This then is one possible meaning of the Apostle's words in the passage before us. Discipline of the body by means of a severe rule of life is profitable for something: but it is not everything. It is not even the chief thing, or anything approaching to the chief thing. The chief thing is godliness. To the value of bodily exercise of this kind there are limits, and rather narrow limits: it "is profitable for _a little_." To the value of godliness there are no limits: it is "profitable for _all_ things." Mortifications of the body may preserve us from sins of the flesh: but they are no certain protection even against these. They are no protection at all--sometimes they are the very reverse of protection--against sins of self-complacency and spiritual pride. Asceticism may exist without godliness; and godliness may exist without asceticism. Bodily mortifications may be useful; but they may also be harmful to both soul and body. Godliness must always be useful to both; can never be harmful to either.
But it is quite possible to understand the expression "bodily exercise," in the sense in which the phrase is most commonly used in ordinary conversation among ourselves. In the text which we are considering it may mean that exercise of the body which we are accustomed to take, some of us of necessity, because the work by which we earn our daily bread involves a great deal of physical exertion; some of us for health's sake, because our work involves a great deal of sitting still; some of us for pleasure, because bodily exercise of various kinds is delightful to us. This interpretation of the Apostle's statement, like the other interpretation, makes good sense of itself and fits the context. And whereas that was in harmony with the opening words of the chapter, this fits the immediate context.
St. Paul has just said "Exercise thyself unto godliness." In using the expression "Exercise thyself" (=gymnaze seauton=) he was of course borrowing, as he so constantly does borrow, from the language which was used respecting gymnastic contests in the public games. The Christian is an athlete, who must train himself and exercise himself for a lifelong contest. He has to wrestle and fight with the powers of evil, that he may win a crown of glory that fadeth not away. How natural, then, that the Apostle, having just spoken of spiritual exercise for the attainment of godliness, should go on to glance at bodily exercise, in order to point out the superiority of the one over the other. The figurative would easily suggest the literal sense; and it is therefore quite lawful to take the words "bodily exercise" in their most literal sense. Perhaps we may go further and say, that this is just one of those cases in which, because the literal meaning makes excellent sense, the literal meaning is to be preferred. Let us then take St. Paul's words quite literally and see what meaning they will yield.
"Bodily exercise is profitable for a little." It is by no means a useless thing. In its proper place it has a real value. Taken in moderation it tends to preserve health and increase strength. It may sometimes be the means of gaining for ourselves and for the circle to which we belong praise and distinction. It makes us more capable of aiding ourselves and others in times of physical danger. It may even be the means of enabling us to save life. By taking us out of ourselves and turning our thoughts into new channels, it is an instrument of mental refreshment, and enables us to return to the main business of our lives with increased intellectual vigour. And beyond all this, if kept within bounds, it has a real moral value. It sometimes keeps us out of mischief by giving us innocent instead of harmful recreation. And bodily training and practice, if loyally carried out, involve moral gains of another kind. Dangerous appetites have to be kept in check, personal wishes have to be sacrificed, good temper has to be cultivated, if success is to be secured for ourselves or the side to which we belong. All this is "profitable" in a very real degree. But the limits to all these good results are evident; and they are somewhat narrow. They are confined to this life, and for the most part to the lower side of it; and they are by no means certain. Only indirectly does bodily exercise yield help to the intellectual and spiritual parts of our nature; and as regards both of them it may easily do more harm than good. Like excessive meat and drink, it may brutalize instead of invigorating. Have we not all of us seen men whose extravagant devotion to bodily exercise has extinguished almost all intellectual interests, and apparently all spiritual interests also?
