Modern Christian Theology has the concept of requests made to God in prayer resulting in a response from Our Father, providing the supplicant has faith. This book questions whether this is in fact biblical.
The fact that God is All powerful, has mapped out our lives, does not make mistakes and does not change his mind would suggest that the idea of prayer changing the outcome of the subject we pray for unrealstic.
The fact that suffering is a central theme of the bible and that those that are poor and weak and suffering are blessed by nature of their situation plus the command to forgive our transgressors, not to expect a different outcome if we but pray, would also fly in the face of the concept of being able to change the course of the world through prayer.
The extreme benefit of prayer, including supplication is acknowledged and the prayers of David, Paul and Jesus are examined. The many bible verses that are quoted by many as a promise that a prayer made in faith will result in 'an answer' are examined and their true meaning discussed.
The book is not against prayer. It does in fact promote prayer in all its forms. It is the false expectation that we can tell God what we want to happen and he will do it that is challenged.
