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. Psalm 139:7-10

One of the fundamental laws of physics is that nothing can be in two different places at the same time. It is also a fundamental law of physics that no two objects can occupy the same space at the same time. Those truths are so obvious that we just take them for granted.

But how mind-boggling it is to consider those physical laws and think about what David says in these verses from Psalm 139. Although you and I and every other living thing can only be in one place at a time, the LORD himself who created this universe in which we live is not bound by the physical laws he created. At this very moment, God is with you. At the same time he is with some believer on the other side of the world. He is up there on the planet Mars. He is miles beneath the surface of the ocean where the sun never shines. There is no place in all of creation where God himself is not.

We could try to fathom this mystery, but we would fail because it goes beyond our scientific reasoning. It is more important that we see what it means for us to have a God who is present everywhere.

If at any moment God is present at any given place, that means he was there the last time I sinned. Even though I can't see God, he was there and saw exactly what I did. No matter where I go today or what I do, God is already there. He will be an eyewitness of and a firsthand listener to everything I say and do. That's kind of a scary thought, isn't it? What if a parent or a police officer stood beside us 24 hours a day? We'd watch our steps and chose our words a little more closely and we'd be terrified of stepping out of line for fear that we'd get a slap on the wrist--or something more serious--right away. Isn't it even more terrifying to hear that God is everywhere and that I can't escape him, even though my sinful heart would like to get away from him so that I can sin without fear? That's impossible though. We're only kidding ourselves if we think can sin without the LORD being right there to witness the whole thing.

On the other hand, what a relief and a joy it is to know that our God who loves us and gave up his Son to save us is everywhere. Our Savior Jesus who was crucified as punishment for our sins and was raised to life because God forgives our sins is everywhere. That means no matter where I go, my gracious Father loves me and is watching over me. Even up in the highest heavens, David says, God is there. When you're up in the airplane looking down on God's earth, he is there too. If you're crawling through a cave or swimming underwater, God is there. Up or down, north or south, east or west, there is no place and no direction you can go where God is not. He's there to watch over you, to protect you and to see exactly what you're going through. He's there as your gracious, forgiving God who pardons your sins for the sake of our Savior Jesus. No matter where we are or how alone we feel, we are never truly alone. In the LORD we have a God is already everywhere we will ever go.

O LORD, you have searched me 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 know it completely, O LORD. You hem me in—behind and before; you have laid your hand upon me. Such knowledge is too wonderful for me, too lofty for me to attain. (Psalm 139:1-6)

How well do you know your best friend? Or your spouse? Or your children? Even if you do have an excellent relationship with the person to whom you are the closest, there are still things you don't know about him or her. While you might know each other well enough to finish each other's sentences, you can't always be sure what words are about to come out of that person's mouth or what that person is thinking--especially when he or she isn't with you.

But our God does know us that well. He's like a mind-reader. He knows us without limits, as David the psalmist declares in these verses from Psalm 139. Because the LORD knows us completely, the LORD knows even the most minute details about us. He knows when we sit down, when we get out of bed in the morning, where we go and what we do. He knows our thoughts from afar, David tells us. Though we can't see the LORD and he may therefore seem far away, he knows the thoughts going through our minds and hearts and he knows the words which are about to form from those thoughts.

How does it feel to know that God knows your every thought and word even before those thoughts and words have crystallized in the mind and on the tongue?

For us sinners, that's a shameful, even terrifying, concept. If God knows what I'm about to think before I think it, he knows the evil that I'm planning in my heart. He knows if I'm going to think up a way to strike back at someone who hurt me. He knows if I'm going to think indecent thoughts about the lusty images I see on television. He knows that I think there are things I'd love to do more than spend with him in his word. He knows the words I'm about to hurl in anger at my spouse or behind the back of my coworker. God knows all of our thoughts and words before they come into being, and he's not pleased with all of them. Since those thoughts and words are so often laced with evil intent, the LORD as a just God cannot put up with them. Those hidden thoughts and secret words of which we ought to be ashamed will not remain hidden from him because he knows us without limit. And he knows how to give us the unending torment we deserve for such sins.

But for repentant sinners who struggle with sin and guilty consciences, the fact that God knows us so thoroughly is great news! He knows the agony in our hearts as we look back on the sins of our past with regret and remorse. He knows when we wish we had not disobeyed him and when we long for him to have mercy on us. He knows how we want nothing more than to be cleansed of our sins in the blood of Jesus Christ so that we can stand before the LORD and joyfully call him our God.

And what a joy it is to know that our God knows every other thought in our troubled hearts as well! He knows when I lie awake at night, frustrated over the mess that sins have made in my life. He knows my fears about the report I'm going to get from the doctor or about my job which is on the line. He knows how dim the future looks to me as I get older. Not one of my problems or concerns goes unnoticed to my heavenly Father, who knows how to respond to all of them in love and for my eternal good.

The God who reads our minds knew exactly how to deal with our greatest fear--the fear of spending eternity separated from him in hell. God knew what it would take in order to save us from that punishment. And he was willing to pay that price. He punished his Son Jesus for us and took his sinless life as the payment for our sins at the cross of Calvary. Our risen Lord Jesus is now ruling over all things and does everything for our good. In Christ we are holy and blameless before our maker. And now we rejoice to call ourselves children of a heavenly Father who knows everything about us and knows to help us in our troubles.
