I had not read much of Jurgen Moltmann's work before reading this. I am amazed and impressed with this work. He indicates his late conversion to Christianity and "curiosity" being his only theological virtue has made him less systematic and tied to a particular tradition's defense in his theology. The former is almost certainly too modest and the latter is not as true as he would like. (He definitely shows his Calvinist and Lutheran roots here, but in surprising ways.)
What I find most meaningful in this work is that, unlike many other works on eschatology (theology of the end of history, personal death, eternal life, etc.) is that it actually takes the links between a person's death as a person, the path of history, and the promised biblical consummation and renewal of all creation seriously and strives to integrate them. His writing is very lucid and this English translation is well done.
I would say the most moving material is in his chapters on "Death as a Consequence of Sin or Life's Natural End," "Where Are the Dead?" and "Death, Mourning, and Consolation." He lays down a consistent theological view that says that given what God has promised we can do no less than expect that the whole person God has created dies wholly, is raised as a whole person, and glorified.
This takes on even greater meaning when he spends a significant part of the middle of the book eschewing all forms of historicized eschatology (in the form of reactionary and utopian visions - and instead of retreating from the political sphere, seeks to ground the quest for transformation of the world to more justice and ecological sustainability in the reality of God's faithfulness to the promise of salvation and the redemption of all things. His understanding of the Last Judgment is masterful, as is his chapter on cosmic eschatology which argues for the scriptural perspective of the real renewal of the entire cosmos in eschatological glory. Overall, I find his general theological schema of nature - grace - glory to be a rich one.
Moltmann seeks to show the problems with traditional views of eternal life without a body (the immortality of the soul alone) and how things like the nuclear and ecological threats being experienced today with the possible extinction of much of the life on earth help us recognize that we as a people on this planet, for the first time in history, live with a time limit. We can't undo what has been done, but we can work toward the vision that God has for creation to keep pushing back the time limit. Of course, Moltann recognizes that any transformation of the world to the full Reign of God is in God's hands, not humans. But he recognizes that commitment to the God of Jesus Christ admits of no effort to flee the world's troubles or to become airy gnostics or docetists.
There are times when Moltmann, for all of his concreteness in other areas, reverts to an essence ontology in describing God's 'making space and time' for creation by 'withdrawing himself and his omnipresence' and then will, in the end, restore his full presence and so renew creation. At times, I wish he had been more consistently Trinitarian in articulating the relationship of creation in time to the renewed creation. I also think that he still presents a fully consummated reality that is just a bit too "content" with a 'passive' dwelling in God.' I am sure there must be more to do for eternity and that God's creative abundance will continue to shape and mold reality in new ways. Because if Moltmann's view of eschatology is right, and the entirety of human history will ultimately be transfigured and redeemed, I anticipate there will be quite a lot to do, even in eternity!
