Writing from the perspective that the coming of God's kingdom is both present and future, Hoekema covers the full range of eschatological topics in this comprehensive biblical exposition. The two major sections of the book deal with inaugurated eschatology (the "already") and future eschatology (the "not yet"). Detailed appendix, bibliography, and indexes.
Put simply, Hoekema's book is simply a classic. Whether one agrees with him or not, one cannot find a better introduction to eschatology available from an amillennial perspective. There are a few unique contributions that this book contains:
(1) It shows how one can and should apply the already/not yet tension in eschatology. One cannot find this emphasis in many lay accessible books.
(2) It is not sensationalistic. While passionate about the things to come, he is careful not to fall prey to making prognostications.
(3) It does a good job of surveying the various millennial (and other eschatological) options in Christianity today without being overly simplistic and/or misrepresenting another position other than his own. This being so, he fairly and irenically shows why he holds his position.
(4) It represents a particular brand of amillennialism that understands the earthly prophecies of the OT not to refer to spiritual fulfillment in the church today (as many amills do), but in the new heavens and the new earth. In fact, his emphasis on the new earth in his book is surprisingly insightful.
(5) It also gives a very nice appendix which surveys the more recent developments in eschatological discussion (e.g., Cullman, Moltmann, Bultmann, Schweitzer, et al).
I do not agree with Hoekema on many issues. For instance, I am a partial preterist, and so I see a few passages in the past that he sees as still future. Also, I am a postmillennialist, thus seeing a more prosperous future for the pre-Advent church. Despite these differences, however, I gained a tremendous amount from reading Hoekema's book -- insights which I hope to help my own eschatological understanding to become more fully biblical. Let's all face it -- none of us probably has all our eschatology completely right. We need each other to appreciate all the variations and viewpoints the bible offers (see Poythress' "Symphonic Theology" for more on that subject).
Whoever you are and whatever position you hold, it is doubtful that you can NOT benefit tremendously from a good reading of this book. If anything, it may just correct a misunderstanding of the amillennial position that many have today.
