In a great hot land far away, in the shade of a great tree, there slept a lion.
A small mouse, who was running across the grass without looking very carefully, ran straight onto the lion's paw, and then up the lion's back, and then onto the lion's nose.
The lion woke up. He caught the mouse in one paw. He held the mouse very gently, the way lions can, when they choose to.
"Please," said the mouse. He was shaking. "Please do not eat me. I am very small. I would not even be a proper mouthful. And someday, perhaps, I could do something for you in return."
The lion laughed. He laughed for a long time.
"You?" he said. "Do something for me? You are the size of my smallest claw. What could you possibly do for a lion?"
But the lion was a kind lion, on the whole. And he was not very hungry. So he opened his paw, and the mouse went away, very quickly, in the direction of home.
A long time later, on a different day, the lion was walking through the wood when he stepped into a hunter's trap. A great rope net came down from the tree. The lion was caught. He thrashed and roared and tried to bite the ropes. The ropes did not break. The hunters were coming.
The mouse heard the lion roaring. He came running through the grass.
"Hold still," said the mouse.
He began to chew. He chewed at one rope. He chewed at another. His small sharp teeth went through the ropes the way the lion's great teeth could not. One rope. Two ropes. Three.
The lion was free.
He looked down at the mouse. The mouse looked up at the lion.
"I told you," said the mouse, "that someday, perhaps, I could do something for you in return."
The lion did not laugh this time. He bowed his great head, very slowly, to the smallest creature in the wood.
The lion gave the mouse his life. He did it carelessly. He laughed when he did it. He did not expect to ever see the mouse again, and he did not expect anything in return.
But the small kindness came back to him in a way he could not have planned. The mouse was the only creature in the wood whose teeth were small enough and sharp enough to chew through the ropes.
Jesus once said that whatever you give will come back to you, in the same measure. He did not promise that it would come back the same day. He did not promise that it would come back from the same person. He just said it would come back.
Sometimes the smallest creature you ever spared is the only one who can save you.
What small kindness did you do once, that you have forgotten about?
Where might it have gone?
