I go to church every Sunday despite having zero belief in Jesus or God as they describe him. The sermons are socially relevant and thought-provoking, the congregation is caring and fun with cool social events, and the good that they're doing in our community is inspiring.

I encourage HNers to try it! Just mentally replace "God" with "Nature" and "Jesus" with "Me" in every line and you have a good framework for self-reflection and appreciation of the natural world.
