3 To give thanks. He begins with commendation, that he may have occasion to pass on to exhortation, for in this way we have more success among those who have already entered upon the course, when without passing over in silence their former progress, we remind them how far distant they are as yet from the goal, and stir them up to make progress. As, however, he had in the former Epistle commended their faith and love, he now declares the increase of both. And, unquestionably, this course ought to be pursued by all the pious — to examine themselves daily, and see how far they have advanced. This, therefore, is the true commendation of believers — their growing daily in faith and love. When he says always, he means that he is constantly supplied with new occasion. He had previously given thanks to God on their account. He says that he has now occasion to do so again, on the ground of daily progress. When, however, he gives thanks to God on this account, he declares that the enlargements, no less than the beginnings, of faith and love are from him, for if they proceeded from the power of men, thanksgiving would be pretended, or at least worthless. Farther, he shews that their proficiency was not trivial, or even ordinary, but most abundant. So much the more disgraceful is our slowness, inasmuch as we scarcely advance one foot during a long space of time.
As is meet. In these words Paul shews that we are bound to give thanks to God, not only when he does us good, but also when we take into view the favors bestowed by him upon our brethren. For wherever the goodness of God shines forth, it becomes us to extol it. Farther, the welfare of our brethren ought to be so dear to us, that we ought to reckon among our own benefits everything that has been conferred upon them. Nay more, if we consider the nature and sacredness of the unity of Christ’s body, such a mutual fellowship will have place among us, that we shall reckon the benefits conferred upon an individual member as gain to the whole Church. Hence, in extolling God’s benefits, we must always have an eye to the whole body of the Church.
