Commentary on Ephesians 6 verses 10–18
Here is a general exhortation to constancy in our Christian course, and to encourage in our Christian warfare. Is not our life a warfare? It is so; for we struggle with the common calamities of human life. Is not our religion much more a warfare? It is so; for we struggle with the opposition of the powers of darkness, and with many enemies who would keep us from God and heaven. We have enemies to fight against, a captain to fight for, a banner to fight under, and certain rules of war by which we are to govern ourselves. "Finally, my brethren (Eph 6:10), it yet remains that you apply yourselves to your work and duty as Christian soldiers." Now it is requisite that a soldier be both stout-hearted and well armed. If Christians be soldiers of Jesus Christ,
I. They must see that they be stout-hearted. This is prescribed here: Be strong in the Lord, etc. Those who have so many battles to fight, and who, in their way to heaven, must dispute every pass, with dint of sword, have need of a great deal of courage. Be strong therefore, strong for service, strong for suffering, strong for fighting. Let a soldier be ever so well armed without, if he have not within a good heart, his armour will stand him in little stead. Note, spiritual strength and courage are very necessary for our spiritual warfare. Be strong in the Lord, either in his cause and for his sake or rather in his strength. We have no sufficient strength of our own. Our natural courage is as perfect cowardice, and our natural strength as perfect weakness; but all our sufficiency is of God. In his strength we must go forth and go on. By the actings of faith, we must fetch in grace and help from heaven to enable us to do that which of ourselves we cannot do, in our Christian work and warfare. We should stir up ourselves to resist temptations in a reliance upon God's all-sufficiency and the omnipotence of his might.
II. They must be well armed: "Put on the whole armour of God (Eph 6:11), make use of all the proper defensitives and weapons for repelling the temptations and stratagems of Satan - get and exercise all the Christian graces, the whole armour, that no part be naked and exposed to the enemy." Observe, Those who would approve themselves to have true grace must aim at all grace, the whole armour. It is called the armour of God, because he both prepares and bestows it. We have no armour of our own that will be armour of proof in a trying time. Nothing will stand us in stead but the armour of God. This armour is prepared for us, but we must put it on; that is, we must pray for grace, we must use the grace given us, and draw it out into act and exercise as there is occasion. The reason assigned why the Christian should be completely armed is that he may be able to stand against the wiles of the devil - that he may be able to hold out, and to overcome, notwithstanding all the devil's assaults, both of force and fraud, all the deceits he puts upon us, all the snares he lays for us, and all his machinations against us. This the apostle enlarges upon here, and shows,
1.What our danger is, and what need we have to put on this whole armour, considering what sort of enemies we have to deal with - the devil and all the powers of darkness: For we wrestle not against flesh and blood, etc., Eph 6:12. The combat for which we are to be prepared is not against ordinary human enemies, not barely against men compounded of flesh and blood, nor against our own corrupt natures singly considered, but against the several ranks of devils, who have a government which they exercise in this world. (1.) We have to do with a subtle enemy, an enemy who uses wiles and stratagems, as Eph 6:11. He has a thousand ways of beguiling unstable souls: hence he is called a serpent for subtlety, an old serpent, experienced in the art and trade of tempting. (2.) He is a powerful enemy: Principalities, and powers, and rulers. They are numerous, they are vigorous; and rule in those heathen nations which are yet in darkness. The dark parts of the world are the seat of Satan's empire. Yea, they are usurping princes over all men who are yet in a state of sin and ignorance. Satan's is a kingdom of darkness; whereas Christ's is a kingdom of light. (3.) They are spiritual enemies: Spiritual wickedness in high places, or wicked spirits, as some translate it. The devil is a spirit, a wicked spirit; and our danger is the greater from our enemies because they are unseen, and assault us ere we are aware of them. The devils are wicked spirits, and they chiefly annoy the saints with, and provoke them to, spiritual wickednesses, pride, envy, malice, etc. These enemies are said to be in high places, or in heavenly places, so the word is, taking heaven (as one says) for the whole expansum, or spreading out of the air between the earth and the stars, the air being the place from which the devils assault us. Or the meaning may be, "We wrestle about heavenly places or heavenly things;" so some of the ancients interpret it. Our enemies strive to prevent our ascent to heaven, to deprive us of heavenly blessings and to obstruct our communion with heaven. They assault us in the things that belong to our souls, and labour to deface the heavenly image in our hearts; and therefore we have need to be upon our guard against them. We have need of faith in our Christian warfare, because we have spiritual enemies to grapple with, as well as of faith in our Christian work, because we have spiritual strength to fetch in. Thus you see your danger.
