I'm not going to say that this was a terrible purchase; however, Geisler falls into the same trap that most writers of systematic theology fall into, namely, prooftexting. Throughout the four volumes, Geisler (whether his conclusions are true or false) engages in a fair amount of selective citing of sources. This is endemic of systematic theology works because of how condensed they must be. Even the most well-respected systematic theologies (Grudem for example) have a tendency to do this.
With that in mind, this set has considerable value for examining one theological tradition's way of expression, but it should not be used as the definitive answer to all theological questions. Any serious study must examine the entire spectrum of opinions, and we do well to remember that. Much of my discontent is associated with the price of this set. I would be far more prone to suggest the all-in-one volume due to my conviction that the price of the set does not come close to being outweighed by the value of the material contained within.
Nonetheless, I trust that many will benefit from this.
I purchased this set of books before beginning Bible college in 2009. Since then, I've used them for my undergrad classes and now in seminary. Dr. Norman Geisler's scholarship shows within the covers of these volumes.
This collection should be in every pastor, scholar, and Bible students' library.
The overall four volume set is good to have but at times it seems he uses the church fathers to back up his statements and on closer reading (the church fathers) it appears not quite correct. However, I will still continue to read this set and keep checking to see if I am mis reading him or the church fathers.
I am not a Pastor, Professor just a believer that wanted more information about what we as Christians believe. These are amazing books. I found them very helpful. I am just about to start a second read through.
I recently purchased Geislers entire four-volume set of Systematic Theology and I must say that my purchase was long overdue. It is of my opinion that this set should be within arm reach of every serious pastor, Biblical researcher, and Christian professor.
