For a while, I was a member of the United Methodist church. I had an experience that made me believe that something that could loosely be described as "God" existed. I decided that it would be a good thing to join a community of other "theists", but which one? I read something that suggested the dominant religion of my own culture was a good choice, because then I didn't have to become familiar with the cultural aspects of other religions. I shopped around a bit and found that the local Methodists weren't too fussy about what I believed, within reason, and so I joined them.
I must say though that I was never totally comfortable describing myself as "Christian" as I couldn't get to a belief in so many of the basics, like resurrection, virgin birth, the Trinity, and so on. Nevertheless I did so for convenience, and the Church didn't seem too worried about it. I decided that the "many roads to heaven" idea was likely correct, though my own version was "one road, many vehicles".
Eventually it all faded away, though I'm still not (quite) an atheist.
