Parable of the Yeast

Check out this drawing by Colin. The tiny mustard seed has grown into a tree that casts a monstrous shadow. The Yeast does the same thing in the process of baking bread. What is this guy thinking? What yeast or mustard seed experiences have you experienced? Does anybody know what happens chemically when yeast and warm water are added to the ingredients that go into making bread?

Parable of the Friend at Midnight (10/03/10)

This parable is about prayer. Here is a poem written by C.S. Lewis titled "Prayer" and published in 1964 in a book called Poems.

Master, they say that when I seem
To be in speech with you,
Since you make no replies, it's all a dream
-- One talker aping two.

They are half right, but not as they
Imagine; rather, I
Seek in myself the things I meant to say,
And lo! the wells are dry.

Then, seeing me empty, you forsake
The Listener's role, and through
My dead lips breathe and into utterance wake
The thoughts I never knew.

And thus you neither need reply
Nor can; thus, while we seem
Two talking, thou art One forever, and I
No dreamer, but thy dream.
