Ephesians 3 Love of Christ: Its Width, Length, Depth, Height
Short answer: The love of Christ in Ephesians 3:14-21 is the settled, self-giving love of God revealed in the gospel, and Paul prays that the Ephesian believers would know it deeply, not merely hear about it. He bows his knees before the Father and asks that they be strengthened in the inner person, that Christ would dwell in their hearts by faith, that they would be rooted and grounded in love, and that together with all the saints they would grasp the width, length, depth, and height of this love. Paul then says this love surpasses knowledge, which is his way of saying no doctrine about it can exhaust it even while real knowledge of it is possible. The prayer ends in doxology: God is able to do abundantly beyond all we ask, and to him be glory in the church and in Christ Jesus.
Paul Kneels Before the Father
The prayer opens with posture. Paul writes in Ephesians 3:14, "For this cause, I bow my knees to the Father of our Lord Jesus Christ". Kneeling was not the ordinary Jewish posture for prayer; standing was. Paul's choice signals intensity and reverence. He is not reciting a form; he is visibly, deliberately humbling himself before God as Father. The phrase begins with For this cause, which ties the prayer back to what he has just written in the earlier part of the letter about Gentiles being brought near and made fellow heirs. The love of Christ is not an abstract idea floating above the letter; it is the reason Paul can pray at all about a divided humanity being joined into one body.
The address matters too. Paul prays to the Father of our Lord Jesus Christ. This is not a vague spiritual power but the Father of the Son he has just been describing. Throughout Ephesians, the whole Trinity is active: the Father plans, the Son accomplishes, the Spirit seals. Paul's prayer language is not an accident of religious vocabulary; it reflects the structure of the gospel itself. He is asking the Father for something only the Father can give. When we pray about our own grasp of Christ's love, this is the right starting point: not self-improvement but petition to the Father of our Lord Jesus Christ, who gives generously to those who ask.
Ephesians 3:15 continues the thought, noting that from the Father every family in heaven and on earth is named. Paul is not making a sociological comment about the word family. He is saying that all fatherhood, every household, every community, derives its very identity from the Father who is the source. To pray to this Father is to pray to the one who establishes belonging itself. If you feel outside of love, outside of community, outside of family, this name is where you begin. The Father of our Lord Jesus Christ is the ground of every true belonging, and Paul kneels to him deliberately. That posture teaches us something about how we should approach our own prayers for a deeper knowledge of the love of Christ.
We should notice as well that Paul does not pray this prayer for himself alone. He says he bows his knees to the Father of our Lord Jesus Christ for the sake of the Ephesian believers. The pastoral heart is on display. Paul has been given a stewardship, as he says earlier in the letter, and his stewardship includes intercession. He cares less that his readers would be theologically impressed than that they would be inwardly strengthened. This is worth keeping in mind when we study the passage. The most famous phrases here, about width and length and depth and height, are not given as a puzzle to solve but as a request made by a pastor on behalf of people he loves.
Strengthened in the Inner Person
The first specific request is found in Ephesians 3:16. Paul asks that the Father would grant them, according to the riches of his glory, to be strengthened with power through his Spirit in the inner person. Note the measure: according to the riches of his glory, not according to the smallness of our need. God's giving is not measured by our capacity but by his abundance. Note the means: through his Spirit. The love of Christ is not understood by the intellect alone or produced by willpower. The Spirit strengthens the inner person so that the truth of the gospel moves from information to formation. Paul is asking for interior strength, not outward brilliance.
The inner person is a phrase Paul uses elsewhere for the seat of life before God, the part of us that is renewed even while the outer self is wearing down. His request is not for improved circumstances but for a strengthened core. This is a crucial corrective. Many people want the love of Christ to fix their anxiety, their loneliness, or their circumstances. Paul wants it to strengthen their inner being so that the outer circumstances do not have the last word. The strength he asks for is not the strength to achieve but the strength to receive. It is the settled capacity to trust, to rest, and to love when nothing in the environment supports it.
