Albert Barnes on 2 Thessalonians 1:4

So that we ourselves glory in you in the churches of God. That is, we mention your example to other churches, and glory in it, as an evidence of what the gospel is fitted to do. 1Thes 2:19, 1Thes 2:20. Comp. 2Cor 9:2.

For your patience. Your patient endurance of trials.

And faith. Fidelity, or constancy. You have shown unwavering confidence in God in your afflictions.

In all your persecutions and tribulation, that ye endure. 1Thes 2:14; 1Thes 4:13. It would seem from this that the persecutions and trials to which the apostle referred in his first epistle were still continued.

(a) "glory" 2Cor 9:2, 1Thes 2:19,20 (b) "endure" Jas 5:11
