[5] The book consists of 232 pages and is structured in three main parts: "The Question of an Eternal Hell", "Apokatastasis: Four Meditations", and "What May Be Believed".

[...] The fourth theme is that of the relation between time and eternity, or between history and the Kingdom, or between this age and the next in biblical eschatology, and whether any synthesis other than a universalist one (and especially one that, like Gregory of Nyssa’s, uses 1 Corinthians 15 as a master key) can hold all of the scriptural evidence together in a way that is not self-defeating.

[...] The final theme is that of the nature of rational freedom and of its relation to divine transcendence, and the implications this has for the “free will defense” of eternal perdition.

[7]Hart's arguments are primarily philosophical and theological in nature, yet he also invokes biblical and historical support for his view, citing 23 New Testament texts[8] (including the teaching of Paul in Romans 5:18–19 and of Jesus in John 12:32) which he regards as "straightforward doctrinal statements" of universal salvation,[9] and referencing the teaching of various notable early church fathers (including Gregory of Nyssa and Isaac of Nineveh) which he refers to as "the Christian universalists of the Greek and Syrian East".

[14] Other favorable reviewers have lauded it as "a passionate proclamation of the absolute love of God as revealed in Jesus Christ",[15] and "the work of a stirred and unyielding conscience",[16] whose argument is "forceful, analytically clear, and compelling".

But, in this case uniquely, a strange pattern has clearly emerged: to wit, none of its truly energetic critics in print has thus far condemned it for any claims actually contained in its pages.

[...] Perhaps, then, the inability of certain critics to follow any of the book’s actual arguments is not just obtuseness (though a bit of that, surely), but instead reflects a temperamental incapacity on their parts for confronting any sustained assault on their own understanding of what they believe.
