I don't relate this song to religion (or any songs for that matter) only because I am not religious, but I can certainly see how this song could be related to God.
To me, it is about a person (any person- a mom, dad, sister, brother, a boyfriend or girlfriend) who is promising to stand by you and give you back that hope and faith in yourself that you've lost (for whatever reason that may be). They're going to be that person for you because you mean the world to them and they can't imagine life without you.
