Wow, what an awesome topic. And a lot of very thoughtful answers. I have never "felt" God in a church. But out on a weekend hike with the Boy Scouts, God surrounded me from every direction. My family are in Northern Arizona, and when I go and visit, I like to take a few hours and go to Sedona and take a short hike. It is such a powerful spiritual area, I feel like I'm glowing when I get back to Mom's house.
I think that Oak and Antiderivitave sum up how I feel pretty well. I'm not really into any one religion, I guess Christian. But this topic has certainly opened my eyes and I may just need to work on the inside.
