Personally, I believe in the Bible and its teachings that is where my faith is. I know many people do not agree with my faith but how can those who disagree be sure that they are right about their faith?
That's just it, nobody knows for sure. It's all about one's personal beliefs. For people to use their beliefs as a way of judging others who hold different ones and to declare someone else will be condemned to hell (and I'm not saying you are doing this) is simply misguided and wrong. When you get right down to it nobody really knows, but that ignorance gets papered over by faith.
