I am spiritual....and I do believe in god. I however don't believe I need to be joining a church who have their own man made laws. I do not need to confess my sins to a go between. I believe that I can not be any closer to god then to be out in nature with god. My relationship with god is personal..I do not need outside influence to believe and worship. One of my brothers is atheist and is not spiritual in any respect. I can't see how you can be spiritual if you do not believe in a higher power.

That would end up being an oxymoron. The meaning of atheist means not to believe in the existence of a any Gods or deities. So I doubt you could be spiritual. Look up Atheism. http://en.wikipedia.org/wiki/Atheism

Spirituality is a basic aspect of human development, it deals with the core questions of life... questions like "who am I?", and "what is the meaning of my life?", and "how am I related to the rest of humanity?". Any mature human is likely to be interested in spirituality, simply because it's part of being human. Religions are organized attempts to answer these questions, often with systems of ideas that go together. Religions are structured programs for spiritual development. Most of us want to be wiser, more compassionate, more aware, and have more meaningful lives. Religions try to address these desires. One can certainly work on those matters without joining a formal religion, and many people do -- including Atheists. Unfortunately, religions can also be very divisive. The irony is that the very answers which religions provide to help us become whole are often the hinge-pins of the scissors which cut families, friends, and cultures apart. This happens because people tend to cling too tightly to those answers, and treat non-believers as "the enemy". For this reason, there's often a backlash against religion -- and lots of people who will say "I'm spiritual, but not religious".
