Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.

People's New Testament

6:11 Put on the whole armour of God. The ancient soldier was not equipped for war until he had put on his armor. Paul was at that time a prisoner, probably living near the praetorian camp in Rome, as he was by the Roman customs under the charge of the praetorian prefect. It is possible that the figure was suggested by the sights he so often witnessed. See PNT 1Th 5:8.

That ye may be able to stand against the wiles of the devil. The great enemy. The armor was designed not only to protect, but there were weapons also with which to assail him.

Wesley's Notes

6:11 Put on the whole armour of God - The Greek word means a complete suit of armour. Believers are said to put on the girdle, breastplate, shoes; to take the shield of faith, and sword of the Spirit. The whole armour - As if the armour would scarce do, it must be the whole armour. This is repeated, ver.13, because of the strength and subtilty of our adversaries, and because of an evil day of sore trial being at hand.

Jamieson-Fausset-Brown Bible Commentary

11. the whole armour-the armor of light (Ro 13:12); on the right hand and left (2Co 6:7). The panoply offensive and defensive. An image readily suggested by the Roman armory, Paul being now in Rome. Repeated emphatically, Eph 6:13. In Ro 13:14 it is, "Put ye on the Lord Jesus Christ"; in putting on Him, and the new man in Him, we put on "the whole armor of God." No opening at the head, the feet, the heart, the belly, the eye, the ear, or the tongue, is to be given to Satan. Believers have once for all overcome him; but on the ground of this fundamental victory gained over him, they are ever again to fight against and overcome him, even as they who once die with Christ have continually to mortify their members upon earth (Ro 6:2-14; Col 3:3, 5).

of God-furnished by God; not our own, else it would not stand (Ps 35:1-3). Spiritual, therefore, and mighty through God, not carnal (2Co 10:4).

wiles-literally, "schemes sought out" for deceiving (compare 2Co 11:14).

the devil-the ruling chief of the foes (Eph 6:12) organized into a kingdom of darkness (Mt 12:26), opposed to the kingdom of light.

Matthew Henry's Concise Commentary

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.
