If I asked you to name a miracle in the Bible, you might say "the ten plagues" or "the parting of the Red Sea" or "the resurrection of Jesus". These miracles are more than just well known miracles, they are moments that shaped history. The ten plagues are remembered every time Passover is celebrated. The parting of the Red Sea was an event that liberated the Israelites and gave birth to a new nation. Easter is the grounds upon which all of Christianity is founded. Even for someone who doesn't believe in miracles, these mysterious and unexplainable events undeniably changed the world.
This story is about a miracle that is no less awesome or deserving, but no one ever thinks of it. Personally, I have never heard it taught in church. It won't be found in an illustrated children's Bible and, while it is printed in every edition of the Bible, most people who read it either skim over it or forget it entirely.
