Who am I?

I've been pondering this for a while. Is there a central characteristic that defines who I am? Should I be content in not knowing? Should I even care? Whose definition of who I am should I put more weight on? There are a few characteristics I'd like to be known for, but every day the one that takes precedence seems to change. Sometimes I'd like to ask folks what word they'd use if they had to sum me up in a word. But, I'm not sure I really want to know. Sometimes, there is solace in not knowing. I'm sure there are plenty of folks who would sum me up in a word I've never thought of and wouldn't appreciate.

Why should I even care what other folks think of me? Why put any stock in the thoughts of others who are imperfect themselves and only see a piece of me each day? Why not just put my head down and push forward?

As a Christian, shouldn't I only care what I am relative to scripture? Should I comply to scripture as I interpret it? As you interpret it? As my preacher? As your preacher? Wait... Are you Methodist or Episcopal?

I'm not sure what to think...
