The Psalmist says it quite palinly in Psalms 139:1-4, 1 For the Chief Musician. A Psalm of David. O Lord, You have searched me and known me.2 You know my sitting down and my rising up;You understand my thought afar off.3 You comprehend my path and my lying down,And are acquainted with all my ways.4 For there is not a word on my tongue,But behold, O Lord, You know it altogether.Psalms 139:1-4 (NKJV)
I think we sometimes, or most of the time forget that God knows everything. He sees everything. How many times have you done things, I know I have, that you wouldn't haven't done if someone was watching, especially if that someone was someone who loved you? It is easy to forget that God is God when it comes what we do especially in "private" as if any of us have privacy with regards to our creator. I just thought it was interesting and something to ponder over.
