As you study the many Scripture references, you will build a solid foundation for successful prayer ministry. You will learn how to begin a prayer ministry in your church/conference/union/division.
Subsequent chapters build the framework of effective prayer ministry leadership as well as prayer ministries for intercession, children, and evangelism. Several chapters teach how to pray effectively. They also delve into blessings to pray for, various forms of prayer, and conditions of answered prayer. A final reference section includes key quotes from Ellen White on prayer and an excellent bibliography of prayer resources.
