In 1962 meterologist Lorenz simulated weather patterns with some simple mathematical formulas on his computer. For a while the results were predictable. But then, with very minor changes, the results went wildly erratic. Lorenz saw that the weather would change utterly if you started things out just a little differently. No wonder real weather is so unpredictable! Weather obeys physical laws. But if you change one breath of air, those laws will spin out in a wholly different story. Lorenz came to call this unpredictable result the "butterfly effect". That is, a single beat of a butterfly's wings in Brazil can change the weather in Beijing!

I was pondering God's perfect creation described in the Genesis story. How is it that a simple error in Adam's part could set in motion a catastrophic series of events that created pain and suffering for billions of God's creation? Never mind Adam. How is it that Satan was allowed disobedience and imparted with so much power?
