Ephesians 3:16-21 is Paul’s prayer for the believers in Ephesus. He asks God to strengthen them inwardly through the Holy Spirit so that Christ may live in their hearts through faith, rooting them in love and filling them with the fullness of God. The passage ends with a doxology, a burst of praise to the God who can do far more than anyone dares to ask.
Paul wrote this while imprisoned, most likely in Rome, and the prayer sits in the middle of a letter about the unity of Jew and Gentile in one church. Chapter 3 is where he explains the mystery God has revealed, and this prayer is the pastoral response to that teaching.
16 That he would grant you, according to the riches of his glory, that you may be strengthened with power through his Spirit in the inward man; 17 that Christ may dwell in your hearts through faith; to the end that you, being rooted and grounded in love, 18 may be strengthened to comprehend with all the saints what is the width and length and height and depth, 19 and to know Christ’s love which surpasses knowledge, that you may be filled with all the fullness of God. 20 Now to him who is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us, 21 to him be the glory in the assembly and in Christ Jesus to all generations forever and ever. Amen.

Ephesians 3:16-21 Summary
Paul begins by asking that God would strengthen his readers with power in their inner being. That strength is not measured by outward circumstances but by the Spirit working within. The goal is that Christ would make his home in their hearts through faith, and that they would be planted and built up in love.
From there the prayer reaches toward a wider knowledge: a grasp, shared with all God’s people, of how wide, long, high and deep Christ’s love is, a love that goes beyond what can be fully known. The prayer aims at being filled with God’s own fullness. Then Paul turns to praise, affirming that the God who acts in believers can do more than they could ask or imagine, and giving him glory in the church and in Christ for all generations.
Context of Ephesians 3:16-21
Ephesians is traditionally attributed to Paul and was written to churches in and around Asia Minor, probably with a general audience of Gentile and Jewish believers in view. In the verses just before this prayer, Paul describes his own suffering as a prisoner for their sake and presents it as something that should bring them honor, not discouragement.
The prayer follows the statement in verses 13-15 that every family in heaven and on earth takes its name from the Father. Paul is praying from that foundation. Because God is the Father of the whole household of faith, Paul bows his knees and asks for blessings that belong to the whole community, not only to one group within it.

In the same way, the Spirit also helps our weaknesses, for we don’t know how to pray as we ought. But the Spirit himself makes intercession for us with groanings which can’t be uttered.

Paul connects the Spirit’s help with human weakness and prayer, showing that God’s Spirit supports believers even when they do not know what to say. This pairs naturally with Ephesians 3, where the Spirit strengthens the inner person.
Colossians 2:7
Rooted and built up in him, and established in the faith, even as you were taught, abounding in it in thanksgiving.

A Prayer Based on Ephesians 3:16-21
Father, I ask that you would strengthen me with power through your Spirit in my inner being. When my strength runs low and my circumstances feel heavy, let your Spirit hold me steady from within. I ask that Christ would make his home in my heart through faith, so that I am not only near him but truly settled in his presence.
Root me and build me up in your love, Lord. Help me to grasp, together with your people, how wide and long and high and deep your love is for us, and let me know that love in ways that go beyond what I can explain. Fill me with your fullness. You are able to do far more than I ask or imagine, so I give you all the glory, in your church and in Christ Jesus, forever. Amen.
