The ashes mean nothing if they don't speak of our mortality (and, of course, the death of Christ and hence the atonement). And so I think these lyrics came to mind because their opening reminds me of what we need to hear--what I, strangely, want to hear--in worship on Ash Wednesday: "You are going to die. And you are going to be judged. And there is a hell. And, yes, this should worry you." Otherwise Easter is just the culmination of our self-realizations, the cuddly affirmation of our own projects.
