A common refrain from non-religious people is that belief in God is akin to a mental disorder. Well here are a few resources which should help put things into perspective and show how a theist is comfortably warranted in their religious beliefs:
- Bruce A. Little What is faith? Does belief require Warrant?
- Bruce A. Little The Formation of Belief
- William Lane Craig Religious epistemology
- Alister McGrath Is God a Delusion?
