I have appreciated the key point list, chapter summary and study questions at the beginning of each chapter. He does a great job of presenting alternate views of each topic before stating his theological position.
This is an excellent systematic which goes in depth on almost every topic it covers. I wouldn't necessarily classify this as a technical work but its more in-depth than Grudem's systematic. However, anyone can read and profit from it. It will be a welcome addition to any student's library.
"Compact" may not be the right word for this hefty tome but, given the scope it covers, I think it describes each chapter. Erickson states his own views and conclusions; but only after fairly and accurately giving those of others. An excellent one-volume work!
Erickson treats the topic of God with detail and caution, yet at the same time beautifies the study of God. The vast knowledge one has to have in order to write a succinct text on systematic theology is incredible. It has, and will continue for a period of time to be a great work on systematic theology.
