Exploring the Causes and Cures of Missionary Attrition

Too Valuable to Lose is a groundbreaking global study that examines why missionaries leave the field prematurely—and what can be done about it. Drawing on research from around the world, it explores both preventable and unavoidable factors contributing to attrition and offers practical solutions from mission leaders, agencies, and field workers. With data-driven insights, case studies, and strategic recommendations, this volume equips churches and agencies to better support missionaries and sustain long-term global engagement.

Does God really care about His servants? Yes!  The Reducing Missionary Attrition Project (ReMAP), launched by World Evangelical Fellowship Missions Commission, seeks to answer that question in this important study. This book utilizes the findings of a 14-nation study done by ReMAP and will help supply some very encouraging answers.
