This book was written with three purposes in mind. First is the ministry, that is, pastors and church leaders facing crises for the church in mission. This book will help them guide and mentor people through being missional in times of crisis. It will help pastors, leaders, and students in developing mission strategies for ministry in times of crisis. Second, this book was written to provide a better understanding of the early church as a model for overcoming crises. It matures the concept of the church and its mission in the present, contributing to new mission strategies for the contemporary church in mission, facing crises. The third purpose is personal. This book was written because of Augusto Rodriguez's experience as a pastor during the crisis of the COVID-19 pandemic of 2020, something unlike anything he had faced in thirty years in the ministry. He also wrote this book to coach/mentor other pastors and leaders going through an experience like his and to present the insights learned from the study of the early church in Acts of the Apostles, examining the ways they overcame different crises that could apply to the contemporary church in mission.
