Hmm.. I don't think anyone really knows but since brooke fraser is a christian I think it has a lot to do with that. I think its about how she doesn't really know who she is and how she's really a mystery to everyone, including herself, like a code. But its about how God is deciphering her, slowly showing her who she really is and what she can do. Its like he's helping her to see who she is. Even the chorus "oh can you feel the gravity falling, calling us home" its like God is pulling her towards him, away from the earth and showing her what her life really means.
Lol.. ! Just an idea
