Can you imagine the story the boy with the five small loaves of bread and the two small fish had to tell for the rest of his life? John made sure that we knew the loaves and fish were small.
That would be a story that the boy could not keep inside for the rest of his life. I bet it dominated everything he did in his life from that moment on.
What story in your life do you have of a miracle Jesus transforming you? What story is so wonderful and so incredible that it just has to come out. Why has it not?
