Ephesians 3:16-21 is Paul’s prayer that Christians would be strengthened by God’s Spirit so that Christ would dwell in their hearts and they would grasp and experience the depth of his love. The passage ends in a doxology, praising God who is able to do far more than we can ask or imagine.
Paul writes this as a prayer from prison in Rome, and it sits at the center of his letter to the churches around Ephesus. Having just explained that Gentiles are fully included in God’s family, he turns from doctrine to heartfelt petition, asking God to deepen the faith of believers he has never met in person.
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 inwardly through the Spirit. The goal is not merely comfort but a settled inner life in which Christ makes his home in their hearts through faith. Paul wants them to be firmly rooted and built up in love.
From there the prayer reaches outward. Paul hopes his readers will grasp, together with all God’s people, how wide, long, high and deep Christ’s love is, a love that goes beyond what can be fully known. He ends by praising God, who is able to act far beyond our requests and imaginations, and he gives that glory to God in the church and in Christ forever.
Context of Ephesians 3:16-21
Ephesians is traditionally attributed to Paul and was written to a community of believers in and around Ephesus, a major city in western Asia Minor. Its central theme is the unity of Jew and Gentile in one body through Christ. Chapters 1 to 3 lay out this theology of grace, and chapters 4 to 6 turn to how believers should live it out.
The verses just before this prayer, in 3:13, have Paul asking his readers not to lose heart over his suffering for their sake. The prayer that follows is his answer: the true source of their strength is not circumstances but God’s power at work within them. Paul’s imprisonment becomes the setting for a prayer about the deepest riches available to every believer.

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 confident list of things that cannot separate believers from God’s love shows the same conviction found in Ephesians 3: that God’s love is secure and reaches further than any threat we face.
Philippians 4:13
I can do all things through Christ, who strengthens me.
(WEB)
Paul’s statement about strength in Christ parallels the Ephesians prayer for inner power through the Spirit, reminding readers that their capacity comes from God rather than from themselves.
A Prayer Based on Ephesians 3:16-21
Father, I ask that you would strengthen me by your Spirit in the inner places of my life, where I am most tired and most afraid. Let Christ make his home in my heart through faith, so that I stop living as a guest in your presence and start living as one who belongs. Root me and ground me in your love.
Help me to grasp, even a little, how wide and deep and high your love is, a love that goes beyond what I can explain. Fill me with your fullness day by day. Thank you that you are able to do far more than I can ask or imagine. Amen.
