2 Thessalonians 1:8-10

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, when He comes to be glorified in His saints on that day [that is, glorified through the changed lives of those who have accepted Him as Savior and have been set apart for His purpose], and to be marveled at among all who have believed, because our testimony to you was believed and trusted [and confirmed in your lives].
