SJ Gamertsfelder is my wife's great grandfather. I have the hard copy of this book and have used it for devotional reading for close to 50 years. I also know the backstory of the work and challenge of this work being originally published, as well as the story of this man's dedicated life and ministry. He is for me one of the great evangelical leaders of the past that deserve to be remembered. I am excited to be able to include his theology as a part of my Logos library where I can blend it into my searches and studies.
