What makes you nervous?  What is it that you're worrying about the most these days?  The economy?  World events?  A relationship in your own life?
Your own health or the health of a loved one?  It's easy to look around and feel overwhelmed, inadequate and even hopeless.  But these parables give us hope as they tell us of another greater reality that is beyond our human experience.  This is a reality that is at work even now in the midst of our challenging times.
