Cover art for Stay Alive lyrics by José González

The song is about this world now were in darkness in the night everything is rushed this system isn't all that great nothing seems to be right during this time Jesus is with him through this time of darkness till the morning light which is a dawn of a new day the new world I'll do what ever to stay alive is reference to doing what is necessary for salvation to make it to the new day/world there is a truth that is on our side this is what is contained the bible that day is close so open your eyes. There is only one truth in the world are you willing to accept it and do what is necessary to stay alive

I appreciate your interpretation on this song's meaning however, the artist is a known athiest. His album released in 2007 was influenced by the books he read from Richard Dawkins and Peter Singer. He's also in an interview where he talks about this.

In an interview, he talks about how this song was specifically written for The Secret Life of Walter Mitty. The meaning and lyrics were written to fit Walter Mitty's character. If you have seen the movie, you will understand the lyrics.

Cheers!
