The book "The Today's Leader as a Key Person for Church Growth?" offers a well-founded analysis of the role of leaders in the context of church growth. Written by Prof. Dr. Michael Herbst, a recognized expert in the field of Practical Theology, the study highlights the challenges and opportunities that Generation X faces in taking on leadership roles within church communities. The work is based on extensive research and reflects the current societal situation as well as Professor Herbst's influence on theological thinking in the German-speaking world. With a particular focus on missionary church development and the relevance of leadership in times of change, this work provides valuable insights for pastors, ministers, and anyone involved in the development of congregations. The study is written in German and consists of 24 pages that address both theoretical and practical aspects of church leadership.
