Why do bad things happen, even to good people? If there is a God, why aren’t God’s existence and God’s will for humans more apparent? And if God really does miracles for some people, why not for others? This book examines these three problems of evil - suffering, divine hiddenness, and unfairness if miracles happen as believers claim - to explore how different ideas of God’s power relate to the problem of evil. Keller argues that as long as God is believed to be all-powerful, there are no adequate answers to these problems, nor is it enough for theists simply to claim that human ignorance makes these problems insoluble. Arguing that there are no good grounds for the belief that God is all-powerful, Keller instead defends the understanding of God and God’s power found in process theism and shows how it makes possible an adequate solution to the problems of evil while providing a concept of God that is religiously adequate.
