According to tradition, when the apostle John was bishop in Ephesus, his hobby was raising pigeons. On one occasion an Ephesian elder passed his house as he returned from hunting. When he saw John playing with one of his birds, he gently chided the old bishop for spending his time so frivolously. John looked at his critic's bow and remarked that the string was loosened.
"Yes," said the huntsman, "I also loosen the string of my bow when it's not in use. If it always stayed tight, it would lose its rebounding quality and fail me in the hunt."
"And I," said John, "am now relaxing the bow of my mind so that I may be better able to shoot the arrows of divine truth."
