Atheist?

I don't consider myself an atheist and I find It odd to be described by something you don't have rather than what one does have. I do consider myself a very spiritual person but I'm just not very big on the God concept. That also includes that Jesus did not die for my sins. Beyond that I think there's lots to talk about in spirituality but I was just thinking, if I had to summarize it, this kind of clears the air. I have listened to Christian testimonies my entire life. I finally feel like I could give one but it would point more to Buddhist practice than orthodox Christian beliefs.
