The amount and variety of evil in our world has often baffled and perplexed believers in God, noted Plantinga. Why, though, should it? Does it perplex observers that water runs downhill? Does it baffle the onlooker to see smoke rise? Is it at all confusing, confounding, or mystifying that fire burns flesh?
God exists. Evil not only exists, but its capacity and potency is increasing as Creation grows more complex over time. Is it not then the case that the volume and variety of evil in this world baffles only because it contradicts the things Plantinga’s believers want to believe? If the truly impartial observer of this world steps outside that contradiction then there is no puzzle, and what once bewildered simply vanishes like steam evaporating over a kettle.
Evil exists because God is evil.
The alternative—God is maximally good but thoroughly incompetent and has lost total control of his creation—is a proposition simply too fantastic to entertain. God, by definition, is maximally competent. There are no mistakes. There can be no mistakes. Evil, therefore, exists because it is meant to exist. Evil is growing more complex over time because it is meant to grow more complex over time. Suffering is growing more potent and expressive over time because suffering is meant to grow more potent and expressive over time. The program is running precisely as designed. The machine has not malfunctioned. Creation is unfurling exactly as the Creator desires.
