I really like the song tiwilight on the other hand I like the book not to crazy about the movie I was one of the first people in pennslvania to read the series and idk but in this song their is a lot of hidden things and we she says as god as my witness I think she is like possible referiing to like holyness and I god probably would agree with someone walking the world with eternal life so I think when she say as good as my witness it has a lot to do with that.
