Child in Time

In this song I didn' t know who are talking to whom. But now it's become clear after thinking of Faust and Mephistopheles. Am I Faust, or Mephistopheles? Or the Lord? And I understand too why they call themselves Deep Purple. Are you the Child or the blind man or one of the bullets or the rochochet? Me? I'd rather be the line.

Sweet Child in time you'll see the line
the line that's drawn between good and bad.
See the blind man he's shooting at the world,
the bullets flying and they're taking toll.

If you've been bad oh lord I bet you have,
and you've not been hit by flying lead.
You'd better close your eyes, bow your head.
Wait for the ricochet, yeah.
