What can I say? For better or worse, Dr. James White is one of my favorite scholars. While for some he rubs them the wrong way, in recent years, for me, he has scratched where it itches. John 6 is one place where I had a substantial itch that I thought was scratched.
I look back on my notes taken while in seminary on John 6 and I find them sparce. On the one hand, I'll blame my own notetaking ability. On the other hand, what I did write is exegetically anemic. This short booklet (under 100 pages, including endnotes) is exegetically stout while also carrying theological weight. His argument is rooted in not merely the English text of John 6, but his expertise with the original Greek is also on display. He follows the argument of the Lord from start to finish without the need to jump past verses or jump to contexts foreign to John 6.
While most of the book is focused on solid exegesis of the text, since John 6 is a text traditionally appealed to in defense of the doctrines of grace, White similarly broaches these doctrines as well. So human inability, effectual grace, preservation of the saints, and the whole lot of the doctrines of grace make their brief appearances in this work also.
