It has been over 40 years since I was pastor here in Täbingen from 1972 to 1974. And now you have asked me to speak to you about what keeps faith alive, what nourishes it, so that it does not dissipate and die away, speechless, mute. How is it that faith that once was vibrant and fervent can become dull and silent? And how does it happen that those who once were joyful in faith, and full of love and gratitude, can become apathetic or cynical, despondent or indifferent, listless and lethargic? Their expectations of God have flagged, they are without hope, their love has grown cold, their faith is lost, dead. There can be many reasons for the death of faith, for the loss of the unconditional trust and confidence that faith is. When faith is lost, spiritual attack (Anfechtung)—that tremendous challenge to faith—has triumphed. In such times, the only thing that can stand up to this attack, that can resist it, is that which gives life to faith, keeps it alive, and keeps creating it anew as it overcomes the attack.
