Earthquakes, tsunamis, and disease kill innocent people, and no human free choice explains them, so a good God cannot be in control.

Why people find it persuasive

The free-will defense addresses moral evil, but it does not obviously explain natural disasters. Hundreds of thousands died in the 2004 Indian Ocean tsunami, and the scale of suffering seems incompatible with a loving Creator.

Important distinctions

• • Moral evil versus natural evil.
• • Gratuitous suffering versus suffering that has a justifying purpose.
• • Whether we are in a position to know that no good reason exists.

Christian response

• • Plate tectonics, which causes earthquakes, also recycles minerals and sustains the carbon cycle that supports life. A stable, law-governed world requires regularities that sometimes harm.
• • Richard Swinburne argues that natural laws enabling knowledge and meaningful action require that harm be possible.
• • Some thinkers, such as Alvin Plantinga, propose that unseen agents or a fall might affect nature, though this is more speculative.
• • Christianity does not claim to explain every instance; it claims God entered suffering in Christ and promises to end it (Romans 8:18-25, Revelation 21:4).

Christian counterresponse

The response is partial. Theists acknowledge mystery but argue that the evidence of a loving God, including the resurrection, supplies a reason to trust despite the unanswered cases.
