John Chrysostom

"Finally, brethren, pray for us, that the word of the Lord may run and be glorified, even as also it is with you." He indeed had prayed for them, that they might be stablished; and now he asks of them, entreating them to pray for him, not that he may not incur danger, for to this he was appointed, but that "the word of the Lord may run and be glorified, even as also it is with you." And the request is accompanied with commendation. "Even as also it is with you."

Homily on 2 Thessalonians 4 ↗

Theophylact of Ohrid

He himself had previously prayed for them, that they might be established in the faith; now he asks them to pray for him, not asking that he not be subjected to dangers (for he had devoted himself to this), but that "the word of the Lord may spread and be glorified." Here the request is joined with praise: "as," he says, "among you," so that all might likewise submit to it, as you did. Thus the apostle asks nothing for himself personally, but everything for God's sake.

Commentary on 2 Thessalonians ↗

Clement of Alexandria

"Many rod-bearers there are, but few Bacchi," according to Plato. "For many are called, but few chosen." "Knowledge is not in all," says the apostle.

The Stromata Book 5 ↗

Augustine of Hippo

With this in mind, dearly beloved, let us always look forward with longing toward our everlasting joy. Let us always pray for fortitude in our temporal labors and trials. Let us offer prayers for one another. Let my prayers be offered for you, and yours for me. And, brothers, do not think that you need my prayers, but that I have no need of yours. We have mutual need of one another's prayers, for those reciprocal prayers are enkindled by charity and—like a sacrifice offered on the altar of piety—are fragrant and pleasing to the Lord. …

Sermons 13.10 ↗

Ambrose of Milan

Indeed, there is good wisdom, but sweet mercy. Few attain the former, while the latter reaches everyone. Because of this, he says, souls renewed by the spirit love you. Hence, it is also said to the soul: Your youth will be renewed like the eagle's. For he was speaking to the soul, saying: Bless the Lord, O my soul. And therefore it hurries to the Word, and asks to be drawn, lest it be left behind; for the Word of God runs and is not hindered.

On Isaac and the Soul 3.10 ↗

Thomas Aquinas

Above, he instructed them about what will happen in the last days. Here he instructs them about certain things that they particularly needed to do. And first, he sets out his instruction; second, the conclusion of the epistle, at "now may the God of peace himself." And first he advises them about how they should relate to himself; second, he says what he is confident about concerning them, at "but God is faithful"; third, how they should relate to others who walk in a disorderly manner, at "and we charge you." Concerning the first, …
