The Witness of the Spirit is a clear and comprehensive treatment of the teaching of the Word of God concerning the inner witness of the Spirit of God. The book opens with an account of Calvin's and Luther's contribution to this important theme, followed by a survey of the theological reflection upon this subject from the days of the early Church Fathers to the present time. Dr. Ramm shows that the work of the Holy Spirit is not a single subject to be discussed in isolation from the total area of Christian theology; therefore, he helpfully relates it to the doctrine of the Trinity, of revelation, redemption, and the Scripture; and to Christian fellowship and the spiritual life. Dr. Ramm's book is an invaluable and much needed contribution to a phase of the Spirit's ministry, an aspect long neglected in evangelical thought. ""Bernard Ramm has already distinguished himself by his writings in the area of conservative apologetics and theology. This latest volume from his pen is marked by the same qualities of relevance, forthrightness, and insight by which his writings have come to be so widely known. The Witness of the Spirit was written because of the author's conviction that the doctrine of the testimonium has been sorely neglected in current discussions of revelation and authority. His book is an invaluable study and is sure to stimulate a fresh interest in a most timely and basic topic. When it comes to writing a book that is a must in the area it treats we can say of this volume that Ramm has done it again."" -Dr. Boyd Hunt in Christianity Today Bernard Ramm, professor of Systematic Theology and Apologetics, California Baptist Theological Seminary.
