Now the Lord of peace. This prayer seems to be connected with the preceding sentence, with the view of recommending endeavors after concord and mildness. He had forbidden them to treat even the contumacious [1] as enemies, but rather with a view to their being brought back to a sound mind [2] by brotherly admonitions. He could appropriately, after this, subjoin an injunction as to the cultivation of peace; but as this is a work that is truly Divine, he betakes himself to prayer, which, nevertheless, has also the force of a precept. At the same time, he may also have another thing in view -- that God may restrain unruly persons, [3] that they may not disturb the peace of the Church.

Now the Lord of peace - The Lord who alone can impart peace; see the Romans 15:33 note; 1-Corinthians 14:33 note; Hebrews 13:20 note; John 14:27 note.

The Lord of peace - Jesus Christ, who is called our peace, Ephesians 2:14; and The Prince of peace, Isaiah 9:6. May he give you peace, for he is the Fountain and Dispenser of it.
Always - Both in your own consciences, and among yourselves.
By all means - Παντι τροπῳ· By all means, methods, occasions, instruments, and occurrences; peace or prosperity in every form and shape.
Instead of εν παντι τροπῳ, in every way, etc., εν παντι τοπῳ, in every place, is the reading of A*D*FG, some others; with the Vulgate and Itala. Chrysostom, Ambrosiaster, Augustine, and others, have the same reading: May God grant you prosperity always, and everywhere.
The Lord be with you all - This is agreeable to the promise of our Lord: Lo, I am with you alway, even unto the end of the world; Matthew 28:20. May the Lord, who has promised to be always with his true disciples, be with you! Christians are the temple of God, and the temple of God has the Divine presence in it. May you ever continue to be his Church, that the Lord God may dwell among you!

Now the Lord of peace himself,.... The Prince of peace, who is peaceable himself, and the author of peace in all his churches, and who requires peace, calls for it, and encourages it:
give you peace always by all means; both a conscience peace, through the blood, righteousness, and sacrifice of Christ, and faith in them, which passes all understanding, and which, when he gives, none can take away; and a church peace, being freed from all such disorderly persons and their abettors, the disturbers of it: and indeed, the way to have true peace and prosperity in churches is to keep up the discipline of God's house. The apostle prays for it in faith, upon an observance of the rules he had given; he prays for constant and perpetual peace, which is greatly to be desired; and that it might be had by all means, and in every way through praying, preaching, administering the ordinances, laying on censures, when necessary, and Christian conversation. Some copies, and the Vulgate Latin version, read "in every place"; as well as at Thessalonica.
The Lord be with you all; by his presence, to comfort and refresh; by his power, to keep and preserve; by his grace, to assist; and by his Spirit, to counsel, advise, and direct.

The apostle prays for the Thessalonians. And let us desire the same blessings for ourselves and our friends. Peace with God. This peace is desired for them always, or in every thing. Peace by all means; in every way; that, as they enjoyed the means of grace, they might use all methods to secure peace. We need nothing more to make us safe and happy, nor can we desire any thing better for ourselves and our friends, than to have God's gracious presence with us and them. No matter where we are, if God be with us; nor who is absent, if God be present. It is through the grace of our Lord Jesus Christ, that we hope to have peace with God, and to enjoy the presence of God. This grace is all in all to make us happy; though we wish ever so much to others, there remains enough for ourselves.

Lord of peace--Jesus Christ. The same title is given to Him as to the Father, "the GOD of peace" (Romans 15:33; Romans 16:20; 2-Corinthians 13:11). An appropriate title in the prayer here, where the harmony of the Christian community was liable to interruption from the "disorderly." The Greek article requires the translation, "Give you the peace" which it is "His to give." "Peace" outward and inward, here and hereafter (Romans 14:17).
always--unbroken, not changing with outward circumstances.
by all means--Greek, "in every way." Most of the oldest manuscripts read, "in every place"; thus he prays for their peace in all times ("always") and places.
Lord be with you all--May He bless you not only with peace, but also with His presence (Matthew 28:20). Even the disorderly brethren (compare 2-Thessalonians 3:15, "a brother") are included in this prayer.

The Lord of peace - Christ. Give you peace by all means - In every way and manner.
