2 Thessalonians 1:6-8

1:6 For it is right for God to repay with affliction those who afflict you, 1:7 and to you who are being afflicted to give rest together with us when the Lord Jesus is revealed from heaven with his mighty angels. 1:8 With flaming fire he will mete out punishment on those who do not know God and do not obey the gospel of our Lord Jesus.
