For thirty years Dr. Thiessen's Lectures in Systematic Theology has been used as a standard reference work in Bible institutes, colleges, and seminaries across the nation and throughout the English-speaking world. The broad acceptance enjoyed by this text has come in part, no doubt, because of Dr. Thiessen's careful and extensive use of scripture and his dispensational approach to theology. In light of current theological trends and emphases and more recent studies in the various divisions of biblical doctrine, an update of his material seems warranted. - Preface to the revised edition.
