Letters to Doubting Thomas: A Case for the Existence of God

Letters to Doubting Thomas is an exchange of letters between two characters on the existence of God; it provides a cumulative case for Theism (the belief that God exists). Chapter by chapter, theism is compared with Naturalism (roughly, the view that there is no God and that ultimate reality is physical reality), concluding that Theism (on balance) provides a better explanation of the world and human life than does Naturalism.
