I have both the 1949 edition as well as the 1981 revision of Thiessen's Lectures and I can honestly say that the 1981 revision is a definite improvement over the original work, while retaining the vast majority of the original author's writings intact.
Contrary to what another reviewer said, the revised version's treatment of the Doctrine of Election is more biblically based, fundamentally sound, and theologically correct than the original and certainly represents the scriptural view of Election more faithfully.
Thiessen's work, though not as complete as other major works of theology, such as those by Hodge, Berkhof, Shedd, or Strong, is an excellent resource for pastors to use as an introduction to the study of systematic theology for church leaders or lay ministers. We use Thiessen in our church for training the ministerial staff and it is highly regarded by all of our church leaders. I highly recommend it.
