Ephesians 6

Verses 10–20 WEB Voices

Paul’s closing charge to the Ephesian church—put on God’s armor, stand against the devil’s schemes, and pray.

Ephesians 6:10

10Finally, be strong in the Lord and in the strength of his might.

Arminian

“Finally” turns the church from household tables to the field. “Be strong” is a charge: nothing less will suffice for this fight, and to remain weak is the way to perish. The strength is “in the Lord” and “in the strength of his might”—grace does the enabling, not unaided will. Arminian readers insist that this might is sincerely given to believers who must take it up; remaining unarmed is neglected assistance, not a failure of the Lord’s offer.

Reformed

The command is meant seriously, but the location of power is decisive: “in the Lord” and “in the strength of his might.” Weakness is assumed; God supplies the vigor. Reformed reading hears comfort before burden: the soldier does not manufacture might. Those in Christ are made strong by the Lord who already reigns over the powers named in the next verses—His provision, not our nerve, is the strength of the fight.

Key contrast Arminians detect a command that can be neglected—grace enables a fight we must actually fight. The Reformed hear the same command as a summons into God’s own power, which He actually supplies to those who are in Christ.

Ephesians 6:11

11Put on the whole armor of God, that you may be able to stand against the wiles of the devil.

Arminian

Putting on the whole armor is the believer’s act. God provides the panoply; we must don it. The aim is to stand against the devil’s schemes—craft, not only force. Grace makes standing possible; refusing the armor leaves a Christian exposed in a war that will not pause. Pastoral Arminian note: the fight is not imaginary, and “put on” can be neglected even by those who know the pieces by name.

Reformed

The armor is “of God”—His provision, not homemade piety. He furnishes weapons so that standing against the devil’s schemes is actually possible. The wiles are true, but so is the panoply God gives His people. Those united to Christ are not left to invent their own defense; the armor He issues is what keeps them able to stand.

Key contrast Both camps say the armor is God’s. Arminians stress the duty to put it on, a fight that can be neglected; the Reformed stress that God’s provision actually keeps those in Christ able to stand.

Ephesians 6:12

12For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world’s rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places.

Arminian

The wrestling is spiritual: not chiefly flesh and blood, but rulers, authorities, cosmic powers, and spiritual forces of evil. Treating people as the main enemy misses the war. Believers must engage this fight under enabling grace—alert, not naïve about a devil who uses both force and fraud. The struggle can be ignored; it cannot be wished away.

Reformed

Human opponents are not the last enemy; the conflict is with powers no flesh can match. That fact drives us off self-reliance onto the Lord’s might. Naming the foe as supernatural does not make the outcome uncertain for those God arms. The darkness is true; it is not a rival deity. The fight is spiritual, and the strength for it remains His.

Ephesians 6:13

13Therefore put on the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand.

Arminian

Take up repeats the call: the armor must be assumed, not admired from a distance. The evil day is coming—trial, temptation, perhaps death. “Having done all, to stand” pictures a contest that can be neglected. Grace enables endurance to the end; standing is Spirit-empowered perseverance, not a spectator sport. Keep the armor on, watch and pray, and so endure.

Reformed

The repetition is mercy: God again offers the whole armor. “That you may be able to withstand” carries a promise of ability, not a bare wish. In the evil day those who fight with this assistance will stand. The command to take up armor is how God keeps His people, not a hint that He might fail them. Having done all, they stand because His power meets the day.

Key contrast Arminians treat taking up and standing as a neglectable fight under assisting grace. The Reformed hear a promise inside the command: God’s power will meet the evil day for those in Christ.

Ephesians 6:14

14Stand therefore, having the utility belt of truth buckled around your waist, and having put on the breastplate of righteousness,

Arminian

Stand, then fasten truth and put on righteousness. Truth is more than correct doctrine—it is truth in the inward parts and a ready will. The breastplate guards the conscience by a holy life, the righteousness in which Christ will present His people. No back-armor is listed: we face the enemy. Grace forms this integrity; leaving the belt unbuckled is how a soldier is undone in the evil day.

Reformed

Standing is the posture of those already armed by God. The utility belt of truth buckled around your waist, and breastplate of righteousness are His gifts worn in union with Christ—sincerity of heart and a life ordered by the gospel. Reformed readers also remember that the righteousness that finally holds in battle is Christ’s. The command to stand assumes God has given what the command requires.

Ephesians 6:15

15and having fitted your feet with the preparation of the Good News of peace,

Arminian

Gospel shoes mean readiness: peace with God preparing every step. The race is long; feet must not slip. Wesleyan Arminians hear an ongoing duty—hold the Good News of peace, above heart and walk, so rough ways can be trod to the end. Neglect of this readiness is how a soldier stumbles even in issued boots. Grace gives the peace; we must keep it on.

Reformed

The gospel of peace is the message of reconciliation with God; it is given, not achieved. Shoes here are God’s provision for the march. The same gospel that made peace also makes us ready. Stability in conflict comes from the announcement of peace, not from the soldier’s nerve. The readiness is given by the gospel—gift before gait.

Ephesians 6:16

16above all, taking up the shield of faith, with which you will be able to quench all the fiery darts of the evil one.

