To make us realize the full extent of human sin, God does not merely allow personal evils (i.e. the disordering of our souls and the sins we commit as a result) to run their course subsequent to the Fall. In addition, God allows natural evils (e.g. death, predation, parasitism, disease, drought, floods, famines, earthquakes, and hurricanes) to run their course prior to the Fall. Thus, God himself wills the disordering of creation, making it defective on purpose. William Dembski, The End of Christianity, p.145
Notice that according to Dembski, God purposefully designed the evils of the natural world, "making it defective on purpose."
What a valuable concept! Defective Design (DD)! It will be interesting to see how Dembski and others who believe in DD will incorporate it into their "design inference."
