A little long and maybe slightly confusing if you’re unfamiliar with the world of Narnia. But it still slays me to read it and so I invite you to as well. I’ve always loved Aslan because of how he made Jesus more real to me (more on this in the near future). He’s gracious and loving and king and mighty and magnificent and scary and perfect–all at the same time. And there’s no other place, no other stream, from which to find living water–water that truly quenches and takes away any more thirst.
“If you’re thirsty, you may drink.”
The voice was not like a man’s. It was deeper, wilder, and stronger; a sort of heavy, golden voice. It did not make her any less frightened than she had been before, but it made her frightened in rather a different way. “Are you not 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. And as Jill gazed at its motionless bulk, she realized that she might as well have asked the whole mountain to move aside for her convenience.
The delicious rippling noise of the stream was driving her nearly frantic.
“Will you promise not to—do anything to me, if I do come?” said Jill.
“I make no promise,” said the Lion.
Jill was so thirsty now that, without noticing it, she had come a step nearer.
“Do you eat girls?” she said.
“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. It never occurred to Jill to disbelieve the Lion—no one who had seen his stern face could do that—and her mind suddenly made itself up. It was the worst thing she had ever had to do, but she went forward to the stream, knelt down, and began scooping up water in her hand. It was the coldest, most refreshing water she had ever tasted. You didn’t need to drink much of it, for it quenched your thirst at once.
