Army of Light

What difference can I make?
 

           The blue tit asked the dove, “What is the weight of a snowflake?”

         " Well, let me tell you a story,” said the blue tit.  “I sat in the branch of a fir tree, and it began to snow. 
           I counted the snowflakes settling on the twigs and needles of my branch.  Their number was exactly 1,274,672
           When the 1,274,673^rd dropped on the branch, ‘nothing more than nothing’ as you say, the branch broke.”

           The dove thought about the story, and then said, “Perhaps there is only one person’s voice lacking in the
           world for peace to come.”
