We all have questions about prayer. Why pray if God already knows what's going to happen? Can prayer change the mind of God? Does it actually affect anything? What is the purpose of prayer? There is only one wise source to answer our we need to hear from God himself. Only through him and his Word can we have a grounded, balanced, and broad understanding of prayer. This booklet presents an overview of what Scripture says, defining prayer, exploring its roles, and teaching us how to practice it. Basics of the Faith booklets introduce readers to basic Reformed doctrine and practice. On issues of church government and practice they reflect that framework—otherwise they are suitable for all church situations.
