It's Gretchen's turn to talk about books that have been influential on her life. This puts Gretchen and Katie on a couple of tangents about reading outside of your denominational tradition, and interacting with ideas that you disagree with in order to shape and develop your thinking. This episode also reveals Katie's role in Gretchen's life to prevent her writing from getting "too Ann Voskamp-y."

From catechisms, church history, to Lutheran spirituality, studies on the Holy Spirit and of course GRACE, this episode covers a range of topics.
