I was raised in a family that encouraged me to read and listen and go to church with my friends and see for myself what the different religions offered and then make up my own mind about what I believed or didn't believe. My mother said she was agnostic and had her own ideas about the bible and it being basically a novel based loosely on some history.
I am not bitter at all but maybe that is because I have never believed so I have nothing to be bitter about, I do regularly shake my head in disbelief that others could actually believe such silly things, but I'm not bitter.
As an artist I constantly view my world in awe of the beauty, but I do not question why or how all of this came to be, I honestly do not care.
It "IS" I "AM" and I'm too busy living my live to worry about how and why.
