The only survivor of a shipwreck was washed up on a small, 
  uninhabited island. He prayed feverishly for God to rescue him,
  and every day he scanned the horizon for help, but none seemed 
  forthcoming.    

      Exhausted, he eventually managed to build a little hut out of  
  driftwood to protect himself from the elements, and to store his
  few possessions.  However one day, after scavenging for food,
  he arrived home to find his little hut in flames, the smoke
  rolling up to the sky.  The worst had happened -everything was
  lost. He was stunned with grief and anger. “God, how could you
  do this to me?” he cried.

      Early the next day, however, he was awakened by the sound 
  of a ship that was approaching the island.  It had come to rescue 
  him. “How did you know I was here?” asked the weary man of his    
  rescuers. “We saw your smoke signal,” they replied.
