Calvin, on the use of God's good gifts

Let this be our principle, that we err not in the use of the gifts of Providence when we refer them to the end for which their author made and destined them, since he created them for our good, and not for our destruction. No man will keep the true path better than he who shall have this end carefully in view. Now then, if we consider for what end he created food, we shall find that he consulted not only for our necessity, but also for our enjoyment and delight. Thus, in clothing, the end was, in addition to necessity, comeliness and honour; and in herbs, fruits, and trees, besides their various uses, gracefulness of appearance and sweetness of smell. Were it not so, the Prophet would not enumerate among the mercies of God “wine that maketh glad the heart of man, and oil to make his face to shine,” (Ps. 104:15). The Scriptures would not everywhere mention, in commendation of his benignity, that he had given such things to men. The natural qualities of things themselves demonstrate to what end, and how far, they may be lawfully enjoyed. Has the Lord adorned flowers with all the beauty which spontaneously presents itself to the eye, and the sweet odour which delights the sense of smell, and shall it be unlawful for us to enjoy that beauty and this odour? What? Has he not so distinguished colours as to make some more agreeable than others? Has he not given qualities to gold and silver, ivory and marble, thereby rendering them precious above other metals or stones? In short, has he not given many things a value without having any necessary use?
