2 Thessalonians 1:8-10

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. 1:9 They will undergo the penalty of eternal destruction, away from the presence of the Lord and from the glory of his strength, 1:10 when he comes to be glorified among his saints and admired on that day among all who have believed – and you did in fact believe our testimony.
