This is a prayer for a pure heart, a request that God would cleanse the thoughts, desires and motives that you cannot clean up on your own. You can pray it in the morning before the day’s noise begins, at night when regret is replaying in your mind, or in any moment when you sense something in you has gone crooked. Read it aloud exactly as written, or use it as a starting point and speak your own words in the same spirit.
Christian Prayer for a Pure Heart
Father, you see what no one else sees. You know the thoughts I rehearse when I am alone, the envy that rises when someone else gets the thing I wanted, and the small lies I tell to make myself look better. I am tired of living split between what people see and what is true inside me. Create in me a clean heart, Lord, and renew a right spirit within me. I cannot do this by willpower, and I am done pretending that I can.
Search me and know my heart, as David once asked you to do. Show me the places where bitterness has taken root, the desires that have grown larger than they should, and the habits of mind I have excused for too long. Give me the courage to bring them into the light rather than hiding them. Where I have hurt others with my words or my attention, forgive me, and teach me to be honest about what I have done. Guard my eyes, my thoughts and my intentions, so that what I give my attention to shapes me toward you. Make my motives simple: to love you and to love the people you have placed in my life. Amen.
A Shorter Version to Pray in a Moment
Lord, you see my heart right now, and you know where it has wandered. Clean out what is impure, quiet what is restless and turn my desires back toward you. Give me a single focus today, to love you and walk in your truth. I cannot fix myself, so I ask you to do the work I cannot do. Amen.

How to Pray This Prayer
Choose a regular time, such as just after you wake or before you sleep, and pray this prayer at the same point each day. Sit with an open hand on your lap or hold a Bible, since the physical posture can help the words settle in you. If you are struggling with a particular sin, name it once in plain words before you begin, then let the prayer carry that honesty to God.
You might also ask a trusted friend or small group to pray it with you, or to pray for you by name. Confession is easier in community, and a companion can remind you of God’s grace when shame tells you to hide. Return to this prayer on hard days as often as you need, knowing that God does not grow tired of hearing you ask for a clean heart.
A Blessing to Close
May the Lord who searches the heart make your heart whole and steady. May he cleanse what is impure, guard what is tender and fill you with his peace. Go in the confidence that the God who began this good work in you will be faithful to complete it.
