Ephesians 3:16-21 is Paul’s prayer for the believers in Ephesus, asking that they would be strengthened by God’s Spirit, rooted in love, and filled with the fullness of God. It ends with a doxology that praises God for being able to do far more than anything we ask or imagine.
Paul wrote this as part of a longer prayer in the middle of his letter, after he has explained that Jewish and Gentile believers now belong together in one body through Christ. The prayer shows what he hopes will follow from that unity: a community that is secure, loved, and growing in knowledge of God.
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 God to strengthen his readers with power through the Spirit, working in their inner lives rather than only in outward circumstances. He then hopes that Christ will settle in their hearts through faith, so that they stand on love as a firm foundation.
From there the prayer reaches toward the vastness of Christ’s love, which Paul says is greater than anyone can fully grasp, and asks that his readers be filled with God’s fullness. He closes by praising God, who is able to do far more than we dare to ask or picture, and gives him glory in the church and in Christ across all generations.
Context of Ephesians 3:16-21
Ephesians is traditionally attributed to Paul, written while he was in prison, and addressed to a community of believers in and around Ephesus. Many scholars note that some early manuscripts omit “in Ephesus” from the opening verse, so the letter may have been a circular intended for several churches.
In the verses just before this passage, Paul explains that he suffers for the sake of these believers and that their faith is part of God’s wider plan to reveal his wisdom through the church. The prayer therefore grows out of a pastoral concern: Paul wants his readers to stay steady, secure, and united as they face opposition.
