This book sets a number of biblical prayers in the context of biblical revelation so that they are seen as celebrations of God's great saving deeds of the Exodus and the Resurrection. Thus they bring us into the very heart of the experience of salvation in that ultimate prayer-event that is the Eucharist. In this context prayers of petition become acts of trust in the goodness of the God who entered out world definitively in the person of Jesus Christ, while prayers of gratitude covert the lives of believers from fear and guilt to courage and joy.
