The letter of James is not a haphazard collection of wisdom sayings, but a carefully assembled document with a unifying motif, according to Daniel K. Eng. By examining the structure and content of the epistle, he shows that James contains a coherent and consistent message of eschatological approval, that is, a favourable verdict at end-time judgment.

Eng establishes that James begins with a prologue (1:1-27), indicating the author's concern for the hearers to receive eschatological approval. After that, Eng studies the document's structure indicated by cohesive ties and bracketing, offering an informed outline for James 2-5.

With the outline in view, Eng shows how the content of each subsection refers to a favourable eschatological outcome. Discourse analysis plays a crucial role here, because the epistle's author indicates the prominence of certain concepts through word order and dependent clauses.

Finally, Eng argues that James 1:12 serves as a thesis statement for the whole epistle, pointing the hearers to their route to a favourable end-time judgment. His resulting outline of James resembles a fish skeleton, with the unifying motif serving as a spine. Ultimately, this volume shows how the epistle's structure and content alike point to its unifying theme: eschatological approval.
