This book investigates the efficacy and underlying logic of prayer from an interdenominational Christian perspective. The authors, theologians from seven different denominations, explore whether prayers are answered by divine intervention or are a form of self-reflection. They address the persistence in prayer despite a lack of perceived divine response, examining the systematic theology, liturgical, and historical approaches to prayer, and its external reasonableness.

The book presents a scholarly examination of prayer, drawing on theological insights from various Christian traditions. It aims to provide a comprehensive understanding of the logic and practice of prayer, addressing fundamental questions about faith and the divine. The collection of perspectives suggests a text that is both informative for those interested in Christian theology and potentially challenging to conventional views on prayer's effectiveness.
