External circumstances change. Jobs are lost. Health fails. Relationships fracture. The world around us is constantly shifting. What sustains us through all of it is not external stability — it is the deep, settled fortitude of the inner person. This is inner strength. And only God can build it.
There is a kind of strength that runs out when circumstances get hard enough. It is the strength of willpower, of determination, of self-generated resilience. Most self-help books are about developing this kind of strength. And it has genuine value — up to a point. But it has a ceiling. Push any person hard enough, for long enough, in enough areas simultaneously, and self-generated strength collapses.
There is another kind of strength that does not have a ceiling. It is the strength Paul prays for in Ephesians 3:16 — being "strengthened with power through his Spirit in your inner being." This is inner strength in the deepest biblical sense: not the fortification of the outer person but the fortification of the inner person. Not the strengthening of the will but the strengthening of the soul. And its source is not human effort but divine supply.
This page is devoted to praying for that deeper strength. It is part of our complete guide to prayer for strength and connects closely with our pages on prayer for strength in difficult times and prayer for strength and peace.
"I pray that out of his glorious riches he may strengthen you with power through his Spirit in your inner being, so that Christ may dwell in your hearts through faith. And I pray that you, being rooted and established in love, may have power, together with all the Lord's holy people, to grasp how wide and long and high and deep is the love of Christ."
Ephesians 3:16-18 (NIV)
This is one of the most breathtaking intercessory prayers in all of Scripture. Paul prays for strength in the inner being — the deepest part of the person where character, faith, and love reside. The mechanism of this strength is the Holy Spirit working from within. The result is not just personal stability but an expanding capacity to grasp the dimensions of God's love — which is itself a source of strength. Knowing how loved you are is fortifying. It makes you immovable.
Heavenly Father, I come before You asking not for a change in my circumstances but for a change in my interior. I am asking for inner strength — the kind that Shadrach, Meshach, and Abednego had when they stood before the furnace, the kind that Paul had when he sang in prison, the kind that Job had when everything external had been stripped away and he still said "my Redeemer lives."
Lord, strengthen me in my inner being, as Paul prayed for the Ephesians. Let Your Spirit work from the inside out — fortifying my soul before the challenges of the day reach it. Build in me a rootedness in Your love that does not shift when circumstances shift. Let Christ dwell in my heart through faith — not as a guest but as the permanent resident who rearranges the furniture and makes the place His home.
Give me the settled peace that comes not from resolved circumstances but from a resolved relationship with You. Help me to know, at the level of my bones rather than just my theology, that I am loved by You with a love that is wide and long and high and deep — a love that has no edge I can fall off. Let that knowing be the anchor of my soul.
Build endurance in me, Father. The kind that James describes — the product of faith tested by trial. I do not ask for easy circumstances. I ask for the character that difficult circumstances produce in a person who keeps turning to You. Let perseverance finish its work in me. Let me be complete, lacking nothing in the things that actually matter. In Jesus's name, Amen.
Lord, strengthen me in my inner being by Your Spirit. Root me in Your love. Let nothing shake what is grounded in You. Amen.
Father, build in me an inner fortitude that does not depend on outer circumstances. Let Christ dwell deeply in my heart. Amen.
God, when everything around me shakes, let what is inside me hold. Be my deep foundation. Amen.
It is what Paul describes in Ephesians 3:16 — being "strengthened with power through his Spirit in your inner being." It is deep, settled fortitude of the soul that allows a person to remain stable even when external circumstances are chaotic. See our complete guide for the full picture.
Through consistent Scripture, persistent prayer, enduring difficulties with faith, and deep community. Trials produce endurance (James 1:3-4). Paul "learned" contentment through experience. Our prayer for strength in difficult times addresses this growth process directly.
Willpower is self-generated and runs out at the edge of human capacity. Biblical inner strength is God-generated through the Spirit and has no such ceiling. See our scripture prayers for strength for the passages that describe this divine supply most clearly.
