I'm agnostic. I was raised Christian in a Southern Baptist Church. When I was about 12, our pastor was giving a sermon stating that anyone who didn't accept Jesus Christ as their savior would surely go to hell. I had a friend who was Jewish and I knew that in her religion, they believed in David, not Jesus, as the Messiah (who had not come yet). It bugged me. I asked the pastor if even my friend, who was a Jew like Jesus, was going to hell because she did not accept Jesus as her savior. He said yes. I never went back to church again (other than weddings and funerals).
I believe in a higher power, but am not convinced that one religion rules over others. I believe men made religion to control the masses. I think the Bible is a great history book, but it's probably lost a lot in translation over the centuries from the original scrolls. At any rate, it was written by men, so I find the foundation still shaky.
