Ephesians 3:16 is Paul’s prayer that God would strengthen believers with power through his Spirit, so that the strength reaches the inner person rather than only their circumstances. Paul is praying for the Christians in Ephesus, a church he had not personally founded but cared for deeply. He writes from prison, and his prayer is a request for God’s inner work in ordinary believers.
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…

What Ephesians 3:16 Means
Paul asks God to give his readers something God has in abundance. The phrase “according to the riches of his glory” tells you the scale of the gift. He is not asking for a small trickle of help but for strength that matches the vastness of God’s own glory. The request is that God would do this, which places the initiative with him rather than with the reader’s willpower.
The strength he prays for is “with power through his Spirit.” This is not a call to try harder. It is a prayer that the Holy Spirit would work within the believer to produce a steadiness that does not come from temperament or circumstance. The word “inward” points to the hidden life of the heart, the place where decisions, fears, and hopes take shape.
The verse does not promise that believers will never face hardship, nor that they will feel strong at every moment. It describes a prayer for inner strength that works through the Spirit over time. Paul’s larger letter makes clear that this strength is aimed at growing in love and understanding, not at a sense of invulnerability.
The Context of Ephesians 3:16
Ephesians is traditionally attributed to Paul, written while he was imprisoned, and addressed to a community of Gentile and Jewish believers who had been brought together into one body. In chapter 3 Paul turns from his own suffering, which he calls their glory, to a prayer on their behalf. The verses just before describe him bowing before the Father, and the verses just after pray that Christ would dwell in their hearts through faith.
Because the verse sits inside this prayer, its purpose becomes clearer. The inward strengthening is the foundation for what follows: being rooted in love, grasping the breadth of Christ’s love, and being filled with God’s fullness. Read in this setting, the strength of verse 16 is strength for knowing and loving God more fully, not merely for getting through the day.

A Short Prayer From Ephesians 3:16
Father, you have riches of glory that far exceed anything I could ask or imagine. I ask that you would strengthen me with power through your Spirit, reaching the hidden places of my heart where fear, pride, and weariness often take hold. Make me steady where I am unsteady, patient where I am quick to react, and open where I tend to close myself off. Let your strength be the foundation of my days, so that I can trust you more deeply. Amen.
