Reading the lyrics, I think It's about a baby who is being born. In the bridge, the lyrics read "Pictures replaying of your fragile limbs" After the bridge, the chorus is the same, but with "you" instead of "who" After reading that, I realized that most of the song is probably an allegory, and the final chorus refers to us and God: "You will catch me when the engines fail. You’ll protect me when the train’s derailed. You’ll revive me when my oxygen ceases. You’ll provide me with a new heartbeat."
