I was on the plane, returning from ministry in Belfast, Northern Ireland when I heard the fascinating story. Danielle, the woman next to me, has deep roots in Northern Ireland. We got to talking about the Titanic, which was built in Belfast. That's when she told me about her great-grandfather. He was a professional seaman - and he had been assigned to sail on the Titanic. But at the last minute, his orders were changed - to sail instead on the Carpathia, the ship that was first on the scene of the Titanic's sinking - actually the ship that rescued the survivors from the icy waters of the Atlantic.
