God is all-seeing, all-knowing, all-powerful, and everywhere present. God knows us, God is with us, and His greatest gift is to allow us to know Him.

Psalm 139

1 O Lord, you have examined my heart and know everything about me.
2 You know when I sit down or stand up. You know my every thought when far away.
3 You chart the path ahead of me and tell me where to stop and rest.
4 You know what I am going to say even before I say it, Lord.
5 You both precede and follow me.
6 Such knowledge is too wonderful for me, too great for me to know!

"Sometimes we don't let people get to know us completely because we are afraid they will discover something about us that they won't like. But God already knows everything about us, even to the number of hairs on our heads (Matthew 10:30), and still He accepts and loves us. God is with us through every situation, in every trial - protecting, loving, guiding. He knows and loves us completely." ~ Life Application Study Bible commentary for Psalm 139: 1-5
