Cover art for You've Got the Love lyrics by Florence + the Machine

Although is does make clear references to God and Christ, it doesn't necessarily have to be a song about them.

The lines where she references either can simply be taking as figures of speech, "Oh Lord, what's the use?" is something many people say when they're frustrated - the first thing that comes out their mouth is, "Oh Lord/Oh God, why?" kinda thing.

The 'Savior' line could be referencing someone who really helped her through a tough time, and they've become the speakers pseudo-savior.

Perhaps it's because I don't believe in God but, my mind immediately goes to this song simply being about someone she cares for deeply, and they've been their person savior at times.
