You have searched me, Lord, and you know me.
You know when I sit and when I rise; you perceive my thoughts from afar. 
You discern my going out and my lying down; you are familiar with all my ways. 
Before a word is on my tongue you, Lord, know it completely.
You hem me in behind and before, and you lay your hand upon me. 
Such knowledge is too wonderful for me, too lofty for me to attain.
Where can I go from your Spirit?
Where can I flee from your presence? 
If I go up to the heavens, you are there; if I make my bed in the depths, you are there. 
If I rise on the wings of the dawn, if I settle on the far side of the sea, even there your hand will guide me, your right hand will hold me fast. 
If I say, “Surely the darkness will hide me and the light become night around me,” even the darkness will not be dark to you; the night will shine like the day, for darkness is as light to you.
For you created my inmost being; you knit me together in my mother’s womb.
I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well. 
My frame was not hidden from you when I was made in the secret place, when I was woven together in the depths of the earth.
Your eyes saw my unformed body; all the days ordained for me were written in your book before one of them came to be.

How precious to me are your thoughts,[a] God!
How vast is the sum of them!
Were I to count them, they would outnumber the grains of sand—when I awake, I am still with you.

If only you, God, would slay the wicked!
Away from me, you who are bloodthirsty! They speak of you with evil intent; your adversaries misuse your name. 
Do I not hate those who hate you, Lord, and abhor those who are in rebellion against you? I have nothing but hatred for them; I count them my enemies. 

Search me, God, and know my heart; test me and know my anxious thoughts. 
See if there is any offensive way in me, and lead me in the way everlasting. (Psalm 139)

Psalm 139, authored by David, is designated for Sunday worship. It offers a magnificent portrayal of God, the creator of the universe and the Earth on which we live. God, who is infinite, is also intimate. Not only is He aware of every one of the 8.2 billion people living on Earth, He perfectly knows everything about them, even down to the number of hairs on their heads and the words they will say before they say them. Our lives are an open book to Him. Remarkable! How can God be both infinite and so intimately involved with us? David was captivated by this paradox. 

In these verses, David expresses awe and amazement that God knows every intimate detail of his life. While he doesn't give a detailed exposition of God’s greatness, these twenty-four verses serve as his personal testimony. Although the exact reason David wrote this renowned psalm remains unknown, his message is clear: God is all-knowing, ever-present, and all-powerful. David is wonderstruck that God knows everything about him, is always with him, and precisely created him, even ordaining the number of his days before one came to be.

How might we respond to David’s psalm? To me, the most honest response is one of awe and surrender. Awe for God’s infinite wonder and surrender to His intimate command over my life. One of my longtime favorite worship songs captures these feelings well, and I pray it speaks to you, too.

You are beautiful beyond description
Too marvelous for words
Too wonderful for comprehension
Like nothing ever seen or heard
Who can grasp Your infinite wisdom?
Who can fathom the depth of Your love?
You are beautiful beyond description
Majesty, enthroned above
And I stand, I stand in awe of You
I stand, I stand in awe of You
Holy God, to whom all praise is due
I stand in awe of You.
