If God exists, why is there evil and suffering?
Objection: A good, all-powerful God would eliminate evil. Since evil exists, God cannot.
Response: God permits suffering because he values free will and works through suffering for greater goods. The cross itself is the greatest evil producing the greatest good — God doesn't merely observe suffering, in Christ he entered it.
