(14-17) In this magnificent passage, while it would be unreasonable to look for formal and systematic exactness, it is clear that (as usual in St. Paul's most figurative passages) there runs through the whole a distinct method of idea. Thus (1) the order in which the armour in enumerated is clearly the order in which the armour of the Roman soldier was actually put on. It nearly corresponds with the invariable order in which Homer describes over and over again the arming of his heroes. First the belt and the corselet, which met and together formed the body armour; then the sandals; next the shield, and after this (for the strap of the great shield could hardly pass over the helmet) the helmet itself; then the soldier was armed, and only had to take up the sword and spear. It is curious to note that St. Paul omits the spear (the pilum of the Roman soldier)--exactly that part of his equipment which, when on guard within, the soldier would not be likely to assume. (2) Again, since "to put on the armour of light" is to "put on the Lord Jesus Christ," it follows that the various parts of the defensive armour are the various parts of the image of the Lord Jesus Christ; hence they are properly His, and are through His gift appropriated by us. Thus the "righteousness" is clearly the righteousness of Christ, realised in us (comp. Philippians 3:9); the sandals, which give firm footing, are the gospel of our peace in Him; the salvation is His salvation worked out in us. Only the sword is in no sense our own: it is the "Word of God" wielded by us, but in itself "living and powerful and sharp" (Hebrews 4:12).

(14) Your loins girt about with truth, and having on the breastplate of righteousness.--There is here an obvious reference to two passages of Isaiah (Isaiah 11:5; Isaiah 59:17), "Righteousness shall be the girdle of his loins," "He put on righteousness as a breastplate." Truth and righteousness are virtually identical, or, at least, inseparable. Hence they are compared to the strong belt, and the breastplate continuous with it, forming together the armour of the body. Perhaps "truth" is taken as the belt because it is the one bond both of society and of individual character. But it is in the two together that men stand "armed strong in honesty." In 1Thessalonians 5:8, the metaphor is different and perhaps less exact. There the breastplate is the "breastplate of faith and love"--that which here is the shield.

Verse 14. - Stand therefore, having girt about your loins with truth. The "stand" in ver. 13 denotes the end of the conflict; this "stand" is at the beginning. Obviously there must be a firm stand at the beginning if there is to be at the end. In order to this, we must fasten the girdle round our loins - viz, truth, here used in a comprehensive sense, denoting honesty; sincerity of profession in opposition to all sham, levity, hypocrisy; and likewise the element of "truth in Jesus" (Ephesians 5:21), the substance of the gospel revelation. We are to gird ourselves in truth, ἐν ἀληθείᾳ, establishing ourselves in that element, wrapping it round us; ἐν ἀληθείᾳ, literally, "girded in truth." And having put on the breastplate of righteousness. Comp. Ephesians 5:24, for at least one element of the righteousness - righteousness wrought in us by the Holy Ghost after the image of Christ. But a more comprehensive use of the term is not excluded - the whole righteousness that we derive from Christ - righteousness imputed and righteousness infused.

6:10-18 Spiritual strength and courage are needed for our spiritual warfare and suffering. Those who would prove themselves to have true grace, must aim at all grace; and put on the whole armour of God, which he prepares and bestows. The Christian armour is made to be worn; and there is no putting off our armour till we have done our warfare, and finished our course. The combat is not against human enemies, nor against our own corrupt nature only; we have to do with an enemy who has a thousand ways of beguiling unstable souls. The devils assault us in the things that belong to our souls, and labour to deface the heavenly image in our hearts. We must resolve by God's grace, not to yield to Satan. Resist him, and he will flee. If we give way, he will get ground. If we distrust either our cause, or our Leader, or our armour, we give him advantage. The different parts of the armour of heavy-armed soldiers, who had to sustain the fiercest assaults of the enemy, are here described. There is none for the back; nothing to defend those who turn back in the Christian warfare. Truth, or sincerity, is the girdle. This girds on all the other pieces of our armour, and is first mentioned. There can be no religion without sincerity. The righteousness of Christ, imputed to us, is a breastplate against the arrows of Divine wrath. The righteousness of Christ implanted in us, fortifies the heart against the attacks of Satan. Resolution must be as greaves, or armour to our legs; and to stand their ground or to march forward in rugged paths, the feet must be shod with the preparation of the gospel of peace. Motives to obedience, amidst trials, must be drawn from a clear knowledge of the gospel. Faith is all in all in an hour of temptation. Faith, as relying on unseen objects, receiving Christ and the benefits of redemption, and so deriving grace from him, is like a shield, a defence every way. The devil is the wicked one. Violent temptations, by which the soul is set on fire of hell, are darts Satan shoots at us. Also, hard thoughts of God, and as to ourselves. Faith applying the word of God and the grace of Christ, quenches the darts of temptation. Salvation must be our helmet. A good hope of salvation, a Scriptural expectation of victory, will purify the soul, and keep it from being defiled by Satan. To the Christian armed for defense in battle, the apostle recommends only one weapon of attack; but it is enough, the sword of the Spirit, which is the word of God. It subdues and mortifies evil desires and blasphemous thoughts as they rise within; and answers unbelief and error as they assault from without. A single text, well understood, and rightly applied, at once destroys a temptation or an objection, and subdues the most formidable adversary. Prayer must fasten all the other parts of our Christian armour. There are other duties of religion, and of our stations in the world, but we must keep up times of prayer. Though set and solemn prayer may not be seasonable when other duties are to be done, yet short pious prayers darted out, always are so. We must use holy thoughts in our ordinary course. A vain heart will be vain in prayer. We must pray with all kinds of prayer, public, private, and secret; social and solitary; solemn and sudden: with all the parts of prayer; confession of sin, petition for mercy, and thanksgiving for favours received. And we must do it by the grace of God the Holy Spirit, in dependence on, and according to, his teaching. We must preserve in particular requests, notwithstanding discouragements. We must pray, not for ourselves only, but for all saints. Our enemies are mighty, and we are without strength, but our Redeemer is almighty, and in the power of his mighty we may overcome. Wherefore we must stir up ourselves. Have not we, when God has called, often neglected to answer? Let us think upon these things, and continue our prayers with patience.Stand therefore,.... Keep your ground, do not desert the army, the church of Christ, nor his cause; continue in the station in which you are placed, keep your post, be upon your watch, stand upon your guard:

having your loins girt about with truth; by which is meant the Gospel, and the several doctrines of it; see Ephesians 1:13; and to have the loins girt with it, shows, that it should be near and close to the saints, and never departed from; and that it is a means of keeping them close to God and Christ, and of strengthening them against the assaults and attacks of Satan; and is of great use in the Christians' spiritual conflict with their enemies; the girdle is a part of armour, and so considerable as sometimes to be put for the whole, Isaiah 5:27; and here it is mentioned in the first place:

and having on the breastplate of righteousness; in allusion to Isaiah 59:17, meaning not works of righteousness done by men, though these are a fence when rightly used against the reproaches and charges of the enemy, as they were by Samuel, 1 Samuel 12:3, but rather the graces of faith and love, 1 Thessalonians 5:8, though faith has another place in the Christian armour, afterwards mentioned; wherefore it seems best to understand this of the righteousness of Christ, which being imputed by God, and received by faith, is a guard against, and repels the accusations and charges of Satan, and is a security from all wrath and condemnation.
