Book excerpt: Central to the Christian life is the practice of prayer. But what, theologically speaking, is going on when we pray? What does prayer have to do with religious belief and action? Does prayer make a difference? Prayer: A Guide for the Perplexed addresses these and other key questions regarding the Christian theology of prayer. Beginning with Evagrius of Ponticus's 'On Prayer', Ashley Cocksworth finds in this early document a profound expression of the 'integrity' of the experience of prayer and theological thought. Seeking throughout to integrate systematic theology and the spirituality of prayer, individual chapters explore the meaning of some of the core doctrines of lived Christian faith – the Trinity, creation, providence, and the Christian life – as they relate to the practice of prayer. Complete with an annotated bibliography of sources on prayer to promote further reading, this volume appeals to academics and general readers alike.
