I asked for this as a Christmas gift one year because I had heard that it was one of the only (if not, THE only) book on systematic theology that is written by someone who is not a paedobaptist. On that note alone, it was a refreshing change.
Overall, I found it to be readable, concise, well-thought out, logical and devotional.
The grand subject is God, HImself, and Grudem is anxious to extol His praises.
Each chapter ends with questions for personal reflection and application, special terms, a Scripture memory pasage, and a related hymn, so that you can easily use each chapter as an extended devotional.
The only weakness I found with it was his view that special revelation was still possible. This opens up a can of worms. The other was his wavering on Creation. He starts out the chapter strong enough, but then seems to cave to the theistic evolutionists. If you take the stand that theistic evolution is a possibility, then you have death before sin, and the Bible is clear that before Adam sinned, there was no death (therefore no fossils), but when man sinned, death entered the world.
Otherwise, I really enjoyed it, and would recommend it over Louis Berkhof or Charles Hodge or any other Systematic Theology text available.
