Not only are the breadth and depth of Darrell Guder’s theological and missiological work over the last half century on display through the essays collected in this book, but his ideas are celebrated in the way any leading scholar would be honored by: through critical retrievals and constructive reappropriations intervening in important contemporary conversations. That the future of the theological and missiological endeavors will be even more closely intertwined than ever will be a part of Guder’s legacy, which is solidified and extended through this volume.

Darrell Guder introduced me to the field of missiology in his own gracious, humble way. His work, especially on missional ecclesiology, has influenced my own thoughts and inspires my students. In addition, with all the warmth of his personality he helped me find my bearings in a discipline that was relatively new to me, and he introduced me to some brilliant students of his, both as colleagues and as PhD candidates. In short, as a brother and as a colleague, Darrell has been extremely important to me. This volume is a great tribute to the width of his theological scopus, his love for the church (and, of course, Karl Barth!), and his passion for Christian witness to a secularizing culture. I pray that God will bless it to carry Darrell's missiological heritage further into this exciting century we are living in.

Back in the day, missiology was focused on the work of missionaries overseas. Now, largely due to the theological groundwork of Darrell Guder, it is as likely to be about the local church...In paying tribute to Guder's work, this book has become a valuable introduction to contemporary missiology as a whole.
