"There is no other stream"

The birds had ceased singing and there was perfect silence except for one small, persistent sound, which seemed to come from a good distance away. She listened carefully, and felt almost sure it was the sound of running water.

Jill got up and looked round her very carefully. There was no sign of the lion; but there were so many trees about that it might easily be quite close without her seeing it. . . . But her thirst was very bad now, and she plucked up her courage to go and look for that running water. . . .

The wood was so still that it was not difficult to decide where the sound was coming from. It grew clearer every moment and, sooner than she expected, she came to an open glade and saw the stream, bright as glass, running across the turf a stone's throw away from her. But although the sight of water made her feel ten times thirstier than before, she didn't rush forward to drink. She stood as still as if she had been turned to stone, with her mouth wide open. And she had a very good reason: Just on this side of the stream lay the Lion. . . .

How long this lasted, she could not be sure; it seemed like hours. And the thirst became so bad that she almost felt she would not mind being eaten by the lion if only she could be sure of getting a mouthful of water first.

"If you're thirsty, you may drink." . . .

For a second she stared here and there, wondering who had spoken. Then the voice said again,

"If you are thirsty, come and drink." . . .

It was deeper, wilder, and stronger; a sort of heavy, golden voice. . . .

"Are you thirsty?" said the Lion.

"I'm dying of thirst," said Jill.

"Then drink," said the Lion.

"May I — could I — would you mind going away while I do?" said Jill.

The Lion answered this only by a look and a very low growl. . . . The delicious rippling noise of the stream was driving her nearly frantic. . . .

"Do you eat girls?" she asked fearfully.

"I have swallowed up girls and boys, women and men, kings and emperors, cities and realms," said the Lion. It didn't say this as if it were boasting, nor as if it were sorry, nor as if it were angry. It just said it.

"I daren't come and drink," said Jill.

"Then you will die of thirst," said the Lion.

"Oh dear!" said Jill, coming another step nearer. "I suppose I must go and look for another stream then."

"There is no other stream," said the Lion.

Jesus said to her, “Everyone who drinks of this water will be thirsty again, but whoever drinks of the water that I will give him will never be thirsty again. The water that I will give him will become in him a spring of water welling up to eternal life.” - (John 4:13-14 ESV)
