The only survivor of a shipwreck 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 him from the elements, and to store his few possessions.
But then 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 stung 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.
Remember next time your little hut is burning to the ground, it just may be a smoke signal that summons the grace of God.
"And we know that all things work together for good to them that love God, to them who are the called according to his purpose." (Romans 8:28)