2.What our duty is: to take and put on the whole armour of God, and then to stand our ground, and withstand our enemies.
(1.)We must withstand, Eph 6:13. We must not yield to the devil's allurements and assaults, but oppose them. Satan is said to stand up against us, Ch1 21:1. If he stand up against us, we must stand against him; set up, and keep up, an interest in opposition to the devil. Satan is the wicked one, and his kingdom is the kingdom of sin: to stand against Satan is to strive against sin. That you may be able to withstand in the evil day, in the day of temptation, or of any sore affliction.
(2.)We must stand our ground: And, having done all, to stand. We must resolve, by God's grace, not to yield to Satan. Resist him, and he will flee. If we distrust our cause, or our leader, or our armour, we give him advantage. Our present business is to withstand the assaults of the devil, and to stand it out; and then, having done all that is incumbent on the good soldiers of Jesus Christ, our warfare will be accomplished, and we shall be finally victorious.
(3.)We must stand armed; and this is here most enlarged upon. Here is a Christian in complete armour: and the armour is divine: Armour of God, armour of light, Rom 13:12. Armour of righteousness, Co2 6:7. The apostle specifies the particulars of this armour, both offensive and defensive. The military girdle or belt, the breast-plate, the greaves (or soldier's shoes), the shield, the helmet, and the sword. It is observable that, among them all, there is none for the back; if we turn our back upon the enemy, we lie exposed. [1.] Truth or sincerity is our girdle, Eph 6:14. It was prophesied of Christ (Isa 11:5) that righteousness should be the girdle of his loins and faithfulness the girdle of his reins. That which Christ was girded with all Christians must be girded with. God desires truth, that is, sincerity, in the inward parts. This is the strength of our loins; and it girds on all other pieces of our armour, and therefore is first mentioned. I know no religion without sincerity. Some understand it of the doctrine of the truths of the gospel: they should cleave to us as the girdle does to the loins, Jer 13:11. This will restrain from libertinism and licentiousness, as a girdle restrains and keeps in the body. This is the Christian soldier's belt: ungirded with this, he is unblessed. [2.] Righteousness must be our breast-plate. The breast-plate secures the vitals, shelters the heart. The righteousness of Christ imputed to us is our breast-plate against the arrows of divine wrath. The righteousness of Christ implanted in us is our breast-plate to fortify the heart against the attacks which Satan makes against us. The apostle explains this in Th1 5:8, Putting on the breast-plate of faith and love. Faith and love include all Christian graces; for by faith we are united to Christ and by love to our brethren. These will infer a diligent observance of our duty to God, and a righteous deportment towards men, in all the offices of justice, truth, and charity. [3.] Resolution must be as the greaves to our legs: And their feet shod with the preparation of the gospel of peace, Eph 6:15. Shoes, or greaves of brass, or the like, were formerly part of the military armour (Sa1 17:6): the use of them was to defend the feet against the gall-traps, and sharp sticks, which were wont to be laid privily in the way, to obstruct the marching of the enemy, those who fell upon them being unfit to march. The preparation of the gospel of peace signifies a prepared and resolved frame of heart, to adhere to the gospel and abide by it, which will enable us to walk with a steady pace in the way of religion, notwithstanding the difficulties and dangers that may be in it. It is styled the gospel of peace because it brings all sorts of peace, peace with God, with ourselves, and with one another. It may also be meant of that which prepares for the entertainment of the gospel, namely, repentance. With this our feet must be shod: for by living a life of repentance we are armed against temptations to sin, and the designs of our great enemy. Dr. Whitby thinks this may be the sense of the words: "That you may be ready for the combat, be shod with the gospel of peace, endeavour after that peaceable and quiet mind which the gospel calls for. Be not easily provoked, nor prone to quarrel: but show all gentleness and all long-suffering to all men, and this will certainly preserve you from many great temptations and persecutions, as did those shoes of brass the soldiers from those galltraps," etc. [4.] Faith must be our shield: Above all, or chiefly, taking the shield of faith, Eph 6:16. This is more necessary than any of them. Faith is all in all to us in an hour of temptation. The breast-plate secures the vitals; but with the shield we turn