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:

(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 upon 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 Saviour. 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.

To hear that my children - From this it has been inferred that Caius was one of St. John's converts, and consequently not the Corinthian Caius, who was converted, most probably, by St. Paul. But the apostle might use the term children here as implying those who were immediately under his pastoral care, and, being an old man, he had a right to use such terms in addressing his juniors both in age and grace; and there is much both of propriety and dignity in the appellation coming from such a person.

I have no greater joy,.... Nothing that causes greater joy. The Vulgate Latin version reads "grace" or "thanks"; and then the sense is, that he had nothing to be more thankful for:

than to hear that my children walk in truth; meaning his spiritual children, those whose conversion he had been the instrument of; and among these it seems Gaius was one.

Joy (χαρὰν)

The texts vary; some reading χάριν grace or favor from God, on which see 2 John 1:3. Note the Greek order: greater joy than this have Inot.

My children (τὰ ἐμὰ τέκνα)

Lit., mine own children.

Walk (περιπατοῦντα)

Rev., rightly, walking. The participle expresses something habitual.

I have no greater joy than {a} to hear that my children walk in truth.

(a) Than these joys.

1:4 I have no greater joy. That which gave him the greatest joy was to know that the saints walked in the truth.

My children. The aged John was wont to call the saints his children. See 1Jo 2:1,12,18,28 4:04 5:21.

1:4 I have no greater joy than this - Such is the spirit of every true Christian pastor. To hear that my children walk in the truth - Caius probably was converted by St. Paul. Therefore when St. John speaks of him. with other believers, as his children, it may be considered as the tender style of paternal love, whoever were the instruments of their conversion. And his using this appellation, when writing under the character of the elder, has its peculiar beauty.

4. my children-members of the Church: confirming the view that the "elect lady" is a Church.

1:1-8 Those who are beloved of Christ, will love the brethren for his sake. Soul prosperity is the greatest blessing on this side heaven. Grace and health are rich companions. Grace will employ health. A rich soul may be lodged in a weak body; and grace must then be exercised in submitting to such a dispensation. But we may wish and pray that those who have prosperous souls, may have healthful bodies; that their grace may shine where there is still more room for activity. How many professors there are, about whom the apostle's words must be reversed, and we must earnestly wish and pray that their souls might prosper, as their health and circumstances do! True faith will work by love. A good report is due from those who receive good; they could not but testify to the church, what they found and felt. Good men will rejoice in the soul prosperity of others; and they are glad to hear of the grace and goodness of others. And as it is a joy to good parents, it will be a joy to good ministers, to see their people adorn their profession. Gaius overlooked petty differences among serious Christians, and freely helped all who bore the image, and did the work of Christ. He was upright in what he did, as a faithful servant. Faithful souls can hear their own praises without being puffed up; the commendation of what is good in them, lays them at the foot of the cross of Christ. Christians should consider not only what they must do, but what they may do; and should do even the common actions of life, and of good-will, after a godly sort, serving God therein, and designing his glory. Those who freely make known Christ's gospel, should be helped by others to whom God gives the means. Those who cannot themselves proclaim it, may yet receive, help, and countenance those who do so.
