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.

17. take—a different Greek word from that in Eph 6:13, 16; translate, therefore, "receive," "accept," namely, the helmet offered by the Lord, namely, "salvation" appropriated, as 1Th 5:8, "Helmet, the hope of salvation"; not an uncertain hope, but one that brings with it no shame of disappointment (Ro 5:5). It is subjoined to the shield of faith, as being its inseparable accompaniment (compare Ro 5:1, 5). The head of the soldier was among the principal parts to be defended, as on it the deadliest strokes might fall, and it is the head that commands the whole body. The head is the seat of the mind, which, when it has laid hold of the sure Gospel "hope" of eternal life, will not receive false doctrine, or give way to Satan's temptations to despair. God, by this hope, "lifts up the head" (Ps 3:3; Lu 21:28).

sword of the Spirit—that is, furnished by the Spirit, who inspired the writers of the word of God (2Pe 1:21). Again the Trinity is implied: the Spirit here; and Christ in "salvation" and God the Father, Eph 6:13 (compare Heb 4:12; Re 1:16; 2:12). The two-edged sword, cutting both ways (Ps 45:3, 5), striking some with conviction and conversion, and others with condemnation (Isa 11:4; Re 19:15), is in the mouth of Christ (Isa 49:2), in the hand of His saints (Ps 149:6). Christ's use of this sword in the temptation is our pattern as to how we are to wield it against Satan (Mt 4:4, 7, 10). There is no armor specified for the back, but only for the front of the body; implying that we must never turn our back to the foe (Lu 9:62); our only safety is in resisting ceaselessly (Mt 4:11; Jas 4:7).
