The only survivor of a shipwreck was washed up on a small, uninhabited island. He prayed to be rescue, 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.
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 and everything he had was lost. He was stunned with grief and anger. He cried out with anger not understanding how or why this terrible thing had again happened to him.
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.
The lesson is that it is easy to get discouraged when things are going bad. But we need to hang in there and hold on through the tough times - there is usually something good on its way.