every way. This is the victory over the world, even our faith. We are to be fully persuaded of the truth of all God's promises and threatenings, such a faith being of great use against temptations. Consider faith as it is the evidence of things not seen and the substance of things hoped for, and it will appear to be of admirable use for this purpose. Faith, as receiving Christ and the benefits of redemption, so deriving grace from him, is like a shield, a sort of universal defence. Our enemy the devil is here called the wicked one. He is wicked himself, and he endeavours to make us wicked. His temptations are called darts, because of their swift and undiscerned flight, and the deep wounds that they give to the soul; fiery darts, by way of allusion to the poisonous darts which were wont to inflame the parts which were wounded with them, and therefore were so called, as the serpents with poisonous stings are called fiery serpents. Violent temptations, by which the soul is set on fire of hell, are the darts which Satan shoots at us. Faith is the shield with which we must quench these fiery darts, wherein we should receive them, and so render them ineffectual, that they may not hit us, or at least that they may not hurt us. Observe, Faith, acted upon the word of God and applying that, acted upon the grace of Christ and improving that, quenches the darts of temptation. [5.] Salvation must be our helmet (Eph 6:17); that is, hope, which has salvation for its object; so Th1 5:8. The helmet secures the head. A good hope of salvation, well founded and well built, will both purify the soul and keep it from being defiled by Satan, and it will comfort the soul and keep it from being troubled and tormented by Satan. He would tempt us to despair; but good hope keeps us trusting in God, and rejoicing in him. [6.] The word of God is the sword of the Spirit. The sword is a very necessary and useful part of a soldier's furniture. The word of God is very necessary, and of great use to the Christian, in order to his maintaining the spiritual warfare and succeeding in it. It is called the sword of the Spirit, because it is of the Spirit's inditing and he renders it efficacious and powerful, and sharper than a two-edged sword. Like Goliath's sword, none like that; with this we assault the assailants. Scripture-arguments are the most powerful arguments to repel temptation with. Christ himself resisted Satan's temptations with, It is written, Mat 4:4, Mat 4:6, Mat 4:7, Mat 4:10. This, being hid in the heart, will preserve from sin (Psa 119:11), and will mortify and kill those lusts and corruptions that are latent there. [7.] Prayer must buckle on all the other parts of our Christian armour, Eph 6:18. We must join prayer with all these graces, for our defence against these spiritual enemies, imploring help and assistance of God, as the case requires: and we must pray always. Not as though we were to do nothing else but pray, for there are other duties of religion and of our respective stations in the world that are to be done in their place and season; but we should keep up constant times of prayer, and be constant to them. We must pray upon all occasions, and as often as our own and others' necessities call us to it. We must always keep up a disposition to prayer, and should intermix ejaculatory prayers with other duties, and with common business. Though set and solemn prayer may sometimes be unseasonable (as when other duties are to be done), yet pious ejaculations can never be so. We must pray with all prayer and supplication, 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 thanksgivings for favours received. We must pray in the Spirit; our spirits must be employed in the duty and we must do it by the grace of God's good Spirit. We must watch thereunto, endeavouring to keep our hearts in a praying frame, and taking all occasions, and improving all opportunities, for the duty: we must watch to all the motions of our own hearts towards the duty. When God says, Seek my face, our hearts must comply, Psa 27:8. This we must do with all perseverance. We must abide by the duty of prayer, whatever change there may be in our outward circumstances; and we must continue in it as long as we live in the world. We must persevere in a particular prayer; not cutting it short, when our hearts are disposed to enlarge, and there is time for it, and our occasions call for it. We must likewise persevere in particular requests, notwithstanding some present discouragements and repulses. And we must pray with supplication, not for ourselves only, but for all saints; for we are members one of another. Observe, None are so much saints, and in so good a condition in this world, but they need our prayers, and they ought to have them. The apostle passes hence to the conclusion of the epistle.
