Cover art for Now That You're Home lyrics by Manchester Orchestra

Hm. From a very literal sense, it seems like maybe he thought christianity was foolish when he was younger, but now that he's grown, he believes. It's kind of like a born again christian thing - he's been trying to be good and is wondering, now that god is "home," or in his heart, where he belongs, if he'll save him.

That being said, for me, he seems to have a very sarcastic tone throughout the song, like maybe he doesn't really believe in any of this? But maybe that's just his voice and maybe my own beliefs are coming into play and clouding my judgment.
