Ephesians 3:16 is Paul’s prayer that God would strengthen believers with power through his Spirit, so that their inner life grows in strength according to the riches of God’s glory. Paul wrote this as a prayer for the church in Ephesus and the Gentile believers in the wider region, and he prays it while in prison for their sake. The verse shows what he asks God to do for them, and it reveals the source of that strength.
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 begins with the source of the gift: “according to the riches of his glory.” He is saying that God does not give out strength in small, grudging amounts. The generosity of the gift matches the greatness of the giver. When Paul asks God to grant strength, he expects God to act out of his abundant character rather than from a limited supply.
The strength itself comes “through his Spirit” and works in “the inward man.” Paul is not describing physical muscle or a feeling of confidence that comes and goes. He means the hidden center of a person: their thoughts, desires, convictions, and capacity to keep trusting God when outward circumstances press hard. The verse does not promise that hardship will disappear. It promises that God will equip the inner person to stand within hardship.
The Context of Ephesians 3:16
Ephesians was traditionally attributed to Paul, and the letter is usually read as a circular addressed to churches in and around Ephesus. Its opening chapters celebrate what God has done in Christ, bringing Jews and Gentiles together into one body. Chapter 3 is a turning point, where Paul pauses from his teaching to pray for his readers. Just before verse 16, he explains that his suffering in prison is actually for their benefit, which is why he tells them not to lose heart.
Read in that setting, the verse is not a self-help line. It is part of a prayer that moves from strength to love, and then to knowing the fullness of God. The inner strengthening Paul requests is meant to root believers in love so that they can grasp the immensity of Christ’s love. The verse therefore reads as a prayer for stability and endurance that are anchored in relationship with God, not in personal willpower.
Key Phrases in Ephesians 3:16
Philippians 4:13
I can do all things through Christ, who strengthens me.
(WEB)
Paul writes about his ability to endure every circumstance through Christ who strengthens him. Like Ephesians 3:16, this verse locates strength outside the self, in the living presence of Christ. Reading the two together shows that Paul consistently ties endurance to God’s supply rather than personal resolve.
2 Corinthians 12:9
He has said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Most gladly therefore I will rather glory in my weaknesses, that the power of Christ may rest on me.
(WEB)
Here God tells Paul that his grace is sufficient and that power is made perfect in weakness. This pairs well with the Ephesians prayer, because both passages assume that human weakness is the place where God’s strength becomes visible and real.
A Short Prayer From Ephesians 3:16
Father, I come to you today aware of how thin my own strength feels. Thank you that your glory is rich beyond anything I can measure, and that you are willing to give from that abundance. Strengthen my inner life by your Spirit, so that my faith holds when my circumstances shake. Root me in your love, and help me trust that you are working in places I cannot see. Let your power be at work in me today, not because I am strong, but because you are faithful. Amen.
