Clearly Mr. Milbank is mistaken. God is not punishing anyone, yet. One need only read the Bible to find that weather and earth movements are simply part of 'normal' behavior by the earth.

 Although Jesus did predict an increase in earthquakes prior to His 2nd Coming, He didn't say they were, in fact, acts of God.   " He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous."  Mathew 5:45

 Ecclesiastes 9:11  it states that "time and chance happen to..all"  My firm belief is no one is being punished by God at this time. I believe anyone who claims that it is, they're  in error.

  If its always raining on you, wherever you go, its not an act of God. Nor is the sun shining on you all the time evidence that  you are somehow virtuous.
