This was my comment to a post on Facebook asking "Are there any good arguements for Christianity?" I felt what I wrote sums up my beliefs pretty fully -- both as to how I believe and my thoughts on trying to argue others into believing as I do.
Belief in religion is an emotional thing. Logic does not necessarily enter into the equation. Belief in religion is also intensely personal. That is why you would never see me "evangelising" anyone. I know it gives me comfort, it is intensely interesting to me, and it provides me with a sense of community and peace.
I am probably the world's worst Christian because I recognize that others believe differently and are just as comforted by their belief as I am with mine. I also know, for a fact, that there are folks that are just as comfortable with no organized (or even unorganized) religion in their life.
I also recognize, in my understanding of Christianity, that I am bound to respect their belief (or non-belief) as I ask them to respect mine.
The only thing I can control is my own behaviour, to live a life constantly striving to live up to the belief system I follow. If someone finds that interesting and asks, sure, I'd talk with them about it. Otherwise, I really don't see the idea of trying to argue people into belief as an exercise I want to get into.
