The James Expository Preaching Kit (M) helps you plan an expositional sermon series by curating a trifecta of the best Bible study materials on James you need to prep and preach.
It includes everything in James Expository Preaching Kit (S) plus resources like the Dictionary of New Testament Background, Hebrews–James (Smyth & Helwys Bible Commentary | SHBC), and Hebrews and James (Reformation Commentary on Scripture Series, NT vol. XIII | RCS).
