Mr. Robertson's book is well worth the reading for those seeking a very, very basic introduction to the idea of the system of covenants in Scripture being not Dispensations but part of a united whole. It comes from a Reformed/Calvinistic background. It is most likely written from a a-millenial which some post-millenialists may not appreciate. The author is also very repititive in his remarks which methinks is necessary. The book could have been much shorter without the redundancy. Nonetheless, a good primer for those seeking information on the covenants.
