We ought to thank God always for you, brothers and sisters, and rightly so, because your faith flourishes more and more and the love of each one of you all for one another is ever greater.

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].

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.
