Book excerpt: The Church's New Front Door introduces Christians to the critically important concept of the Fourth Industrial Revolution, an era that will be dominated by powerful technologies like artificial intelligence (AI) and advanced robotics. While the Fourth Industrial Revolution is powered by technological developments, it has far-reaching political, socio-economic, ethical, and spiritual implications as well. To be missional, the church needs to be relevant; and in order to be relevant in the twenty-first century, believers must engage with novel technologies and the impact they are having on areas like work, education, and healthcare. Each chapter includes discussion questions and suggestions for further reading, making this book an accessible resource for diverse audiences, including church members, ministry leaders, and students at Christian colleges and seminaries. Whether you agree or disagree with the author's description of how our world might change in the next ten to twenty years--this book will make you think!
