2 Thessalonians 1:12

12That the name of our Lord Jesus Christ may be glorified. He calls us back to the chief end of our whole life — that we may promote the Lord’s glory. What he adds, however, is more especially worthy of notice, that those who have advanced the glory of Christ will also in their turn be glorified in him. For in this, first of all, the wonderful goodness of God shines forth — that he will have his glory be conspicuous in us who are covered over with ignominy. This, however, is a twofold miracle, that he afterwards irradiates us with his glory, as though he would do the same to us in return. On this account he adds, according to the grace of God and Christ. For there is nothing here that is ours either in the action itself, or in the effect or fruit, for it is solely by the guidance of the Holy Spirit that our life is made to contribute to the glory of God. And the circumstance that so much fruit arises from this ought to be ascribed to the great mercy of God. In the mean time, if we are not worse than stupid, we must aim with all our might at the advancement of the glory of Christ, which is connected with ours. I deem it unnecessary to explain at present in what sense he represents the glory as belonging to God and Christ in common, as I have explained this elsewhere.
