This book by Wayne Grudem is a condensed version of his work on Bible Doctrine, which itself is a condensed form of his excellent Systematic Theology. In this briefer work we get twenty chapters of very clear and concise descriptions of key doctrines of the christian faith. Grudem deals well with each subject, including some thorough chapters on heaven, hell and the final judgement. It must be added that this is not just a book of 'dry theology,' as there is plenty of practical application throughout the book, and it is good devotional reading.
It is worth noting, that concerning the Second Coming of Christ, Grudem favours a classic pre-millenial position, although he very fairly explains other views on this subject. This short book does not contain Grudem's views on spiritual gifts. For, this you would need to consult some of his aforementioned more extensive writings.
The book ends with sections containing historical confessions such as the Apostle's Creed, and also some recommended further reading. I recommend this book to christians both old and new. It should be of great spiritual benefit.
