Paul’s prayer in Ephesians 3 is not casual.
He bows his knees, an act of extraordinary reverence in a culture where prayer was typically offered standing.
What he prays is four-layered petitions, each building on the one before it and pointing toward a single destination.
ESV “…that according to the riches of his glory he may grant you to be strengthened with power through his Spirit in your inner being, so that Christ may dwell in your hearts through faith, that you, being rooted and grounded in love, may have strength to comprehend with all the saints what is the breadth and length and height and depth, and to know the love of Christ that surpasses knowledge, that you may be filled with all the fullness of God.” (Ephesians 3:16–19)
Four petitions. One trajectory: toward the fullness of God Himself.
Petition One: Strength in the Inner Being
Paul’s first request is that God would strengthen the Ephesians “with power through his Spirit in your inner being.”
The phrase “inner being” refers to the regenerated self, the spiritual person shaped by God’s work, not the external life of performance and reputation.
The Greek word for strengthen here is krataioō, meaning to be made mighty, to be rendered strong with a power that is not self-generated.
This is not motivation or discipline.
It is the Holy Spirit reinforcing the believer’s capacity to receive and contain what Paul is about to pray for.
The source is “according to the riches of his glory”: not a measured portion out of God’s wealth, but strength in proportion to how rich God actually is.
Petition Two: Christ Dwelling at Home in the Heart
The second petition follows: “that Christ may dwell in your hearts through faith.”
The word for dwelling is katoikeō (meaning to settle in, to take up permanent residence), not a temporary visit but an occupying presence.
Christ can be present in a person’s life without yet being fully at home in every room.
Paul connects this to being “rooted and grounded in love”: agricultural (roots that anchor) and architectural (a foundation that supports).
The image is stability that enables deeper growth, not the stillness of someone who has stopped growing.
Petition Three: Knowing the Love That Surpasses Knowledge
The third petition is the most paradoxical in the passage.
Paul prays that the Ephesians would “know the love of Christ that surpasses knowledge.”
To know something that surpasses knowledge sounds contradictory. It is not; it describes how love works.
The Greek word for “know” here is ginōskō, which in biblical usage means experiential, relational knowing, not intellectual mastery.
Christ’s love is not fully known by reading about it but by entering into it, experiencing its dimensions as one moves through life with Him.
The four dimensions point in all directions simultaneously; no edge to the love of Christ can be reached by moving in any direction.
Paul says comprehension happens “with all the saints”: Christ’s love is larger than any one person’s experience can contain. Even the sum of all the saints’ encounters still surpasses what knowledge can grasp.
Petition Four: Filled with All the Fullness of God
The fourth and final petition arrives as the destination of everything before it: “that you may be filled with all the fullness of God.”
The phrase “fullness of God” uses the Greek plērōma, a word Paul uses in Colossians to describe the complete divine nature dwelling in Christ (Colossians 1:19; 2:9).
To be filled with God’s fullness does not mean the believer becomes God; it means being filled with all He supplies and imparts.
John 1:16 frames it: “From his fullness we have all received, grace upon grace.”
The four petitions are one movement: inner strengthening makes room for Christ’s full indwelling; that indwelling produces roots in love; those roots give capacity to grasp Christ’s love; grasping that love begins filling the person with God’s fullness.
What This Prayer Expects of You
Paul is not praying for these things as distant theological abstractions.
He is praying for real people in real circumstances, and the implications land in ordinary life.
This prayer exposes the priority of the inner life.
The Ephesians lived in a city famous for commerce, magic, and the cult of Artemis; the pull toward external success was real.
Paul prayed for the inner being first because transformation flows from the inside out.
This prayer reframes what knowing Christ’s love means.
Paul is not content with theological affirmation. He prays that believers would be seized by a love whose dimensions stretch beyond all tracing.
That kind of knowing changes a person.
This prayer sets the highest possible goal.
Filled with all the fullness of God is the most expansive thing Paul could have asked. Verse 20 responds: God can do far more abundantly than all we ask or think. The goal is extravagant; the God who receives it is more than adequate.
Questions Readers Bring to Ephesians 3:16–19
What does “inner being” mean in Ephesians 3:16?
The inner being is the regenerated spiritual self, distinct from the outward life. Paul uses the phrase in 2 Corinthians 4:16, where the inner person is renewed daily as the outer body declines. It is the seat of faith, will, and spiritual receptivity to God’s strengthening.
How can you “know” a love that surpasses knowledge?
The Greek verb ginōskō describes experiential, relational knowing rather than intellectual comprehension. Paul is not asking for conceptual mastery of an infinite subject. He is praying for a deepening personal encounter with Christ’s love that grows over a lifetime, continually exceeding the limits of what reason alone can reach.
What are the “breadth, length, height, and depth” referring to?
Most commentators understand the four dimensions as describing Christ’s love, named in verse 19. They point simultaneously in every direction, conveying that the love has no traceable boundary. No outer limit can be reached by moving outward, upward, downward, or across.
What does “fullness of God” mean?
The Greek plērōma describes the totality of God’s divine nature and grace. Paul uses the same word in Colossians for the fullness of the Godhead dwelling in Christ. Here it describes what God pours into believers: not that they become God, but that they are filled with all He imparts.
Is this prayer only for the Ephesians, or for all believers?
Ephesians is a circular letter, likely intended for multiple churches. The prayer addresses “all the saints” within verse 18 itself, expanding its scope deliberately. Paul’s doxology in verses 20–21 addresses the church across all generations, making clear this prayer carries universal intent for the whole body of Christ.
What is the relationship between the four petitions in the prayer?
They are sequential and cumulative. Inner strengthening (v.16) makes room for Christ’s full indwelling (v.17). That indwelling gives capacity to grasp Christ’s love (v.18). Grasping that love leads toward God’s fullness (v.19). Each petition is a stage in a single movement, not four separate requests.
Praying Ephesians 3:16–19 Back to God
Lord, I am asking for what Paul asked.
Strengthen me in the inner being, not just the outer life.
Let Christ not merely visit but settle in and make Himself fully at home in me.
Root me and ground me in love deep enough to survive what is coming.
Give me the capacity to know a love I can never fully exhaust.
And then fill me: with Your presence, Your character, Your fullness.
I cannot reach this on my own.
I am asking You to grant it according to the riches of Your glory.
Amen.
