In this volume, a top scholar in the world of evangelical theology addresses the key soteriological theme of union with Christ. The book provides substantive engagement with the doctrine of transformative union, including sections on the creeds, Scripture, the history of the doctrine, constructive dogmatics, and Christian praxis. Its biblical point of access is Paul's theology of life "in Christ," understood as an invitation to a theological reading of the four Gospels. Special attention is given to the trinitarian structure of union with Christ. This book shows students how to integrate theology into the life of faith and demonstrates how the practices of Christian worship influence theological thinking. A devotional interlude directing readers to a classic hymn, poem, or liturgy follows each chapter. The Soteriology and Doxology series consists of introductory textbooks that cover key topics in soteriology, providing substantive treatments of doctrine while pointing to the setting of theology in doxology. Series editors are Kent Eilers and Kyle C. Strobel.
