Where shall I go from your Spirit?
Or where shall I flee from your presence?
If I ascend to heaven, you are there!
If I make my bed in Sheol, you are there! - Psalm 139:7-8
No matter where you go, God is there. For anything to exist He actively makes it exist so that all He has to do for it to cease to exist is to take His presence from that thing. You truly cannot escape His observation of you.
Not only that, but God knows your thoughts. Every one of them. And even more, He knows your intentions in everything. We don't even know our own intentions a lot of the time.
The difference between the spiritual man and the man who does not have the Spirit is this: One lives with his life shaped by the knowledge that God is everywhere and one does not. If you lived with the knowledge that every evil thought and deed you had was laid bare before God, would you find yourself more actively trying to please Him by avoiding more evil than you do?
