This reading is from the Shabbat Outreach materials used by Emerald Pond (uncredited in those materials):
When the world was created,
G-D made everything a little bit incomplete
Rather than making bread grow out of the earth,
G-D made wheat grow so that we might bake it into bread.
Rachter than making the earth of bricks,
G-D made it of clay so that might bake the clay into bricks. Why?
So that we might become partners in completing the work of creation.
