Book excerpt: This book considers in detail the key drivers of globalization, its contemporary shape, and its implications for world mission. It also looks at the impact of globalization on different contemporary issues affecting mission such as ethnicity, the environment, and global health as well as globalization's effect on more traditional "missionary" questions of the world religions, contextualization, theology, and the church. One World or Many? is written by a variety of authors from all over the world. This book was published in partnership with the World Evangelical Alliance.
