(17) Comfort your hearts . . .--"Comfort," in reference to the "unending comfort" of 2Thessalonians 2:16; and "stablish," in reference to the "good hope in grace." The "heart" needs comfort as the seat of emotions. "In every good word and work" (it should be, work and word) means in the maintenance of every good doctrine (as opposed to the false teaching which had got abroad about the Advent, and to the lies of the Apostasy), and in the performance of every good practice (as opposed to the lawlessness of the Apostasy, and to the disorderly conduct of which the next chapter treats: for here, as in 1Thessalonians 3:13, the prayer forms an introduction of the next subject). The singular number of the verbs "comfort" and "stablish" (which, of course, does not appear in the English), may perhaps be explained as in 1Thessalonians 3:12, where see Note, though it is not necessary so to understand it, inasmuch as the intervening relative (in the Greek, participial) clauses have turned the whole attention to the Father, who may be considered exclusively as the grammatical subject of the verbs. It would, however, have been painful to orthodox ears; however justifiable doctrinally, to have used a plural verb. It is by these little incidental touches, still more than by express doctrinal statements, that we learn what was the real belief of the Apostles concerning the Divinity of Christ; and we may say the same with regard to many other great doctrines.

Verse 17. - Comfort your hearts, and stablish you; or, according to the best manuscripts, stablish them. namely, your hearts. These verbs are in the singular, but their nominative is our Lord Jesus Christ and God our Father, thus implying the unity between these Divine Persons. In every good word and work.

2:16,17 We may and should direct our prayers, not only to God the Father, through our Lord Jesus Christ, but also to our Lord Jesus Christ himself. And we should pray in his name unto God, not only as his Father, but as our Father in and through him. The love of God in Christ Jesus, is the spring and fountain of all the good we have or hope for. There is good reason for strong consolations, because the saints have good hope through grace. The free grace and mercy of God are what they hope for, and what their hopes are founded on, and not any worth or merit of their own. The more pleasure we take in the word, and works, and ways of God, the more likely we shall be to persevere therein. But, if we are wavering in faith, and of a doubtful mind, halting and faltering in our duty, no wonder that we are strangers to the joys of religion.Comfort your hearts,.... That is, apply the comfort given, and cause it to be received, which unbelief is apt to refuse; and increase it, by shedding abroad the love of Christ, and of the Father; by the discoveries of pardoning grace; by the application of Gospel promises; by the word and ordinances, which are breasts of consolation; and by indulging with the gracious presence, and comfortable communion of Father, Son, and Spirit. The Arabic version reads, "comfort your hearts by his grace", joining the last clause of the preceding verse to this. This petition stands opposed to a being troubled and distressed about the sudden coming of Christ, as the following one does to a being shaken in mind on that account, 2 Thessalonians 2:2.

And stablish you in every good word and work; that is, in every good word of God, or truth of the Gospel, which contains good tidings of good things, so as not to waver about them, or stagger in them, or to depart from them; in practice of every duty, so as to be steadfast, and immoveable, and always abounding therein; good words and good works, principles and practices, should go together, and the saints stand in need of stability in both. For though, as to their state and condition, they are established in the love of God, in the covenant of grace, in the arms of Christ, and in him the foundation, so as they can never be removed; yet they are often very unstable, not only in their frames, and in the exercise of grace, but in their attachment and adherence to the Gospel and interest of Christ, and in the discharge of duty.
