I´m not the king

I´m not the king
The king of rock, some say lives
The lizard king is surely dead
The king of France lost his head
The King of Kings bled
I'm not the King I just sing yeah
I'm just a fraction of a thing yeah
I am not anything without the King of Kings
If I were King I'd be unwise
For my brains aren't Kingdom size
A King's someone to trust and love
Like Jesus Christ whom I sing of
