I had the opportunity of correspondence and a phone conversation with Jennifer Kennedy Dean before she went to be with the Lord. Her books and videos on living a praying life have a helpful biblical scope and grace orientation. Here is some publisher’s information about her best known workbook:

Live a Praying Life(R)! gives readers keys to authentic Christian living through a deepened prayer life. For more than 20 years, Jennifer Kennedy Dean has researched and practiced the principles of her bestselling Bible study of the same title. This new trade edition breaks down and delivers the time‐tested principles of praying. Readers will find it easy to understand prayer–its purpose, process, practice, and promise as they look at prayer through God’s view–His Word. Excellent illustrations and word pictures describe how to get at prayer that pleases God and satisfies the pray‐er’s deepest desires.

Jennifer Kennedy Dean was the executive director of the Praying Life Foundation and a respected author and speaker. Her numerous books, studies, and magazine articles specialized in prayer and spiritual formation, and her work Live a Praying Life(R) has been called a flagship work on prayer. With more than 25 published titles, some of her works include Heart’s Cry, Prized, SEEK, Clothed with Power, Set Apart, Power in the Blood of Christ, Power in the Name of Jesus, Altar’d, and Conversations with the Most High, among others. Widely recognized as an unusually gifted communicator, Jennifer spoke all over the world, calling God’s people to discover the difference between a prayer life and a praying life. She served on numerous boards and committees for ministries focused on prayer and spiritual awakening. She will always be remembered as a respected voice in the area of prayer.
