Book excerpt: On the highways and byways of every continent, hundreds of millions of immigrants are constantly on the move. Because of growing inequalities of wealth caused by unregulated economic globalization, political and ethnic conflicts, environmental degradation, instant communication, and viable means of transportation, more and more people are migrating than ever before. Crossing international borders, whether compelled or voluntarily, is a major characteristic of our present epoch. No countries or regions are immune from this reality. Facing the growing scope, complexity and impact of the current worldwide phenomenon, God's People on the Move seeks to develop appropriate biblical and missiological responses to the issue of human migration and dislocation. The book is divided into two major sections. Part one, "Biblical Perspectives on Migration and Mission," contains six essays that focus on various biblical themes or texts that deal with migration and mission. Part two, "Contemporary Issues of Migration and Mission," contains six essays that address different immigration issues around the world. The contributors to this volume are women and men from different ethnic backgrounds, working and living on five continents. The internationality of the contributors gives this volume a unique global perspective on migration and mission.
