2 Thessalonians 1:3-8

We ought always to give thanks to God for you, brothers, as is right, because your faith is growing abundantly, and the love of every one of you for one another is increasing. Therefore we ourselves boast about you in the churches of God for your steadfastness and faith in all your persecutions and in the afflictions that you are enduring. This is evidence of the righteous judgment of God, that you may be considered worthy of the kingdom of God, for which you are also suffering— since indeed God considers it just to repay with affliction those who afflict you, and to grant relief to you who are afflicted as well as to us, when the Lord Jesus is revealed from heaven with his mighty angels in flaming fire, inflicting vengeance on those who do not know God and on those who do not obey the gospel of our Lord Jesus.
