This makes me think... nothing we do is wasted...

Christ has no body but yours,
No hands, no feet on earth but yours,
Yours are the eyes with which he looks
Compassion on this world,
Yours are the feet with which he walks to do good,
Yours are the hands, with which he blesses all the world.


Yours are the hands, yours are the feet,
Yours are the eyes, you are his body.


Christ has no body now but yours,
No hands, no feet on earth but yours,
Yours are the eyes with which he looks 
Compassion on this world. 
Christ has no body now on earth but yours.
