The book is, primarily, a linguistic investigation into the possibility that the Johannine farewell discourse is the product of multiple hands. Chapter 1 examines the history of the problem. Chapter 2 contains an examination of the stylistic unity of the farewell discourse and John 14:31-16:33 is examined for specific literary style markers. All the style tests show that the major divisions of the farewell discourse are consistent with the style evident in the rest of the Gospel. Chapter 3 contains an investigation of the structure of the farewell discourse. The text is tested for structural unity, textual prominence, and coherence. The results show that the discourse holds together quite well in structure, peak, and cohesion. Chapter 4, therefore, returns to the issue of the magnus reus (Latin for "the great litigant"). The difficulty presented by 14:31, (ultimately, the major reason for identifying editorial activity) is investigated in terms of the assumptions current among source critics. Upon a closer examination, these assumptions are shown to be unlikely based on the conventions of ancient literature and the literary conventions of participant movement in the rest of the Fourth Gospel. The conclusion reached in this work is that the farewell discourse should be considered a unity. Journal for the Study of the New Testament Supplement Series, 256.

Through the lens of John the Apostle's Farewell Discourse found in John 13:31 - 17:26, seminary professor L. Scott Kellum provides a step-by-step illustration of how to produce an expository sermon series in "Preaching the Farewell Discourse."
Kellum begins with foundational tools that will aid the journey from text to exposition and then describes how to employ discourse analysis to a hortatory passage (like the Farewell Discourse) or an expository passage.
In the latter part of the book Kellum applies the theory to the Farewell Discourse of John's Gospel, examining the process in three sections: analyzing the text, interpreting the text, and preaching the text.