“Finally, dearly beloved, be strong in the Lord, and in the power of His might. Put on the armour of God, that ye may be able to stand against the wiles of the devil; for we wrestle not against flesh and blood, but against principalities and powers, against the rulers of the darkness of this world, against spiritual wickedness in heavenly places (cœlestibus). Wherefore take unto you the armour of God, that ye may be able to withstand in the evil day, and to stand perfect in all (omnibus perfecti). Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness, and your feet shod with the preparation of the Gospel of peace; in all (in omnibus) taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked one. And take the helmet of salvation, and the sword of the Spirit, which is the word of God.”2875 It is our wish, brother, that those things which we have written to you should be made known generally to all, in order that things which touch the others should be made known to all. May Almighty God protect you, brother, and all our brethren everywhere situate, even to the end,—even He who has thought good to redeem the whole world, our Lord Jesus Christ, who is blessed for ever. Amen.
To be “strong in the Lord” is to be strengthened in word and wisdom and the contemplation of truth. All these qualities are encompassed in the titles applying to Christ. The greatest of these is the strength of his might, which is stronger than all human virtues combined. Moral corruption lacks power in his presence. This one virtue, being strong in the Lord, is inconceivably powerful. Those who are wise in these matters call it the strength of his might. It has some analogy with bodily might but far exceeds it. This strength is beautiful, as a strong body is beautiful.
"Finally," saith he, "be strong in the Lord."
Whenever the discourse is about to conclude, he always employs this turn. Said I not well from the first, that every man's house is a camp in itself? For look, having disposed of the several offices, he proceeds to arm them, and to lead them out to war. If no one usurps the other's office, but every one remains at his post, all will be well ordered.
"Be strong," saith he, "in the Lord, and in the strength of His might."
That is, in the hope which we have in Him, by means of His aid. For as he had enjoined many duties, which were necessary to be done, fear not, he seems to say, cast your hope upon the Lord, and He will make all easy.
But now, when any one is going to the theater, or going off to the bath, he drags all his servants after him; but when he goes to church, not for a moment; nor does he compel them to attend and hear. Now how shall thy servant listen, when thou his master art attending to other things? Hast thou purchased, hast thou bought thy slave? Before all things enjoin him what God would have him do, to be gentle towards his fellow-servants, and to make much account of virtue.
Every one's house is a city; and every man is a prince in his own house. That the house of the rich is of this character, is plain enough, where there are both lands, and stewards, and rulers over rulers. But I say that the house of the poor also is a city. Because here too there are offices of authority; for instance, the husband has authority over the wife, the wife over the servants, the servants again over their own wives; again the wives and the husbands over the children. Does he not seem to you to be, as it were, a sort of king, having so many authorities under his own authority? and that it were meet that he should be more skilled both in domestic and general government than all the rest? For he who knows how to manage these in their several relations, will know how to select the fittest men for offices, yes, and will choose excellent ones. And thus the wife will be a second king in the house, lacking only the diadem; and be who knows how to choose this king, will excellently regulate all the rest.
Evagrius said, ‘If your attention falters, pray. As it is written, pray in fear and trembling (cf. Phil. 2:12), earnestly and watchfully. We ought to pray like that, especially because our unseen and wicked enemies are trying to hinder us forcefully.’
She also said, ‘The devil sometimes sends a severe fast which is too prolonged; the devil’s disciples do this as well as holy men. How do we distinguish the fasting of our God and King from the fasting of that tyrant the devil? Clearly by its moderation. Throughout your life, then, you ought to keep an unvarying rule of fasting. Do you fast four or five days on end and then lose your spiritual strength by eating a feast? That really pleases the devil! Everything which is extreme is destructive. So do not suddenly throw away your armour, or you may be found unarmed in the battle and easily captured. Our body is the armour, our soul is the warrior. Take care of both, and you will be ready for whatever comes.’

SUMMARY
Ephesians 6:10 serves as a crucial transitional and foundational command, urging believers to draw their spiritual strength not from human capability but exclusively from their union with the Lord Jesus Christ and the immeasurable, inherent power of His divine might. It introduces the subsequent discourse on spiritual warfare, establishing that reliance on God's omnipotence is the prerequisite for standing firm against the forces of evil and living out the Christian life effectively.
