2 Thessalonians 1:3-4

3We ought always and indeed are morally obligated [as those in debt] to give thanks to God for you, brothers and sisters, as is fitting, because your faith is growing ever greater, and the [unselfish] love of each one of you toward one another is continually increasing.

4Therefore, we speak of you with pride among the churches of God for your steadfastness [your unflinching endurance, and patience] and your firm faith in the midst of all the persecution and [crushing] distress which you endure.
