Now what's the good of two strong legs

If you only run away?
And what use is the finest voice
If you've nothing good to say?

And what good is strength and muscle
If you only push and shove?
And what's the use of two good ears
If you can't hear those you love?
Between those who use their neighbours
And those who use a cane
Between those in constant power
And those in constant pain
Between those who run to evil
And those who cannot run
Tell me which ones are the cripples
And which ones touch the sun?