CONTEXT
EXPOSITION AND ANALYSIS
Key Word Analysis
Verse Breakdown
Literary Devices
Ephesians 6:10 effectively employs several literary devices to convey its profound message. The Imperative Mood of "be strong" functions as a direct command, underscoring the urgency and necessity of this spiritual posture for believers. The use of Repetition and Amplification in the phrase "in the Lord, and in the power of his might" serves to emphasize the singular, divine source of strength. By using two distinct Greek words for "power" (kratos and ischys), Paul creates a Hendiadys, where two nouns connected by "and" convey a single, intensified concept—the overwhelming, active manifestation of God's inherent strength. This phrase also functions as a Metaphor, portraying spiritual strength as something derived from an external, divine reservoir, rather than an internal human capacity, thereby setting the stage for the subsequent military imagery of the armor of God. The address "my brethren" is an example of Apostrophe, directly engaging the audience with a term of affection and shared identity, fostering a sense of communal responsibility in the spiritual battle.
THEOLOGICAL AND THEMATIC CONNECTIONS
This verse is a profound theological statement on the nature of Christian strength, asserting that genuine spiritual vitality and resilience are not products of human effort or self-will, but are entirely derived from God's inexhaustible power. It counters any notion of self-sufficiency in the spiritual life, redirecting the believer's gaze from their own limitations to the boundless might of the Creator and Redeemer. This divine empowerment is essential for navigating the complexities of life, resisting temptation, and standing firm against the spiritual forces of evil. It speaks to the core Christian doctrine of dependence on God, where human weakness becomes the conduit for divine strength, ultimately glorifying God.
REFLECTION AND APPLICATION
Ephesians 6:10 serves as a vital anchor for every believer, grounding our spiritual effectiveness in the unshakeable reality of God's power. In a world that often champions self-reliance and personal achievement, this verse calls us to a posture of humble dependence. It reminds us that our battles—whether against temptation, despair, injustice, or the direct onslaughts of evil—are not fought in our own strength, but in the infinite might of the Lord. Practically, this means cultivating a deep, abiding relationship with Christ through prayer, Scripture, and worship, recognizing that it is through His indwelling Spirit that we are empowered. It encourages us to cease striving in our own limited capacity and instead to lean fully into the divine enablement that flows from our union with Him. This strength is not for personal glory but for God's purposes, enabling us to stand firm, live righteously, and fulfill our calling in His kingdom.
Questions for Reflection
FAQ
What does it mean to "be strong in the Lord"?
Answer: To "be strong in the Lord" means to draw your strength, courage, and ability from your relationship with Jesus Christ, rather than from your own human capabilities, willpower, or circumstances. It implies a conscious reliance on His divine power, which is made available to believers through the Holy Spirit. This strength is not self-generated but is a gift received through faith and spiritual union with Him, enabling believers to live righteously, endure trials, and stand firm against spiritual opposition, as further detailed in Ephesians 6:11.
Why is it important to be strong "in the power of his might" specifically?
Answer: The phrase "in the power of his might" emphasizes the source and nature of the strength available to believers. "Power" (kratos) refers to God's active, manifest dominion and strength, while "might" (ischys) refers to His inherent, intrinsic, and inexhaustible strength. By combining these, Paul underscores that the strength we receive is not a small measure, but flows from the very core of God's omnipotence. This divine, overwhelming power is necessary because the spiritual battle believers face is not against human adversaries but against formidable spiritual forces, as highlighted in Ephesians 6:12. Human strength is utterly insufficient for such a conflict.
CHRIST-CENTERED FULFILLMENT
Ephesians 6:10 finds its ultimate Christ-centered fulfillment in the person and work of Jesus Christ, who is the embodiment of God's strength and the very source of our empowerment. The command to "be strong in the Lord" points directly to our union with Christ, for it is "in Him" that we have been blessed with every spiritual blessing (Ephesians 1:3). Christ Himself is the "power of God" (1 Corinthians 1:24), and through His resurrection, God demonstrated the "working of His mighty power" (Ephesians 1:19-20). Our strength is not merely from Christ, but in Christ, meaning it flows from our vital connection to Him, much like a branch draws life from the vine (John 15:5). He is our indwelling strength, enabling us to do all things through Him who strengthens us (Philippians 4:13). Thus, the call to be strong is a call to abide more deeply in the one who has already triumphed over all spiritual powers and authorities, making His victory our strength (Colossians 2:15).