Arminian

In every circumstance take up the shield of faith—continually exercise a lively trust. Faith extinguishes the evil one’s flaming darts: sudden injections, furious temptations. Grace enables this faith; it remains a shield we must actually raise. A neglected shield is no shield in the hour of assault. The you can extinguish is a capacity given to believers who use it.

Reformed

Faith is God’s appointed shield, and it works. The darts are authentic and fiery; the means God gives actually quench them. Taking up faith is not creating faith from nothing but using the trust the Spirit has wrought. Those in Christ are not left to the devil’s fire without a shield that holds. All the darts can be extinguished because the Giver of faith is faithful.

Key contrast Arminians emphasize taking up faith as a living act that can be omitted in the moment of trial. The Reformed emphasize that the shield God gives actually extinguishes the darts for those who belong to Christ.

Ephesians 6:17

17And take the helmet of salvation, and the sword of the Spirit, which is the word of God;

Arminian

Take the helmet of salvation and the sword of the Spirit. Hope of salvation guards the head; the word is the one offensive weapon, edged and wielded by faith. Even a Christian covered head to foot is foiled if this sword is neglected. Grace puts the word in our hand; we must take it up. The fight is not in doubt, and the next verse’s prayer must not be skipped as if armor without asking were enough.

Reformed

Salvation as helmet is the hope God promises—the head is kept by what He has done and will complete. The sword is the Spirit’s, which is the word of God: God’s own weapon, not our cleverness. He does not send His people into the dark unarmed. The word He speaks is sufficient to slay the lie, and the helmet He gives actually keeps those in Christ.

Ephesians 6:18

18with all prayer and requests, praying at all times in the Spirit, and being watchful to this end in all perseverance and requests for all the saints.

Arminian

Prayer is not an appendix; it is how the armor is kept in use. Pray at all times in the Spirit, with every kind of prayer, alert and persevering, and intercede for all the saints. This can be neglected: some are careful in one kind of prayer and slack in others. Assisting grace makes true prayer possible; remaining prayerless is to lay the sword down. Watch, continue, and wrestle for the whole household of faith.

Reformed

Praying in the Spirit is faith’s chief exercise and the way every blessing is obtained. Perseverance in prayer is itself a gift the Spirit works. We pray because God hears, and we pray for all the saints because He binds the church together. Alertness is commanded; the Spirit who indwells also keeps the watchers. Prayer is not self-rescue but the appointed means by which the Lord keeps His people.

Key contrast Arminians stress prayer as a duty that can be omitted, without which the armored Christian still falls. The Reformed stress that praying in the Spirit is God’s own means of keeping His people to the end.

Ephesians 6:19

19Pray for me, that utterance may be given to me in opening my mouth, to make known with boldness the mystery of the Good News,

Arminian

Even Paul asks for prayer—that utterance may be given and his mouth opened boldly to proclaim the mystery. Apostolic boldness is requested, not presumed. This is the church’s partnership: grace is given through asking, and even gifted ministers can falter if prayer is neglected. The gospel remains a mystery to be spoken; the speaker remains a man who must be helped.

Reformed

“That utterance may be given to me” locates utterance in God’s gift. The mystery of the gospel is proclaimed because God opens the mouth. The apostle’s request does not signal an uncertain gospel but ordained means. God uses the church’s prayers to give His ambassador the boldness required. The same might that arms the saints supplies the preacher’s speech.

Ephesians 6:20

20for which I am an ambassador in chains; that in it I may speak boldly, as I ought to speak.

Arminian

He is an ambassador in chains—glory without pomp. He asks to declare the gospel boldly as he ought. The “ought” remains a living obligation under grace: chains do not cancel the call, nor does grace cancel the need to speak. Believers pray so that this duty is not neglected in fear. The fight that began with “be strong” ends in a prisoner still asking for strength to open his mouth.

Reformed

The ambassador belongs to the King who sent him; chains cannot revoke the commission. Bold speech is how he “ought” to speak because God has assigned the message. The gospel is not chained. The same might that arms the church keeps the imprisoned preacher able to declare it. Prayer for boldness is how the Lord actually keeps His witness standing in the evil day.

Historic quotes

Voices from both camps

What older interpreters in each camp said about Paul’s closing charge to the Ephesian church—put on God’s armor, stand against the devil’s schemes, and pray.

Arminian Notable voices

“Be strong - Nothing less will suffice for such a fight: to be weak, and remain so, is the way to perish. Put on the whole armour of God - The Greek word means a complete suit of armour. 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. And having done all, to stand - That ye may still keep on your armour, still stand upon your guard, still watch and pray; and thus ye will be enabled to endure unto the end.”
John Wesley · Explanatory Notes upon the New Testament (on Eph 6:10–18)

Reformed Notable voices

“When our weakness is considered, an exhortation like this would have no effect, unless the Lord were present, and stretched out his hand to render assistance, or rather, unless he supplied us with all the power. Paul therefore adds, in the Lord. As if he had said, You have no right to reply, that you have not the ability; for all that I require of you is, be strong in the Lord. If the Lord aids us by his mighty power, we have no reason to shrink from the combat. God has furnished us with various defensive weapons, provided we do not indolently refuse what is offered. The Lord offers to us arms for repelling every kind of attack.”
