Psalm 139

"O Lord, you have searched me and you know me. You 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...For you created my inmost being; you knit me together in my mother's womb. I praise you because I am fearfully and wonderfully mad; your works are wonderful, I know that full well...How precious to me are your thoughts, O God! How vast is the sum of them! Search me, O God, and know my heart; test me and know my anxious thoughts."

Couldn't have said it better myself.
