Cover art for Fire lyrics by Dead By Sunrise

I couldn't help noticing that this song has many references that could be looked at from christian direction

"No need to see your face or hear your voice To know that you are with me" That COULD mean God Also "When I look to the stars I know just where you are Your looking down upon me" Seems to fit in theme

However I also like lbooqieq's idea of song being "about someone who lost a loved one"

Um, I'm pretty sure this guy doesn't plan on kissing God's lips... haha

So, I too, see it as him going through the death of a loved one.
