“Luther learned to draw life from the struggle against the Devil. For the just shall live by faith, and ‘life’ does not begin in Heaven. According to the medieval memento mori [Latin: Remember that you have to die], in the midst of life we are surrounded by death. Luther’s faith enabled him to vigorously turn this on its head: ‘In the midst of death we are surrounded by life.’” – Heiko Oberman, Luther: Man between God and the Devil (1982) 330.
