While I do believe in a God - although that is a relatively recent development, and arose from spending almost a quarter of my life so far in introspection on the matter - I am utterly unsure what form that takes. I am a member of no organised religion, and don't even have a clear idea of what I think of the God I have so recently found, or what I believe of him. I don't know if I believe in even basics tenets of most faiths, like heaven or hell, or that He actually loves us. I simply believe He exists in one form or another, and I do believe he directly influences the world in certain ways. I do pray relatively frequently.
I have many qualms about "organised" religion, and many of these have been cited in this thread. I am not keen on the influence various Churches have in politics and economics, and strongly believe these things should be kept separate.
Furthermore, I believe one's faith should be personal and individual, not simply adhering to something you would otherwise think wrong simply because it is written in the Bible. I, for one, am bisexual, and so I'm not going to adhere to the belief that being LGBT is a sin. I also support abortion, contraception, and many other things that are prohibited in various faiths. Prayer, as well, should be personalised - the words should be your own, from the mind God created for you, tailored to your deepest wants, fears, and emotions. I find things like mass-prayer defeat this.
I'm still developing my fledgling faith, however, and my opinions and belief are always open to change. I'll never be close-minded enough to disregard challenges to my beliefs, from any source, or I certainly hope not. I'm also not going to be disdainful to anyone for their beliefs unless they are harmful to others, and I'm definitely not going to try converting people when I'm not still entirely sure of my faith myself, and I wouldn't attempt to anyway - it is their right to decide for themselves.
How did I come to these conclusions? As I said above, a great deal of introspection. I've only recently turned 16, and I've been deliberating on this issue in earnest since I was about 11 or 12 years old. In the end, it was not logic or reasoning that led me to my -admittedly still fairly weak - faith, and no rationalisation was made. I simply came to the decision that I believed in a God. I was asked, one day, whether I did, and almost surprised myself by simply saying "yes" rather than saying I was not sure. That was really the key moment when I accepted that I did believe, for whatever reason.
In developing my faith, I have had an individual who is very close to me to guide and advise me. They've helped me in my understanding of the Christian faith - their own religion - and helped me to delve into my own moral values and beliefs, what I think of God, and so on and so forth. This development is ongoing, and I imagine it will be many, many years before I choose any definite religion for myself, and finalise my concepts of God, the Bible, and my views on the whole situation.
On the side-topic of evolution: I believe firmly in evolution. Whether God created original life or not, I believe that we have evolved naturally throughout millennia to become what we are today, as have other species.
Oh, my word, that is rather ineloquent and rambling, and doesn't convey everything I mean to say completely. I may well edit that later on.
