Thomas Constable's work on Prayer and the Theology of Prayer.
Books on prayer abound, yet books that provide a theology of prayer are virtually nonexistent. Constable describes the forms of communication God invites, unmasks "counterfeits" that pass for prayers, and addresses such difficulties as unanswered prayer. Dr. Thomas Constable graduated from Moody Bible Institute in 1960, Wheaton College, AB (1962), Dallas Theological Seminary, Th.M. (1966), Th.D. (1969) Dr. Constable is the founder of Dallas Seminary
