Ephesians 6:10
What does Ephesians 6:10 mean?
Finally, be strong in the Lord, and in the strength of his might.
The short answer
Ephesians 6:10 opens the final section of Paul's letter with a single, urgent instruction: "be strong in the Lord." Notice what Paul does not say. He doesn't tell his readers to be strong in themselves — to summon more willpower, sharpen their arguments, or try harder. The strength he has in mind is borrowed strength. It belongs to God, and believers are invited to draw on it as their own.
The doubled phrasing matters. Paul piles up the words — strength, might — as if one term can't carry the weight. He wants his readers to feel the size of the resource available to them, because he also wants them to feel the size of what they're up against. This verse is the doorway into his famous passage about the armor of God, and it assumes that the Christian life involves genuine conflict, not just private devotion.
It helps to remember who is writing. Paul had spent years in Ephesus itself, and his time there was anything but calm. He had made enemies among tradesmen whose livelihoods depended on idol-making, unsettled the devotees of a great temple, and confronted practitioners of magic. When he later told the Ephesian church to be strong in the Lord, he was writing from hard experience, not theory.
The word "finally" also carries weight. After five chapters describing who believers are in Christ — chosen, forgiven, made alive, brought into one new family — Paul turns to how they will hold their ground. The command flows from everything before it. Because God has already done all this for you, he says in effect, stand in his power now. The verse is less a demand for effort than an invitation to lean your full weight on someone stronger than you.
What scholars say
These two passages from N. T. Wright answer the question behind Paul's command: why would believers need strength beyond their own? Wright describes a church caught in the crossfire of spiritual warfare, sustained by the promise of victory and fresh grace — and points to Paul's own Ephesian enemies, from resentful tradesmen to vengeful magicians, as proof that when Paul wrote these verses he wasn't fooling around.
“Many Christians, for good reasons, like to believe what they are taught and to take it on board with humility and trust, and so are easy prey for those who have subtly different ideas and a clever way of putting them across. But Paul sees that the church is caught in the crossfire of spiritual warfare. It isn’t a matter of simply getting one’s doctrine correct out of a sense of intellectual pride. There is a battle raging for the redemption and renewal of the world and of individual people, and the church is up against the powers of darkness. Paul doesn’t spell this out in detail here the way he does in Ephesians 6.11–20, but verse 20 indicates surely enough that this is how he sees things. What they need is both the assurance that victory will be theirs and the promise and prayer of fresh grace to be with them in every need.”
“This is perhaps the most direct, certainly the most striking, statement of the meaning of Jesus’ crucifixion to be found anywhere in Acts, and it opens up vistas both of the love of God and of the responsibility of the shepherd. The shepherds are therefore to keep watch, because the wolves are prowling around, ready to come and attack. Paul no doubt has Demetrius and his friends in mind, still sore about their loss of business, and indeed the priestesses of Artemis, who may likewise have suffered a decline in attendance at their great temple. There may also be some magicians who didn’t burn their books, and are eager for revenge, to show that their power is after all superior to that of this Jesus. And no doubt many more; when Paul wrote Ephesians 6.10–20, he wasn’t fooling around.”
What it means for you
Most of us don't picture our struggles as a battle, but Paul did — and he wrote this verse for people facing real pressure: opposition, temptation, discouragement, ideas that quietly pull them off course. His counsel is not to grit your teeth harder but to change where your strength comes from. That might mean starting a hard day with honest prayer instead of anxious rehearsal, or facing a conflict asking for God's help rather than trusting your own cleverness. The promise underneath the command is that God's might is actually available — fresh grace for each need, not a one-time deposit you have to make last.
Ephesians 6 in context
Ephesians 6 begins with instructions for households — children and parents, servants and masters — completing Paul's picture of ordinary life reshaped by Christ. Then, at verse 10, the letter pivots to its closing charge. Verses 11–20 describe the armor of God piece by piece: truth, righteousness, readiness, faith, salvation, the word of God, and prayer. Verse 10 is the headline over all of it. Before Paul names a single piece of armor, he names the power source, because the armor is useless without the strength of the one who supplies it.
