2 Thessalonians 1:6-8

Amplified Bible

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, ⁸ dealing out [full and complete] vengeance to those who do not [seek to] know God and to those who ignore and refuse to obey the gospel of our Lord Jesus [by choosing not to respond to Him].
