Welcome to our 365-Day Journey to Discover God!
Have you ever had so much on your mind that you didn't know how to explain what you were feeling?
Sometimes we feel deeply hurt but tell people, "I'm fine." Sometimes we're worried about something but can't find the words to describe it. Even the family members and friends who know us best may not fully understand what's going on inside.
We all want to be understood, but human understanding has its limits. People can see our expressions and hear what we say, yet they can't always know the thoughts and feelings we keep to ourselves.
Today, we're going to read a remarkable passage from Psalm 139. In this psalm, David describes a God who knows not only what he says but also what he thinks, how he lives, and even the words he hasn't spoken yet.
If such a God really exists, what would it mean to be completely known by Him?
Psalms is a collection of 150 songs and poems in the Old Testament. These writings express people's praise, gratitude, questions, and prayers as they experience different seasons of life.
On Day 2, we read Psalm 19, where David looked up at the heavens and reflected on the glory of the Creator through the beauty of the sky and the sun.
Today, we turn to Psalm 139, another psalm attributed to David. But instead of focusing on the vast universe, this poem turns our attention inward—to the thoughts, feelings, and experiences of one human being.
Throughout Psalm 139, David describes what he believes about God: God knows everything about him, is present wherever he goes, and has been involved in his life from its very beginning.
The first six verses focus on one important aspect of God's character: God knows everything.
In Christian theology, this is called omniscience. It means that God's knowledge is not limited in the way human knowledge is. According to the Bible, God knows not only what happens outwardly but also people's thoughts, intentions, and feelings.
If you're new to the Bible, this may be a surprising idea. For now, let's explore how David describes it and consider what it might mean.
Earlier in our journey, Genesis introduced us to the God whom the Bible describes as the Creator of heaven and earth. In Psalm 19, we explored how David saw the beauty and order of nature as a reflection of God's glory.
These passages began to introduce us to the Bible's understanding of God—not only as the Creator of the universe but also as someone people can seek to know.
But this raises another question: If God really exists, is He concerned only with the universe as a whole, or does He also know the details of individual human lives?
There are billions of people in the world, each with their own experiences, worries, and hopes. We might wonder: Even if there is a God who created everything, would He notice someone as ordinary as me?
Psalm 139 invites us to explore that very question.
Think for a moment about the person who knows you best.
Maybe it's a parent, your spouse, a close friend, or someone you've shared many years of life with. They may know your habits, your preferences, and even recognize when something is wrong just by looking at your face.
But even that person cannot know every thought that passes through your mind.
Some things we choose not to share. Other feelings are so complicated that we struggle to explain them, even to ourselves. Sometimes we make decisions without fully understanding our own reasons until much later.
Understanding another person takes time, communication, and trust. And even then, there are limits.
But Psalm 139 describes God very differently.
David says that God knows when he sits down and when he gets up. God understands his thoughts, knows his daily activities, and is aware of his words even before he speaks them.
That idea may feel comforting, but it might also make us a little uncomfortable.
If someone knew everything about us—including the things we would rather keep hidden—would we feel safe, or would we feel exposed?
Let's keep that question in mind as we read today's passage.
1. God Knows Our Thoughts — Even the Ones We Never Share
Psalm 139:2 says:
"Thou knowest my downsitting and mine uprising, thou understandest my thought afar off."
David believes that God sees more than his outward actions. God understands what is happening in his mind.
We usually get to know people through what they say and do. But outward behavior doesn't always reveal what's going on inside. Someone may appear strong while feeling deeply vulnerable. Someone else may seem calm while struggling with fear or uncertainty.
According to David, God's understanding goes beyond what people can see.
This is one meaning of God's omniscience: He doesn't have to guess what someone is thinking or slowly discover who they are through observation.
If you're exploring whether God exists, here's something worth considering: If there really is a God who understands my thoughts completely, how might that change the way I think about Him?
2. God Knows Our Daily Lives — Even the Ordinary Moments
Verse 3 says:
"Thou compassest my path and my lying down, and art acquainted with all my ways."
The references to walking and lying down describe ordinary parts of everyday life. Whether David is going somewhere or resting, he believes God knows what he is doing.
What's interesting is that this verse doesn't describe a great achievement or an extraordinary event. It describes ordinary life.
We wake up, go to work or school, eat meals, return home, and rest. Most of these moments don't seem especially important.
Yet David believes that God's knowledge of a person isn't limited to major events.
In the Bible's picture of God, a person's life doesn't matter only when they accomplish something impressive or receive recognition from others. Even the quiet, ordinary moments are known to Him.
3. God Knows Our Words — Even Before We Speak
Verse 4 says:
"For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether."
Sometimes the words we speak don't fully express what we mean.
