2 Thessalonians 1:5-7

Amplified Bible

⁵ This is a positive proof of the righteous judgment of God [a sign of His fair verdict], so that you will be considered worthy of His kingdom, for which indeed you are suffering. ⁶ For after all it is only just for God to repay with distress those who distress you, ⁷ and to give relief to you who are so distressed and to us as well when the Lord Jesus is revealed from heaven with His mighty angels in a flame of fire,
