Since its publication a decade ago, Let the Nations Be Glad! has provided thousands of seminary students, missionaries, and pastors with a sound theological foundation for missions. Piper now offers a revised and expanded edition of this theological and biblical defense of God's supremacy in all things.

This revised and expanded edition contains updated references to contemporary literature and debates and new illustrations and quotations. This edition also contains a new preface and a final section devoted to the practical outworking of compassion and worship. Included in this new section is a chapter encouraging passion for God's supremacy and compassion for man's soul, based on Jonathan Edwards's musings on the unity of motives for world missions. Concluding this section is a chapter containing Piper's reflections on New Testament worship as an inner reality more than an external form.

In the new preface Piper explains who this book is for:
This book is not just for missionaries. It is for pastors who (like me) want to connect their fragile, momentary local labors to God’s invincible, eternal, global purposes. It’s for lay people who want a bigger motivation for being world Christians than they get from statistics. It’s for college and seminary classes on the theology of missions that really want to be theological as well as anthropological, methodological, and technological. And it’s for leaders who need the flickering wick of their vocation fanned into flame again with a focus on the supremacy of God in all things.
