10 points for best answer! Any help is appreciated!(although that probably won't make you answer my question)

So, I go to a Christian school and have been a Christian for a long time. I have started reading on other religions when I came to realize why I was a Christian. We grow up like this. This is the only thing we are tought. We learn not to question these things. But what about other religions? This really poses a problem. All religions have faults, but while you believe in one you are afraid of the teachings of the others. If this makes any sense at all to you I would like to know what you think about religion. I know that there is a God, but I am still confused about religions. Any advice?
