Ephesians 3:18 is Paul’s prayer that Christians would be strengthened enough to grasp, together with all of God’s people, how wide, long, high and deep God’s love in Christ really is. The verse describes love so large that it can only be understood with the help of the whole church.
Paul wrote this to the believers in Ephesus, a city on the western coast of modern Turkey, as part of a longer prayer that runs through the middle of his letter.
May be strengthened to comprehend with all the saints what is the width and length and height and depth…

What Ephesians 3:18 Means
The verse begins with a request that you “may be strengthened.” Paul is not asking for a one-time feeling of confidence. He is praying that God would give you the inner capacity to take in something larger than you could manage on your own. The strengthening is for a purpose, and the purpose is understanding.
The word “comprehend” is about grasping something fully, the way you might wrap your arms around something big. Paul adds “with all the saints,” which makes clear that this kind of understanding is not a solo project. Believers come to see the scope of God’s love together, comparing what each has glimpsed and building a shared picture.
The four dimensions named in the verse, width, length, height and depth, point to love that has no edge you can find. The verse does not explain exactly what each measurement stands for, and it does not promise you will reach a complete grasp in this life. It sets a direction: a love too large to be fully measured, and a prayer that you will keep growing in sight of it.
The Context of Ephesians 3:18
Ephesians is traditionally attributed to Paul, and it was written to a community of mostly Gentile believers who had come to faith in Christ without first becoming Jews. Paul’s main theme is that God has joined people from every background into one body, the church, through Christ. This verse sits inside a prayer that asks God to root these believers in love and to let Christ make his home in their hearts.
Just before verse 18, Paul asks God to strengthen believers with power through his Spirit. Just after it, he says that this love surpasses knowledge, and he closes the prayer with praise to the God who can do far more than we ask or imagine. Read in that setting, the measuring language is not a mathematical puzzle. It is a way of pointing to a love that is secure and that you cannot outgrow.
Key Phrases in Ephesians 3:18
Romans 8:38-39
38 For I am persuaded that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, nor powers, 39 nor height, nor depth, nor any other created thing, will be able to separate us from God’s love, which is in Christ Jesus our Lord.

Paul’s list of things that cannot separate believers from God’s love echoes the sense of boundless love in Ephesians 3:18. Both passages assure you that God’s love is not limited by circumstance, power or distance.
1 John 4:16
We know and have believed the love which God has for us. God is love, and he who remains in love remains in God, and God remains in him.

John links knowing God’s love with living in it. This connects with Paul’s prayer that believers would come to grasp that love more fully, showing that understanding and dwelling in love go hand in hand.
A Short Prayer From Ephesians 3:18
Father, I confess that I often think of your love as small, as something I must earn or keep by my own effort. Strengthen me by your Spirit so that I can receive your love more fully. Help me to see its width, length, height and depth in the ordinary moments of my day. Gather me together with your people, so that we can grow in understanding and encourage one another as we learn what your love is like. Let Christ make his home in my heart through faith. Amen.
