In my life

I was practicing my cello for church. I'm playing "In my life lord be glorified. I remember when that song ment something to me. When I first heard the song I was in college. I wanted so badly to understand God and what he wanted for my life. Now I just wonder if he hears me. I've turned into the christian who walks the walk and talks the talks but doesn't even know if God cares. I've seen people with less standards than my own who get their prayers answered. Why is that so hard for me?
I guess I'll never know.
