Mike, over at Waving or Drowning, posts a wonderful Franciscan Benediction:
May God bless you with discomfort
At easy answers, half-truths, and superficial relationships
So that you may live deep within your heart.
May God bless you with anger
At injustice, oppression, and exploitation of people,
So that you may work for justice, freedom and peace.
May God bless you with tears
To shed for those who suffer pain, rejection, hunger and war,
So that you may reach out your hand to comfort them and
To turn their pain into joy.
And may God bless you with enough foolishness
To believe that you can make a difference in the world.
So that you can do what others claim cannot be done
To bring justice and kindness to all our children and the poor.
