Guest speaker Andy Gerhart's sermon delivered on July 24, 2016. We know that knowledge is power, and in our UU faith we emphasize the free search for truth. But what does it mean when answers lead to new questions and new forms of ignorance? How do we cope with our ignorance and simultaneously act in good faith? We'll discuss our current climate crisis as we explore how uncertainty might ground our theology to inspire us and offer a basis for moral action.
