You may know that the English word “Courage” comes from the Latin root word “Cor” which means, heart. So, to be courageous, means to “take heart”. I was thinking about this earlier this morning when I read some words in the Bible. As I read them, I found myself reflecting “it takes some courage to pray that”.
This then is about the most courageous prayer you can ever pray. You can find it in the book of Psalms. In Psalm 139 vs. 23 we read;
Search me, O God, and know my heart: test me and know my anxious thoughts
(Psalm139 vs. 23)
In this prayer, the Psalmist does not ask for more blessings, or greater success, or even an easier life. It is a courageous invitation for God to enter the deepest places of our hearts. Many scholars believe Psalm 139 was written by King David. David, was a man who had experienced both profound intimacy with God and the devastating consequences of his own failures, ends this beautiful Psalm with a request: “Search me.”
There are some prayers we pray out of habit, and there are some that really change us.
At first glance, this may seem unnecessary. After all, Psalm 139 has already declared that God knows everything about us. He knows when we sit and when we rise. He perceives our thoughts from afar. Before a word is on our tongue, He knows it completely (Psalm 139:1–4). If God already knows us so completely, why ask Him to search us?
The answer lies not in God’s need to know us, but in our need to know ourselves.
The Illusion Of Knowing Ourselves
Most of us assume we understand our own hearts. We believe we know our motives, our strengths, and even our weaknesses. Yet Scripture paints a different picture. The prophet Jeremiah writes,
The heart is deceitful above all things and beyond cure. Who can understand it?
(Jeremiah 17 vs. 9)
Our hearts have an astonishing ability to hide the truth from us. We justify impatience as passion.
We disguise pride as confidence.
We excuse bitterness as discernment.
We call fear wisdom and self-protection prudence.
We become experts at seeing the faults of others while remaining strangely blind to our own.
That is why David does not say, “I have searched my heart.” Instead, he prays, “Search me, O God.”
Only the One who created the human heart can reveal what lies beneath its surface.
An Invitation, Not An Interrogation
There is something deeply comforting about David’s prayer.
He is not standing before a harsh judge waiting to be condemned. He is opening himself to a loving Father who already knows him completely and yet, loves him still.
Many fear self-examination because they assume they will only discover failure. But God’s purpose is never simply to expose; it is to heal. When God searches us, He is not looking for reasons to reject us. He is uncovering the places where His grace longs to bring healing.
The Grace Of Being Fully Known
Perhaps the greatest wonder of Psalm 139 is this:
God already knows everything David is asking Him to discover.
Every hidden motive.
Every unspoken fear.
Every lingering doubt.
Every secret failure.
And yet He loves him.
The gospel declares an astonishing truth: we are more loved than we ever dared hope.
Nothing we discover about ourselves surprises God. Nothing we confess diminishes His mercy. Nothing we surrender is beyond His power to redeem. This gives us the freedom to be honest.
We no longer need to defend ourselves before God.
We simply need to come.
A Daily Prayer
Imagine beginning every morning with David’s prayer.
“Lord, before I speak today, search my heart.”
“Before I make decisions, search my motives.”
“Before I respond to criticism, search my pride.”
“Before I judge another person, search my own spirit.”
Such a prayer cultivates humility.
It softens our hearts toward correction.
It teaches us to listen more carefully to the Holy Spirit than to our own assumptions.
And slowly, almost imperceptibly, it shapes us into the likeness of Christ.
Living An Examined Life
In the words of Socrates
The unexamined life is not worth living
(Socrates as recorded by Plato in The Apology)
Much of our culture encourages self-expression. “Be true to yourself” is the advice given to many. The gospel encourages self-examination, allow God to show you your true self, so He can transform you.
This is not a call to endless introspection or self-condemnation. It is a call to live openly before the God who knows us completely and loves us perfectly.
The Christian life is not about becoming experts in hiding our flaws. It is about becoming people who trust God’s grace enough to let Him reveal them. For only what is brought into the light can truly be healed.
