Ephesians 3:16 is Paul’s prayer that God would strengthen Christians from the inside, through his Spirit, so they can live faithfully with power that comes from him and not from themselves. Paul speaks it as part of a prayer he is offering on behalf of the believers in Ephesus, a church he had helped establish and whom he is writing to as a spiritual father.
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
The verse begins with the idea that God gives this strength “according to the riches of his glory.” Paul is saying that God does not hand out strength in small, stingy portions. The amount he gives matches the vast abundance of who he is. Paul is praying that his readers would draw on that unlimited supply rather than trying to manage their faith on their own reserves.
The phrase “strengthened with power through his Spirit” tells us where that strength comes from and how it arrives. The power is not self-generated willpower. It comes through the Holy Spirit, who works within the believer. Paul is not promising that Christians will never feel weak or tired. He is describing an inner resource that God supplies so that faith can endure in real circumstances.
Finally, “in the inward man” points to the place where this strengthening happens: the inner life of the person, the mind, heart, and will, rather than only outward appearance or circumstances. The verse does not promise instant relief from every hardship. It promises that God will reinforce the person from within, so that they can stand firm while they wait for and walk through whatever comes.
The Context of Ephesians 3:16
Ephesians is traditionally attributed to Paul, written while he was in prison, and addressed to Gentile and Jewish believers who together formed one body in Christ. In the chapter before this verse, Paul has been explaining the mystery that God’s plan now includes people from every nation, and he is still in that same thought when he begins this prayer. The worry behind his request is that his readers might lose heart because of his suffering on their behalf.
Read in that setting, the verse is not a stand-alone promise of personal empowerment for any goal a person might choose. It is part of a prayer that the church would be steady, loved, and rooted in God’s purposes, even when its leaders are being tested. The strength Paul asks for is meant to build a community that can comprehend God’s love together and keep walking with him.

A Short Prayer From Ephesians 3:16
Father, you are rich in glory, and I come to you without pretending that my own strength is enough. I feel the weight of what is in front of me, and I ask you to strengthen me in my inner life through your Spirit. Reach the places in my heart and mind where I am tired, afraid, or unsure, and steady them with your power. Help me to trust that what you give is measured by your glory and not by my ability to earn it.
Let your Spirit work quietly within me today, so that I can respond to others and to my circumstances with faith that is real and rooted in you. Strengthen me, Lord, so that I can stand firm and keep walking with you. Amen.