There is a pastoral realism in this prayer. Paul does not assume that believers automatically feel the love of Christ. He prays that they would be empowered to know it. Our feelings of being loved ebb and flow, and Paul does not build his prayer on the assumption that everyone in the church at Ephesus was emotionally secure. He builds it on the riches of God's glory and the work of the Spirit. Christians who struggle to feel loved by God are not failures in this prayer; they are the very people this prayer was written for. The strength that Paul asks for is not a substitute for emotion but a foundation under it.
This request also reminds us that we cannot manufacture the knowledge of Christ's love on our own. The same Spirit who raised Jesus from the dead is asked to strengthen us. That means the knowledge is possible, and it also means we should ask for it. We often treat the love of Christ as something already settled, something we simply need to remember. Paul treats it as something to be sought, and to be sought in prayer. Reading this passage correctly includes praying it. The strongest Christian is not the one who never doubts but the one whose inner person has been strengthened by the Spirit to hold fast to what God has said in Christ.
Christ Dwelling in the Heart by Faith
The second request in Ephesians 3:17 is that Christ would dwell in their hearts through faith. This is not a prayer for conversion, as if the Ephesians were not yet believers. Paul is writing to those who already have faith, and yet he prays that Christ would dwell in them. The language is about settled presence, not initial entrance. A guest visits; a resident stays. Paul is asking that Christ would be at home in their hearts, occupying the whole house rather than a single room. The house image is important: it is not merely that Christ is present, but that the heart is his habitation, ordered by his presence.
The phrase through faith tells us how this indwelling is received. Faith is not a mood or an achievement; it is trust in the promises of God. Christ dwells in the heart as faith takes him at his word. This means the Christian life is not a matter of working up an experience but of resting in a person. Paul prays that this resting would become habitual, so that Christ's presence shapes the way a person thinks, feels, and responds. If you want to know the love of Christ more deeply, the pathway Paul lays out is not more information but deeper faith, the daily trust that hands the rooms of the heart over to the one who loved us first.
Notice that the prayer flows directly into the phrase rooted and grounded in love. Ephesians 3:17 continues, being rooted and grounded in love. Two images are stacked: a tree with roots and a building with a foundation. Both speak of stability that comes from what is below, not from what is visible. The love of Christ is meant to be the soil we draw from and the foundation we stand on. This is why Paul cares so much about it. A Christian whose roots are in performance, approval, or circumstances will topple when those things fail. A Christian whose root is the love of Christ can endure because the source is deeper than the weather.
Paul is not describing an elite experience for mature believers only. Rooted and grounded is agricultural and architectural language, and both are about ordinary, unglamorous work. Roots grow slowly. Foundations are laid once and then built on for years. The love of Christ is meant to be the quiet assumption under everything else in the Christian life. When you get bad news, what do you instinctively fall back on? Paul's prayer is that the answer would increasingly be the love of Christ. Not a slogan, but a foundation that holds weight. This root and ground is not a feeling you generate; it is a reality you settle into by faith over time.
Together With All the Saints
Ephesians 3:18 makes a point that is easy to miss. Paul prays that they would be able to comprehend, together with all the saints, what is the width and length and depth and height. The word together matters. The love of Christ is not intended to be grasped by isolated individuals only. It is comprehended in the community of the faithful, where different perspectives, experiences, and gifts fill out a picture none of us could see alone. This is why the church is not optional to the Christian life. If you cut yourself off from the saints, you cut yourself off from one of the God-given means by which the love of Christ is understood.
The dimensions Paul names are almost certainly a poetic way of speaking about the fullness of the love of Christ rather than a mathematical puzzle. Down through Christian history, teachers have offered suggestions: width across the nations, length through all ages, depth into our lowest condition, height to the very throne of God. These are not mutually exclusive readings, and the passage does not settle the question. The point is that no single measure captures the love of Christ. It is vaster than any framework we bring to it, and the community of saints is the place where this vastness is explored over a lifetime of shared worship, teaching, and care.
