A young Christian packing his bag for a journey said to his friend, "I have nearly finished packing; I only have to put in a guide book, a lamp, a mirror, a microscope, a telescope, a volume of fine poetry, a few biographies, a package of old letters, a book of songs, a sword, a hammer, and a set of books I have been studying."

"But you cannot put all that into your bag," objected the friend.
