Derek Webb (formerly of Caedmon's Call, now with a solo career) has a song that is very relevant to this thread. I also happen to love it!

"A King & A Kingdom" lyrics are below:
(vs. 1)
who's your brother, who's your sister
you just walked passed him
i think you missed her
as we're all migrating to the place where our father lives
'cause we married in to a family of immigrants
(chorus)
my first allegiance is not to a flag, a country, or a man
my first allegiance is not to democracy or blood
it's to a king & a kingdom
(vs. 2)
there are two great lies that i’ve heard:
“the day you eat of the fruit of that tree, you will not surely die”
and that Jesus Christ was a white, middle-class republican
and if you wanna be saved you have to learn to be like Him
(chorus)
(bridge)
but nothing unifies like a common enemy
and we’ve got one, sure as hell
but he may be living in your house
he may be raising up your kids
he may be sleeping with your wife
oh no, he may not look like you think
I've become a big Derek Webb fan - he really seems to pour his heart and soul into his ministry of music. I saw him in concert on my birthday this past February and he told the audience that he feels that it is his job to tell the truth, regardless, through his music. Because of this, he has some very interesting, thought-provoking lyrics. If you don't already know his music, I would encourage you to check him out!
