A day was appointed. When the day came, the man arrived to fetch the preacher, and they set off together. On their way there was a little river which had to be crossed. When they reached the bank, the preacher said, "Where is the boat?" "Why do you ask for a boat?" the peasant replied. "The other day you said that when you use that sacred word you can walk on the water. And I was very much astonished to find that it is so. Why take a boat when it is only necessary to say that word?" But the preacher could not do it; he was not a true teacher. So he said to the old man, "You are my teacher. I have spoken, but you have acted; and if I had had your faith I should also have been able to cross the water."
