William Burkitt on 2 Thessalonians 1:12

Our apostle declared at verse 10, how Christ should be glorified in his saints hereafter; now he prays that the name of Christ may be glorified in them here.

Where note, That sanctifying grace maketh Christians a glory to the name of Christ, not by adding any glory to him, which before he had not, but by setting forth that glory which he already hath.

Note also, That as the name of Christ is glorified in the saints now, so they shall be glorified in him then, and glorified with him, and by him. The same glory, for kind, shall be put upon the head and members; grace is the only way to glory, and glory will be the certain reward of grace.
