2 Thessalonians 1:5-10

which is a manifest token of the righteous judgement of God; to the end that ye may be counted worthy of the kingdom of God, for which ye also suffer: if so be that it is a righteous thing with God to recompense affliction to them that afflict you, and to you that are afflicted rest with us, at the revelation of the Lord Jesus from heaven with the angels of his power in flaming fire, rendering vengeance to them that know not God, and to them that obey not the gospel of our Lord Jesus: who shall suffer punishment, even eternal destruction from the face of the Lord and from the glory of his might, when he shall come to be glorified in his saints, and to be marveled at in all them that believed (because our testimony unto you was believed) in that day.
