The Atonement is the most significant aspect of our salvation wrought by Jesus Christ on our behalf and this book which deals with the atonement in depth is the most significant contribution to the Christian church by the nineteenth century Scottish Calvinist-Hugh Martin. He was a theologian of extraordinary grasp and great power and is considered one of the masters of Covenant Theology heralding from Scotland. For creative brilliance paired with reverent orthodoxy Martin outshines them all, on both sides of the Atlantic. Martin's keen analytical mind also distinguished him as an outstanding mathematician. At a time when the preaching of the cross has been displaced from many pulpits by a therapeutic-moralistic deism, and where experience-oriented, utilitarian teaching has eclipsed sound doctrine, Hugh Martin's exposition of the atonement as it relates to the Covenant, the priestly work of our Lord, and upon the intercession and the mediation of our Lord is a work that demands the attention of every pastor and lay-person as well.