This corporate dimension has real pastoral weight. If you have been hurt by a church, the call to comprehend the love of Christ together with the saints can sound hollow. But notice that Paul does not romanticise the community. He is writing to a real congregation with real tensions, including the Jew-Gentile divide that runs through the letter. His answer is not to abandon the community but to pray that the community would be the place where Christ's love is known. The church is the household of God, and even an imperfect household is where the Father's name is invoked and the Son's love is taught. Faithful Christians differ on how the gathered church should look, but the New Testament consistently assumes it will be gathered.
There is also a humility built into Paul's prayer here. He asks that they would be able to comprehend, knowing that this is a lifelong pursuit. He never suggests his readers have arrived. If the apostle who wrote the letter still prays this way for churches he planted, then we should not be surprised if our own grasp is partial. The application is not to wait until we feel we understand before we love and serve; it is to keep growing in the knowledge of a love that will always exceed us. The community, the word, the sacraments, and prayer are the means by which this growth happens. Paul's phrase together with all the saints places all of that squarely in the ordinary life of the church.
The Love That Surpasses Knowledge
Ephesians 3:19 expresses what could be called a holy paradox: to know the love of Christ which surpasses knowledge. Paul does not say the love of Christ is unknowable; he says it surpasses knowledge. The point is not that we wander in fog. The point is that this love is not exhausted by any concept we form of it. It is known truly and yet never fully. This is one of the ways the gospel differs from a merely intellectual system. You can master a system. You cannot master a person's love, especially this person's love. The best theology of the love of Christ is true theology, but it is always pointing beyond itself to the one it describes.
Paul joins this knowledge to a goal: that you may be filled with all the fullness of God. This is an extraordinary phrase. It does not mean we become divine; the Bible is careful never to say that. It means we come to share in the life and character that God gives, so that his presence and purposes fill us the way the love of Christ fills the passage. The Christian life is not merely a life of knowing truths about God. It is a life increasingly filled by God himself. And the way Paul describes this filling is tied directly to the knowledge of the love of Christ. Love is the doorway through which the fullness comes.
This is a reason to be suspicious of any teaching that reduces the love of Christ to sentiment. The love Paul describes is not mere warmth or niceness. It is the love of the Son who died for us, as 2 Corinthians 5:14 says, "For the love of Christ constrains us; because we judge thus, that one died for all, therefore all died." Paul's knowledge language is anchored in the cross. To know the love of Christ is to know a crucified love, a love that gave itself up, a love that was not deterred by our unworthiness. That is why it surpasses knowledge. It does not fit into our categories of fair exchange. It is grace, and grace always outruns the ledger.
Paul's longing is that believers would live from this knowledge rather than toward it. When the love of Christ surpasses knowledge, it means we never graduate from needing to hear it again. Every week, every season, every crisis, the same message returns: the Son of God loved me and gave himself for me. Galatians 2:20 puts it personally: "I have been crucified with Christ, and it is no longer I who live, but Christ lives in me. That life which I now live in the flesh, I live by faith in the Son of God, who loved me, and gave himself up for me." The love of Christ is not a doctrine to be filed away. It is a fountain that keeps flowing, and we keep returning to it.
The Doxology That Ends the Prayer
Ephesians 3:20-21 breaks into doxology. Paul writes that God is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us. He does not say God does whatever we ask. He says God is able to do far beyond what we ask. The measure of God's ability is not our imagination but his own power at work in us. This is the fitting conclusion to a prayer that asked for something as large as knowing a love that surpasses knowledge. Paul's confidence is not in the strength of his praying but in the ability of the one he prays to. The prayer is bold because the God is able.
To him be glory in the church and in Christ Jesus to all generations forever and ever. Amen. That is the final line of Ephesians 3 as the passage ends. The glory belongs to God, and the sphere in which it is displayed is the church and Christ Jesus. This is a remarkable pairing. The church, that imperfect gathering of ordinary believers, is named alongside Christ as the place where God's glory is shown. The love of Christ is not merely private comfort; it is public glory. When a community of believers lives out of the love they have received, the praise rises to God. The doxology is not an appendix to the prayer; it is the prayer's destination.
