2 Thessalonians 1:8-10 NIV

[8] He will punish those who do not know God and do not obey the gospel of our Lord Jesus. [9] They will be punished with everlasting destruction and shut out from the presence of the Lord and from the glory of his might [10] on the day he comes to be glorified in his holy people and to be marveled at among all those who have believed. This includes you, because you believed our testimony to you.