We might say the wrong thing because we're nervous, remain silent because we're afraid, or speak harshly in a moment of frustration and regret it later.
Misunderstandings are common in human relationships. But David believes that God knows him more deeply than words alone can express.
In verse 5, David continues:
"Thou hast beset me behind and before, and laid thine hand upon me."
Within the larger context of the psalm, David doesn't describe God's complete knowledge merely as something frightening. He also sees God's closeness as something extraordinary.
In verse 6, he responds with amazement:
"Such knowledge is too wonderful for me; it is high, I cannot attain unto it."
For David, being fully known by God is something profound and beyond his ability to comprehend.
Psalm 139:1–6 (King James Version)
1 O LORD, thou hast searched me, and known me.
2 Thou knowest my downsitting and mine uprising, thou understandest my thought afar off.
3 Thou compassest my path and my lying down, and art acquainted with all my ways.
4 For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether.
5 Thou hast beset me behind and before, and laid thine hand upon me.
6 Such knowledge is too wonderful for me; it is high, I cannot attain unto it.
"O LORD, thou hast searched me, and known me." — Psalm 139:1 (KJV)
In just a few words, David expresses something central to his understanding of God: God isn't merely a distant Creator somewhere beyond the universe. He knows individual human lives.
If you're not sure whether God exists, consider this question: If there really is a God who knows me this well, what would I want Him to understand about my life?
We all want to be understood. But sometimes we're also afraid of being known too well.
We're often happy to share our strengths, achievements, and joyful experiences. But we may be less willing to let others see our failures, weaknesses, and thoughts we're not proud of.
Why?
Because somewhere inside, we may wonder: If people knew what I was really like, would they still accept me?
That fear can lead us to hide parts of ourselves.
We try to appear strong, independent, and dependable, even when we're exhausted or struggling.
Psalm 139 describes a very different kind of relationship.
David believes that God knows everything about him. God doesn't need David to explain his circumstances or rely on other people to tell Him what's happening.
What's especially interesting is David's response.
He doesn't react with despair. Instead, he expresses wonder.
He recognizes that God's knowledge is far beyond anything he can fully understand.
Of course, if you're not sure you believe in God, this description may raise new questions. Why would God know everything about us? What does He think about our mistakes? If He understands our pain, why do we sometimes feel so alone?
These are important questions, and the Bible doesn't expect us to understand every aspect of God's character after reading just six verses.
But today, we can consider one possibility:
If there really is a God who knows not only my strengths but also my weaknesses, fears, and unspoken thoughts, would I be willing to learn more about Him?
Perhaps discovering God isn't only about finding out whether someone created the universe. It may also involve exploring whether that Creator truly knows and cares about us.
Questions to Think About
Have you ever wanted someone to understand you but struggled to explain what you were feeling? What did you most wish they could understand?
When you read that God knows your thoughts and everything you do, how does that make you feel—comforted, curious, uneasy, skeptical, or something else? Why?
If there really is a God who understands you completely, what is one thing about your life that you would most want Him to know?
Today's Small Action
Find a quiet moment today and spend three to five minutes paying attention to what's on your mind.
You don't need to analyze everything or decide whether your feelings are right or wrong.
You might write down one sentence:
"Something I've been wanting to say but haven't found the words for is..."
It could be a worry, a hope, a regret, or a question you haven't been able to answer.
If you feel comfortable, you might also imagine sharing that thought with the God described in today's passage and notice how that experience feels.
Today, David tells us that God knows our thoughts, our words, and even the feelings we haven't shared with anyone. If you'd like, you can try telling God what's really on your heart. You don't need special words. Just speak naturally, as you would to a friend who's willing to listen.
Let's pray together:
God, Creator of heaven and earth, thank You for giving me the opportunity to read Psalm 139:1–6 today. David says that You know when he sits down and when he gets up, and that You understand his thoughts. I find that amazing because sometimes I don't even fully understand what's going on inside my own heart. If You really know me that well, I wonder what You see when You look at me.
There are things I keep to myself—worries, weaknesses, and questions I haven't found answers to. If You already know all of this, I hope I don't have to pretend to be strong or hide how I truly feel when I talk to You. I'm still not sure what it means to know You, but I'm willing to keep exploring what the Bible says about You.
If You truly know me and care about my life, please help me come to know You, little by little. As I continue this journey, I hope to discover more than just facts about You. I want to understand whether it's really possible to have a personal relationship with You.
In the name of Jesus Christ, I pray. Amen.
Today, Psalm 139 introduced us to a God who, according to the Bible, knows our thoughts, words, and everyday lives.
This leaves us with another question worth considering:
If God truly knows us completely, is it also possible for us to come to know Him?
As we continue this journey, may we not only gather information about God but also explore what the Bible says about His relationship with human life.
