The Titanic, an ocean liner thought to be unsinkable, sank to the bottom of the frigid North Atlantic on April 14, 1912. More than 1500 people died. An iceberg penetrated the starboard side of the ship, destroying the ship's buoyancy, breaking it into two pieces, and sinking it.
Icebergs are formed when large chunks of ice break off from glaciers. They are dangerous because only one-ninth of most icebergs are visible above the surface. Ships can easily sail into icebergs without seeing them.
People are like icebergs. They have damages and disturbances lying below the surface. They look normal, but they are dangerous. Before you make covenant with a friend or a spouse, look carefully below the surface.
