Verse 6.— Which have borne witness. Persons upon whom these Christian favors had been bestowed by Gaius, the recipients of his Christian charity, had given the apostle information concerning it. It should, therefore, be no surprise to Gaius that the writer should speak of the matter in this epistle. These informants also testified before the church about this exhibition of love which Gaius had for the cause of Christ. I take it, that many of these recipients of the hospitality of Gaius had been out upon missions of one kind or another connected with the church— possibly upon evangelizing tours— and while the apostle not only rejoices at and commends Gaius for receiving these into his home, he also adds the additional method of helping the proclamation of the word in this, by aiding the proclaimers in going from place to place. These journeys are attended with labor and more or less expense. Gaius may aid in lessening the one or the other by his con­tributions. In this, should you thus act, you will do well. After a godly sort. This would be well pleasing to God. It is as God would have you do. This will meet the approbation of the Master. The meaning is this: in addition to your hospitality to brethren and strangers, if you add such additional help as you can to those who are away on missions for or on behalf of the church, thus making their labor or expenses lighter on their journeys, you will also be performing acts well pleasing to God.
