This song seems to mean that the writer (or Mick) knows his Bible stories, wants salvation, fears judgment but feels like he’ll never change his mind (repent) and will remain a committed sinner. He knows that there is the “Light” and thinks Christ can strike him with it and he’s right. He still has a chance to “awaken” because HE who has begun a good work, in us, will complete it until the day of Jesus Christ, unless we reject salvation (Phillipians 1:16)
