"God uses physical elements to communicate with His People....

And we enter into communion with Him by means of the universe he created. He chose bread as the most perfect way by which to enter our lives.

And what is the bread? Flour, yeast and water, baked to a certain temperature? No, it is much more.

You need the whole world.

The earth hast to turn, the rain has to fall, the soil must be fertile, the sun must shine, night must come, the wind blow. If all this is in harmony, and humans interact with it appropriately, tending the garden as God originally planned, bread can be baked, communion with God restored."
