We must always thank God for you, brothers, which is fitting, since your faith is flourishing, and the love of every one of you for one another is increasing.
References for 2 Thessalonians 1:3
Therefore we ourselves boast about you among God's churches-about your endurance and faith in all the persecutions and afflictions you endure.
It is a clear evidence of God's righteous judgment that you will be counted worthy of God's kingdom, for which you also are suffering,
since it is righteous for God to repay with affliction those who afflict you,
and [to reward] with rest you who are afflicted, along with us. [This will take place] at the revelation of the Lord Jesus from heaven with His powerful angels,
taking vengeance with flaming fire on those who don't know God and on those who don't obey the gospel of our Lord Jesus.
These will pay the penalty of everlasting destruction, away from the Lord's presence and from His glorious strength,
in that day when He comes to be glorified by His saints and to be admired by all those who have believed, because our testimony among you was believed.
And in view of this, we always pray for you that our God will consider you worthy of His calling, and will, by His power, fulfill every desire for goodness and the work of faith,
so that the name of our Lord Jesus will be glorified by you, and you by Him, according to the grace of our God and the Lord Jesus Christ.
