No man who warreth He continues to make use of the metaphor which he had borrowed from warfare. Yet, strictly speaking, he formerly called Timothy "a soldier of Christ" metaphorically; but now he compares profane warfare with spiritual and Christian warfare in this sense. "The condition of military discipline is such, that as soon as a soldier has enrolled himself under a general, he leaves his house and all his affairs, and thinks of nothing but war; and in like manner, in order that we may be wholly devoted to Christ, we must be free from all the entanglements of this world." With the affairs of life By "the affairs of life", [1] he means the care of governing his family, and ordinary occupations; as farmers leave their agriculture, and merchants their ships and merchandise, till they have completed the time that they agreed to serve in war. We must now apply the comparison to the present subject, that every one who wishes to fight under Christ must relinquish all the hindrances and employments of the world, and devote himself unreservedly to the warfare. In short, let us remember the old proverb, Hoc age, [2] which means, that in the worship of God, we ought to give such earnestness of attention that nothing else should occupy our thoughts and feelings. The old translation has, "No man that fights for God," etc. But this utterly destroys Paul's meaning. Here Paul speaks to the pastors of the Church in the person of Timothy. The statement is general, but is specially adapted to the ministers of the word. First, let them see what things are inconsistent within their office, that, freed from those things, they may follow Christ. Next, let them see, each for himself, what it is that draws them away from Christ; that this heavenly General may not have less authority over us than that which a mortal man claims for himself over heathen soldiers who have enrolled under him.

1 - "By tou biou pragmateiais is meant the business of life in general, the plural being used with allusion to the various kinds thereof, as agriculture, trade, manufactures, etc. Now, by the Roman law, soldiers were excluded from all such. See Grotius." -- Bloomfield

2 - "Brief, qu'il nous souvienne du proverbe ancien duquel les Latins ont use en faisant leurs sacrifices, Hoc age, c'est a dire, Fay ceci, ou, Pense a ceci, ascavoir que tu as entre mains, lequel signifie, que quand il est question du service de Dieu, il s'y faut tellement employer, que nous ne soyons ententifs ni affectionnez ailleurs." -- "In short, let us remember the old proverb which the Latins used in offering their sacrifices, Hoc age, that is to say, Do this,' or, Think of this,' Do (or think of) what thou hast in hand,' which means, that when the worship of God is the matter in question, we must be employed in it in such a manner that we shall not give our attention or our heart to anything else."

No man that warreth entangleth himself with the affairs of this life - Having alluded to the soldier, and stated one thing in which the Christian minister is to resemble him, another point of resemblance is suggested to the mind of the apostle. Neither the minister nor the soldier is to be encumbered with the affairs of this life, and the one should not be more than the other. This is always a condition in becoming a soldier. He gives up his own business during the time for which he is enlisted, and devotes himself to the service of his country. The farmer leaves his plow, and the mechanic his shop, and the merchant his store, and the student his books, and the lawyer his brief; and neither of them expect to pursue these things while engaged in the service of their country. It would be wholly impracticable to carry on the plans of a campaign, if each one of these classes should undertake to prosecute his private business. See this fully illustrated from the Rules of War among the Romans, by Grotius, "in loc." Roman soldiers were not allowed to marry, or to engage in any husbandry or trade; and they were forbidden to act as tutors to any person, or curators to any man's estate, or proctors in the cause of other men. The general principle was, that they were excluded from those relations, agencies, and engagements, which it was thought would divert their minds from that which was to be the sole object of pursuit. So with the ministers of the gospel. It is equally improper for them to "entangle" themselves with the business of a farm or plantation; with plans of speculation and gain, and with any purpose of worldly aggrandizement. The minister of the gospel accomplishes the design of his appointment only when he can say in sincerity, that he "is not entangled with the affairs of this life;" compare the notes at 1-Corinthians 9:25-27.
That he may please him who hath chosen him to be a soldier - That is, him who has enlisted him, or in whose employ he is. His great object is to approve himself to him. It is not to pursue his own plans, or to have his own will, or to accumulate property or fame for himself. His will is absorbed in the will of his commander, and his purpose is accomplished if he meet with his approbation. Nowhere else is it so true that the will of one becomes lost in that of another, as in the case of the soldier. In an army it is contemplated that there shall be but one mind, one heart, one purpose - that of the commander; and that the whole army shall be as obedient to that as the members of the human body are to the one will that controls all. The application of this is obvious. The grand purpose of the minister of the gospel is to please Christ. He is to pursue no separate plans, and to have no separate will, of his own; and it is contemplated that the whole "Corps" of Christian ministers and members of the churches shall be as entirely subordinate to the will of Christ, as an army is to the orders of its chief.

