2 Thessalonians 1:7-9

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, 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]. These people will pay the penalty and endure the punishment of everlasting destruction, banished from the presence of the Lord and from the glory of His power
