It is not easy to show the precise connexion between these words and those which immediately precede. Possibly it is emotional, rather than logical. The Apostle's heart swells as he contemplates in the Gospel the goodness and faithfulness of God; and though his argument is complete when he has exhibited the Gospel in that light, his mind dwells upon it involuntarily, past the mere point of proof; he lingers over the wonderful experience which Christians have of the rich and sure mercies. Those who try to make out a more precise sequence of thought than this are not very successful. Of course it is apparent that the keynote of the passage is in harmony with that of the previous verses. The ideas of "stablishing," of "sealing," and of an "earnest," are all of one family; they are all, as it were, variations of the one mighty _affirmation_ which has been made of God's promises in Christ. From this point of view they have an argumentative value. They suggest that God, in all sorts of ways, makes believers as sure of the Gospel, and as constant to it, as He has made it sure and certain to them; and thus they exclude more decisively than ever the idea that the minister of the Gospel can be a man of Yes and No. But though this is true, it fails to do justice to the word on which the emphasis falls--namely, God. This, according to some interpreters, is done, if we suppose the whole passage to be, in the first instance, a disclaimer of any false inference which might be drawn from the words, "to the glory of God _by us_." "By us," Paul writes; for it was through the apostolic preaching that men were led to receive the Gospel, to look at God's promises, confirmed in Christ, with an appropriating Amen to His glory; but he hastens to add that it was God himself whose grace in its various workings was the beginning, middle, and end both of their faith and of their preaching. This seems to me rather artificial, and I do not think more than a connexion in sentiment, rather than in argument, can be insisted upon. But setting this question aside, the interpretation of the two verses is of much interest. They contain some of the most peculiar and characteristic words of the New Testament--words to which, it is to be feared, many readers attach no very distinct idea. The simplest plan is to take the assertions one by one, as if God were the subject. Grammatically this is incorrect, for Θεός is certainly the predicate; but for the elucidation of the meaning this may be disregarded.
