2 Thessalonians 1:10-12

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]. With this in view, we constantly pray for you, that our God will count you worthy of your calling [to faith] and with [His] power fulfill every desire for goodness, and complete [your] every work of faith, so that the name of our Lord Jesus will be glorified in you [by what you do], and you in Him, according to the [precious] grace of our God and the Lord Jesus Christ.