Notice where this leaves the reader. Paul has prayed for strength, indwelling, comprehension, and fullness. He ends by saying God is able. The whole movement is from need to sufficiency, from petition to praise. This is a pattern worth learning. Our prayers for a deeper knowledge of the love of Christ will not be answered because we have framed them well but because God is able. The same God who raised Jesus from the dead and seated him at his right hand is at work in us. If you have ever felt that your grasp of the love of Christ is too weak to matter, Paul's doxology answers it. The power is not in your grasp but in God's ability.
The love of Christ, then, is not a subject to be exhausted in one article or one sermon. Paul's prayer at the end of Ephesians 3 lays out a lifetime's work: strength in the inner person, Christ at home in the heart, roots and a foundation in love, and a growing comprehension of a love that will always exceed our categories. It is meant to be prayed, sung, taught, and lived together with all the saints. And it ends where all true Christian teaching ends, in glory to God in the church and in Christ Jesus to all generations. Amen.
Biblical fidelity check
Ephesians 3:14-21 establishes several things plainly. It establishes that Paul prayed for believers, that the love of Christ is knowable, that this knowledge comes by the Spirit's strengthening and through faith, and that it is grasped together with other Christians. It establishes that Christ's love surpasses knowledge, meaning it is inexhaustible rather than unreal. It establishes the doxology: God is able to do above all we ask or think, and glory belongs to him in the church and in Christ Jesus. What the passage does not establish is that the love of Christ is a general spiritual warmth available without reference to the cross. Paul's whole prayer is anchored to the gospel he has been explaining, the good news of a crucified and risen Lord who has brought near those who were far off.
A common misreading treats the love of Christ as an emotion we must produce in ourselves, and then measures our standing before God by how strongly we feel it. That is wrong for at least two reasons. First, the text calls this love something to be prayed for and strengthened by the Spirit, not something we generate. Second, it locates the love in Christ's own action, not in our feeling, as 2 Corinthians 5:14 makes clear when Paul says one died for all. Feelings are real and often follow the knowledge of the truth, but they are not the foundation. The foundation is the giving of the Son, and that is settled regardless of whether our feelings cooperate on any given day.
Other passages that speak to Ephesians 3:14-21
The theme of Christ's love runs through the whole New Testament, and several complementary passages help fill out Paul's prayer. Romans 8:31-39 answers the fear that our failures might cut us off, asking who shall separate us from the love of Christ and concluding that nothing in all creation can. 2 Corinthians 5:14-15 gives the love of Christ a moral force, the constraining motive for a life no longer lived for self. John 13:1 shows the love of Christ as a real, historical love that continued to the end, expressed in the foot washing and the cross. Galatians 2:20 makes it personal, the Son of God who loved me and gave himself up for me.

Frequently asked questions
What does it mean that the love of Christ surpasses knowledge?
It means the love of Christ is truly known and yet never exhausted by our understanding. Paul prays that believers would know this love and immediately says it surpasses knowledge. The point is not that we cannot know it at all, but that no concept, formula, or explanation can contain it. It is like knowing a person versus solving an equation. You can know someone truly and still be discovering them years later. The love of Christ is the deepest and most inexhaustible reality a Christian ever comes to know, and its depth is precisely why we never stop needing to hear it again.
How do I come to experience the love of Christ more deeply?
Paul's prayer gives us the pattern. First, ask the Father for it, as Paul did on his knees. Second, look to the Spirit, who strengthens the inner person. Third, keep trusting, since Christ dwells in the heart through faith rather than through self-effort. Fourth, stay with the community of saints, because this love is grasped together with others. Fifth, keep returning to the cross, where the love is displayed. Experience usually follows these means over time rather than arriving in a single moment. Faithful Christians differ on how strongly emotions should be expected, but the means are the same.
Is the love of Christ in Ephesians 3 the same as God's love in John 3:16?
Yes, in substance. The love of Christ and the love of God are not two rival loves, because the Son is the one through whom the Father's love is revealed. 1 John 4:9-10 says, "By this God's love was revealed in us, that God has sent his one and only Son into the world that we might live through him." The Father sends, the Son gives, the Spirit applies. When Paul prays to the Father about the love of Christ, he is not setting the two against each other. He is describing one love with one source, one display, and one Spirit-given knowledge. The New Testament treats them as one divine love.
