""Bob Callahan is a man who loves the Scriptures and loves the God to which they attest. His lessons on Ephesians are deep and rich. Bob has as his conversation partners the great minds and spirits of the church, and he is at once very readable and very faithful."" -Todd B. Jones Pastor, First Presbyterian Church Nashville, Tennessee ""One would be hard-pressed to find a more thorough investigation of the treasures of Ephesians than what Mr. Callahan has written. The author has taken meticulous care to draw from the epistle as many of the theological riches as he could glean--and the reader could digest. No one will put his book down without a deeper appreciation for the relevancy of Paul's insights and teachings as given first to the church at Ephesus and now, by God's grace, to us."" -Norman H. McCrummen III Senior Pastor, Spring Hill Presbyterian Church Mobile, Alabama ""One of the most interesting recent developments in churches concerns the renewed focus on the doctrine of the Trinity. While historians of Christian thought and systematic theologians have been exploring the complex metaphysical issues, church members are beginning to recover the devotional and spiritual origins out of which this doctrine first rose into prominence. Robert Callahan's book is a fine example of the way in which a layman has approached this magnificent topic in a spirit of Bible study and prayer."" -Richard Ray General Editor of Kerygma Bible Studies Former Managing Director of John Knox Press
