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.
12. Greek, "For our wrestling ('the wrestling' in which we are engaged) is not against flesh," &c. Flesh and blood foes are Satan's mere tools, the real foe lurking behind them is Satan himself, with whom our conflict is. "Wrestling" implies that it is a hand-to-hand and foot-to-foot struggle for the mastery: to wrestle successfully with Satan, we must wrestle with God in irresistible prayer like Jacob (Ge 32:24-29; Ho 12:4). Translate, "The principalities … the powers" (Eph 1:21; Col 1:16; see on Eph 3:10). The same grades of powers are specified in the case of the demons here, as in that of angels there (compare Ro 8:38; 1Co 15:24; Col 2:15). The Ephesians had practiced sorcery (Ac 19:19), so that he appropriately treats of evil spirits in addressing them. The more clearly any book of Scripture, as this, treats of the economy of the kingdom of light, the more clearly does it set forth the kingdom of darkness. Hence, nowhere does the satanic kingdom come more clearly into view than in the Gospels which treat of Christ, the true Light.
rulers of the darkness of this world—Greek, "age" or "course of the world." But the oldest manuscripts omit "of world." Translate, "Against the world rulers of this (present) darkness" (Eph 2:2; 5:8; Lu 22:53; Col 1:13). On Satan and his demons being "world rulers," compare Joh 12:31; 14:30; 16:11; Lu 4:6; 2Co 4:4; 1Jo 5:19, Greek, "lieth in the wicked one." Though they be "world rulers," they are not the ruler of the universe; and their usurped rule of the world is soon to cease, when He shall "come whose right it is" (Eze 21:27). Two cases prove Satan not to be a mere subjective fancy: (1) Christ's temptation; (2) the entrance of demons into the swine (for these are incapable of such fancies). Satan tries to parody, or imitate in a perverted way, God's working (2Co 11:13, 14). So when God became incarnate, Satan, by his demons, took forcible possession of human bodies. Thus the demoniacally possessed were not peculiarly wicked, but miserable, and so fit subjects for Jesus' pity. Paul makes no mention of demoniacal possession, so that in the time he wrote, it seems to have ceased; it probably was restricted to the period of the Lord's incarnation, and of the foundation of His Church.
spiritual wickedness—rather as Greek, "The spiritual hosts of wickedness." As three of the clauses describe the power, so this fourth, the wickedness of our spiritual foes (Mt 12:45).
in high places—Greek, "heavenly places": in Eph 2:2, "the air," see on Eph 2:2. The alteration of expression to "in heavenly places," is in order to mark the higher range of their powers than ours, they having been, up to the ascension (Re 12:5, 9, 10), dwellers "in the heavenly places" (Job 1:7), and being now in the regions of the air which are called the heavens. Moreover, pride and presumption are the sins in heavenly places to which they tempt especially, being those by which they themselves fell from heavenly places (Isa 14:12-15). But believers have naught to fear, being "blessed with all spiritual blessings in the heavenly places" (Eph 1:3).
