Looking at what @saatwik and @AlmightyChrissy wrote I'm only slightly less confused by this song. I think both are on to something though. It's as though they've both gotten in way over their head with something and as a last result have turned to prayer. Towards the end when he hear's Where's your halo? It's as though he is trying to blame the other for all their problems and is being told you're not perfect, you're as much to blame as she is.
