Unbeknown Paedobaptist

Was thinking recently (yes, I managed to get round to that) and heres what it was...
What do I think about when I've got nothing to think about? Is my mind occupied with Christ at the times or just some random things... When we dont have the worries of life over hanging us and need not worry about work what do our minds turn to? I know that if you knew what my thoughts turned to it would be embarrasing.
If in this world you are what you eat (with some showing it more than others) then I would say as Christians we are what we think... Therefore (and I speak to myself) what am I? What are we?
