Fully Known: What Psalm 139 Teaches Us About God's Knowledge, Presence, and Our Value
Most of us are experts at managing what other people see. We know what to show, what to hide, and how to answer the question "how are you doing?" without really answering it. But Psalm 139 takes us somewhere the mirror cannot. It takes us before a God who already sees everything.
David's psalm is deeply personal. He does not simply describe who God is in a general sense. He talks about what God knows about him, God's presence with him, and the God who formed Him. By the end of the psalm, David is no longer just describing God. He is asking God to search his heart and lead His life.
Where Does True Security Come From?
God Knows More About You Than You Realize
Psalm 139 opens with David making a striking acknowledgment. "O Lord, you have searched me and known me." - Psalm 139:1 English Standard Version (ESV)
David is not suggesting that God had to investigate Him because He was missing information. He is trying to describe how complete God's knowledge of Him really is. To help us understand, he lists a few things.
"You know when I sit down and when I rise up; you discern my thoughts from afar." - Psalm 139:2 English Standard Version (ESV)
Sitting down and standing up are things we do hundreds of times a day without thinking about them. That is exactly David's point. Even the ordinary, overlooked moments of life are completely known by God. And then David goes further. God knows His thoughts. Researchers have estimated that the human brain processes somewhere between 6,000 and 60,000 thoughts per day. God knows every single one of them, including the ones we never say out loud.
"Even before a word is on my tongue, behold, O Lord, you know it altogether." - Psalm 139:4 English Standard Version (ESV)
Before David ever speaks, God already knows what is brewing inside of Him. Think about the text message you typed out and deleted. Think about the reaction you had when you saw someone's name on your phone before you picked it up and said hello. Nobody saw those moments. But God did.
Is There Anywhere You Can Go Where God Is Not Present?
After reflecting on how completely God knows Him, David asks a natural question. Is there anywhere he could go where God would not be present?
"If I ascend to heaven, you are there! If I make my bed in Sheol, you are there." - Psalm 139:8 English Standard Version (ESV)
David goes as high as he can and as low as he can. Then he moves horizontally, imagining traveling to the farthest reaches of the sea. And in every direction, God is already there.
"Even there your hand shall lead me, and your right hand shall hold me." - Psalm 139:10 English Standard Version (ESV)
This is where these verses become especially encouraging. There are times in life when we find ourselves in places we never expected to be. And one of the first questions that creeps in is, "Lord, where are you?" David's answer is clear. Even there, God is still present. His hand is still leading. His hand is still holding.
What About the Dark Seasons of Life?
David anticipates that someone might say the issue is not distance but darkness. So he addresses that too.
"Even the darkness is not dark to you; the night is bright as the day, for darkness is as light with you." - Psalm 139:12 English Standard Version (ESV)
There are seasons where life gets dark enough that we cannot see what is coming next. But the darkness that limits our vision does not have the same effect on God. God does not lose sight of us when we cannot see what is in front of us. He still sees you.
Our security is found in God. No matter where we find ourselves, we will never be unknown to Him and never beyond the reach of His hand.
Where Does Human Value Really Come From?
God Knew You Before Anyone Else Did
"For you formed my inward parts; you knitted me together in my mother's womb." - Psalm 139:13 English Standard Version (ESV)
David takes us into one of the most hidden places a human life will ever exist. Before David was a king, before he faced Goliath, before anyone knew his name or what he would accomplish, God was already at work in His life. The picture here is of something being formed piece by piece, like a work of art woven together thread by thread.
And David's response to this is worship.
"I praise you, for I am fearfully and wonderfully made. Wonderful are your works; my soul knows it very well." - Psalm 139:14 English Standard Version (ESV)
Notice where his attention goes. He does not say, "I am magnificent." He looks at the life God has made and says, "Wonderful are your works." He redirects all of it back to God.
Does Your Value Depend on What You Can Do?
We live in a world that measures value by contribution, success, money, and usefulness. The problem is that none of those things are permanent. Strength can disappear. Health can change. A career can end. An injury can take away what your body used to allow you to do. If our value comes from those places, then someone, somewhere, has the power to determine our worth.
