These are the first lines of the song and it already captures you completely. It is so real about what really involves a person and life. You go through it wanting different things, and since you are little you are led to believe certain things that include religion, facts and science. Then, as years go by, you start making your own beliefs based on experiences. And those can be shattered and transformed from one day to another. But a relationship with someone is different. Even when there is nothing in the world that you believe in anymore, nothing certain, you can always have someone that will provoke faith.
