I am thankful for the vision of Kyle Duncan, who was willing to deal with the ephemeral territory of extraordinary spiritual experiences. Also, to Julie Smith and Ellen Chalifoux, who provided expert editing and critical judgment on a challenging topic. Thanks also to Jeanette Littleton for her invaluable assistance, and to Andy McGuire and Tim Peterson for their aesthetic input. And to the contributors who were willing to share their most intimate encounters with the supernatural, who prove that God is still working in mysterious and exciting ways.