But that is not what Psalm 139 says.
Our value begins with God. It begins before any accomplishment. It begins before any independence. It begins before anyone else can decide what we might contribute. That means the child developing in the womb already has value because God was involved. It means the person living with a disability has no less dignity. It means the elderly man or woman who now needs help with daily tasks has not lost the thing that made their life valuable in the first place.
"Your eyes saw my unformed substance; in your book were written, every one of them, the days that were formed for me, when as yet there was none of them." - Psalm 139:16 English Standard Version (ESV)
David's life was never a surprise to God. His life was known before he ever lived one day of it. God made that determination before anybody else got a vote.
"How precious to me are your thoughts, O God! How vast is the sum of them! If I would count them, they are more than the sand. I awake and I am still with you." - Psalm 139:17-18 English Standard Version (ESV)
You cannot count God's thoughts about you. There are too many. And after everything David has considered, he lands on this simple recognition. God is still with me. Even knowing everything about me, He is still with me.
What Does It Mean to Say Your Life Belongs to God?
David Draws a Line of Allegiance
In verses 19 through 22, David uses some strong language about those who set themselves against God. This can sound jarring at first, but it is important to understand what David is actually saying. He is not expressing personal bitterness toward people he dislikes. He is describing people who have openly set themselves against the God He has just spent 18 verses worshiping.
When David says he hates them, it is not the same definition we use today. It is a complete rejection of their allegiance. David is drawing a line and saying, if they have set themselves against you, Lord, I will not join them. My life belongs to you.
Why Did David Then Turn the Examination Back on Himself?
After making that strong declaration, David does something remarkable. He points it back at himself.
"Search me, O God, and know my heart! Try me and know my thoughts! And see if there be any grievous way in me, and lead me in the way everlasting!" - Psalm 139:23-24 English Standard Version (ESV)
The word "search" here is the same word used in verse one. God had searched David. Now David is asking for it. He is inviting the examination.
It is possible to take a right stand for something and still have the wrong Spirit while doing it. You can be right about someone else's sin and still turn prideful toward them. You can oppose something that dishonors God and allow bitterness to take root in your own heart. You can say you are standing on truth, but somewhere along the way it stops being about truth and starts being about winning an argument.
David has just made one of the strongest declarations of loyalty in the entire psalm, and then immediately says, God, test my thoughts. Make sure what is happening inside of me matches the loyalty I am claiming with my mouth.
If our lives belong to God, then He has the right to examine them. He has the right to correct our motives, expose what does not belong, and lead us away from it.
How Does Psalm 139 Point Us to Jesus?
Being fully known by a holy God would be terrifying if that were the whole story. God knows our sin. He knows every time we have chosen our way over His. He knows the motives we hid from everyone else.
But the Gospel tells us that God already knows the full truth about us, and He sent His Son to save us from that truth. Jesus Christ lived the righteous life we have failed to live. He went to the cross and bore the judgment our sin deserved. He was buried, and on the third day He rose again. The sinner who comes before Him in full repentance can be fully forgiven and fully known.
You do not have to convince God that your life is put together. He already knows every bit of it. And because of Jesus Christ, we have the opportunity to rest in the truth that our security is found in God, our value begins with God, and our lives belong to God.
Life Application
This week, take a few quiet minutes and pray David's prayer from verse 23. Ask God to search your heart and reveal anything that needs to change. This is not a comfortable prayer. What He reveals may be difficult to face. But the goal is not to feel bad about yourself. The goal is to let Him lead you away from whatever is not right and toward the way everlasting.
Consider these questions as you reflect:
Are there thoughts, motives, or attitudes you have been keeping hidden that you know God already sees?
Is there an area of your life where you have been finding your security or your value in something other than God?
Is there a place in your life right now, a dark season or a difficult circumstance, where you need to be reminded that God is still there and His hand is still leading you?
Are you willing to invite God's examination, not just of your actions, but of the motives behind them?
You are fully known by God. That is not a threat. Because of Jesus, it is the greatest comfort available to you.
