While there are many studies and commentaries on the book of Acts, few focus on the amazing achievement of the people found within its narrative. The first Christians chronicled in Acts turned the world upside down in the space of a generation. In this book, Michael Green opens up the gripping story of Acts, highlighting the volcanic eruption of faith described there and comparing it to the often half-hearted Christianity of the modern Western world. Combing trusted scholarship with a popular, enjoyable writing style, this is an ideal book for church, group, or personal study. Green explores the life and faith of the Christians of Acts, answering such questions as What kind of people were they? How did they live? and How did they organize and practice as members of the new church? Besides unveiling the nature of life in the early church, Green discusses how we today can apply the first Christians' dynamic efforts at church planting, pastoral care, social concerns, gospel proclamation, and prayer.
