It's a message of hope and transcendence.
I don't want to go overboard but all of us are seemingly under attack, assaulted on all sides by the horrible things happening all around us, or at least it feels that way sometimes. And this song seems to be saying that even with all that there is a possibility for something else that has real meaning and can get us through.
Maybe it's just lazily written and it wouldn't be the first of his songs you could say that about, but as soon as it begins I'm completely there for all of it. Let's not be so sophisticated that we miss out on something simple and heartfelt.
