Matthew Henry Commentary Titus 3:12-15

"When I shall send Artemas unto thee, or Tychicus, give diligence to come unto me to Nicopolis: for there I have determined to winter. Set forward Zenas the lawyer and Apollos on their journey diligently, that nothing be wanting unto them. And let our [people] also learn to maintain good works for necessary uses, that they be not unfruitful. All that are with me salute thee. Salute them that love us in faith. Grace be with you all." — Titus 3:12-15 (ASV)

Christianity is not a fruitless profession; and its followers must be filled with the fruits of righteousness, which are by Jesus Christ, to the glory and praise of God. They must be doing good, as well as keeping away from evil. Let “ours” pursue some honest labour and employment, to provide for themselves and their families.

Christianity obliges all to seek some honest work and calling, and in that calling to abide with God. The apostle concludes with expressions of kind regard and fervent prayer. Grace be with you all; the love and favour of God, with their fruits and effects, according to need; and the increase and feeling of them more and more in your souls.

This is the apostle's wish and prayer, showing his affection for them and his desire for their good, and it would be a means for them to obtain what was requested and for it to be bestowed upon them. Grace is the chief thing to be wished and prayed for, concerning ourselves or others; it is “all good.”