No man that warreth entangleth, etc. - It is well remarked by Grotius, on this passage, that the legionary soldiers among the Romans were not permitted to engage in husbandry, merchandise, mechanical employments, or any thing that might be inconsistent with their calling. Many canons, at different times, have been made to prevent ecclesiastics from intermeddling with secular employments. The who will preach the Gospel thoroughly, and wishes to give full proof of his ministry, had need to have no other work. He should be wholly in this thing, that his profiting may appear unto all. There are many who sin against this direction. They love the world, and labor for it, and are regardless of the souls committed to their charge. But what are they, either in number or guilt, compared to the immense herd of men professing to be Christian ministers, who neither read nor study, and consequently never improve? These are too conscientious to meddle with secular affairs, and yet have no scruple of conscience to while away time, be among the chief in needless self-indulgence, and, by their burdensome and monotonous ministry, become an incumbrance to the Church! Do you inquire: In what sect or party are these to be found? I answer: In All. Idle drones: -
Fruges consumere nati,
"Born to consume the produce of the soil,"
disgrace every department in the Christian Church. They cannot teach because they will not learn.

No man that warreth entangleth himself with the affairs of (b) [this] life; that he may please him who hath chosen him to be a soldier.
(b) With affairs of household, or other things that belong to other ordinary businesses.

No man that warreth,.... Who is a soldier, and gives himself up to military service, in a literal sense: the Vulgate Latin version, without any authority, adds, "to God"; as if the apostle was speaking of a spiritual warfare; whereas he is illustrating a spiritual warfare by a corporeal one; and observes, that no one, that is in a military state,
entangleth himself with the affairs of this life; with civil affairs, in distinction from military ones. The Roman soldiers might not follow any trade or business of life, or be concerned in husbandry, or merchandise of any sort, but were wholly to attend to military exercises, and to the orders of their general; for to be employed in any secular business was reckoned an entangling of them, a taking of them off from, and an hindrance to their military discipline: and by this the apostle suggests that Christ's people, his soldiers, and especially his ministers, should not he involved and implicated in worldly affairs and cares; for no man can serve two masters, God and mammon; but should wholly give up themselves to the work and service to which they are called; and be ready to part with all worldly enjoyments, and cheerfully suffer the loss of all things, when called to it, for the sake of Christ and his Gospel:
that he may please him who hath chosen him to be a soldier; his captain, or general, who has enlisted him, enrolled and registered him among his soldiers; whom to please should be his chief concern; as it should be the principal thing attended to by a Christian soldier, or minister of the Gospel, not to please men, nor to please himself, by seeking his own ease and rest, his worldly emoluments and advantages, but to please the Lord Christ, in whose book his name is written.

"No one while serving as a soldier."
the affairs of (this) life--"the businesses of life" [ALFORD]; mercantile, or other than military.
him who hath chosen him--the general who at the first enlisted him as a soldier. Paul himself worked at tent-making (Acts 18:3). Therefore what is prohibited here is, not all other save religious occupation, but the becoming entangled, or over-engrossed therewith.

No man that warreth entangleth himself - Any more than is unavoidable. In the affairs of this life - With worldly business or cares. That - Minding war only, he may please his captain. In this and the next verse there is a plain allusion to the Roman law of arms, and to that of the Grecian games. According to the former, no soldier was to engage in any civil employment; according to the latter, none could be crowned as conqueror, who did not keep strictly to the rules of the game.
