5. But military service implies, what athletic contests do not, vigilant, unwearying, and organized opposition to a vigilant, unwearying, and organized foe. In many athletic contests one's opponent is a rival rather than an enemy. He may defeat us; but he inflicts no injury. He may win the prizes; but he takes nothing of ours. And even in the more deadly conflicts of the amphitheatre the enemy is very different from an enemy in war. The combat is between individuals, not armies; it is the exception and not the rule; it is strictly limited in time and place, not for all times and all places; it is a duel and not a campaign,--still less a prolonged war. Military service is either perpetual warfare or perpetual preparation for it. And just such is the Christian life: it is either a conflict, or a preparation for one. The soldier, so long as he remains in the service, can never say, "I may lay aside my arms and my drill: all enemies are conquered: there will never be another war." And the Christian, so long as he remains in this world, can never think that he may cease to watch and to pray, because the victory is won, and he will never be tempted any more. It is for this reason that he cannot allow himself to be "entangled in the affairs of this life." The soldier on service avoids this error: he knows that it would interfere with his promotion. The Christian must avoid it at least as carefully; for he is always on service, and the loss of promotion is the loss of eternal life.
Observe that St. Paul does not suggest that Christians should keep aloof from the affairs of this life, which would be a flat contradiction of what he teaches elsewhere. The Christian is to "do his own business, and to work with his hands, that he may walk honestly toward them that are without, and may have need of nothing" (1 Thess. iv. 11, 12). He has a duty to perform "in the affairs of this life," but in doing it he is not to be _entangled_ in them. They are means, not ends; and must be made to help him on, not suffered to keep him back. If they become entanglements instead of opportunities, he will soon lose that state of constant preparation and alertness, which is the indispensable condition of success.
The same thought is brought out in the second metaphor by the word "lawfully." The athlete who competes in the games does not receive a crown, unless he has contended _lawfully_, _i.e._, according to rule (=nomimôs, nomos=). Even if he seems to be victorious, he nevertheless is not crowned, because he has violated the well-known conditions. And what is the rule, what are the conditions of the Christian's contest? "If any man would come after Me, let him deny himself, and take up his cross, and follow Me." If we wish to share Christ's victory, we must be ready to share His suffering. No cross, no crown. To try to withdraw oneself from all hardship and annoyance, to attempt to avoid all that is painful or disagreeable, is a violation of the rules of the arena. This, it would appear, Timothy was in some respects tempted to do: and timidity and despondency must not be allowed to get the upper hand. Not that what is painful, or distasteful, or unpopular, is necessarily right; but it is certainly not necessarily wrong: and to try to avoid everything that one dislikes is to ensure being fatally wrong. So that, as Chrysostom says, "it behoves thee not to complain, if thou endurest hardness; but to complain, if thou dost not endure hardness."
Chrysostom and some modern commentators make the striving lawfully include not only the observance of the rules of the contest, but the previous training and preparation. "What is meant by _lawfully_? It is not enough that he is anointed, and even engages, unless he complies with all the regulations of training with respect to diet, temperance, and sobriety, and all the rules of the wrestling-school. Unless, in short, he go through all that is befitting a wrestler, he is not crowned." This makes good sense, if "is not crowned" be interpreted to mean "is not likely to be first," rather than "does not receive the crown, even if he is first." A victorious athlete is rightly deprived of the reward, if he has violated the conditions of the contest: but no one ever yet heard of a victor being refused the prize because he had not trained properly. Moreover, there are enough examples to show that "lawfully" (=nomimôs=) does sometimes include the training as well as the contest.
