children, whether at home or abroad, adhere to the truths of religion, and live in accordance with the requirements of the gospel of Christ. If a child wished to confer the highest possible happiness on his parents when with them, it would be by becoming a decided Christian; if, when abroad, in foreign lands or his own, he wished to convey intelligence to them that would most thrill their hearts with joy, it would be to announce to them that he had given his heart to God. There is no joy in a family like that when children are converted; there is no news that comes from abroad that diffuses so much happiness through the domestic circle as the intelligence that a child is truly converted to the Saylout. There is nothing that would give more peace to the dying pillow of the Christian parent, than to be able to leave the world with the assurance that his children would always walk in truth.

(b) "joy" Prov 23:24
Verse 5. Beloved, thou doest faithfully. In the previous verses the writer had commended Gaius for his attachment to truth, and his general correctness in his Christian life. He now speaks more particularly of his acts of generous hospitality, and says that he had fully, in that respect, done his duty as a Christian.

Whatsoever thou doest. In all your intercourse with them, and in all your conduct towards them. The particular thing which led to this remark was his hospitality; but the testimony respecting his general conduct had been such as to justify this commendation.

To the brethren. Probably to Christians who were well known to him--perhaps referring to Christians in his own church.

And to strangers. Such as had gone to the church of which he was a member with a letter of commendation from John. Rom 12:13, and Heb 13:2.

(c) "faithfully" 1Pet 4:10
Verse 6. Which have borne witness of thy charity before the church. It would seem that they had returned to John, and borne honourab1e testimony to the love manifested to them by Gaius. Before what church they had borne this testimony is unknown. Perhaps it was the church in Ephesus.

Whom if thou bring forward on their journey, ουςπροπεμψας. "Whom bringing forward, or having brought forward." The word refers to aid rendered them in their journey, in facilitating their travels, either by personally accompanying them, by furnishing them the means of prosecuting their journey, or by hospitably entertaining them. Probably Gains aided them in every way in which it was practicable. It has been made a question whether this refers to the fact that he had thus aided them in some visit which they had made to the church where Gaius was, or to a visit which they purposed to make. The Greek would seem to favour the latter construction, and yet it would appear from the epistle, that the "brethren and strangers" actually had been with him; that they had been rejected by the church through the influence of Diotrephes, and had been thrown upon the hospitality of Gaius, and that they had returned, and had borne honourable testimony to his hospitality. These views can be reconciled by supposing, as Loicke does, that having been once on their travels, and having shared the hospitality of Gaius, they were purposing to visit that region again, and that John, praising him for his former hospitality, commends them again to him, stating the reason (3Jn 1:9,10) why he did not, in accordance with the usual custom, recommend them to the care of the church. They had now gone out (3Jn 1:7) on the same errand on which they had formerly gone, and they had now equal claims to the hospitality of the friends of religion.

After a godly sort. Margin, as in Greek, worthy of God. The meaning is, As becomes those who serve God; or as becomes those who are professors of his religion.

Thou shalt do well. You will do that which religion requires in these circumstances.

(d) "forward on their journey" Acts 15:3 (3) "after a godly sort" "worthy of God"
