I don't think anyone is denying either the importance of technical study or deep devotion. (I'm certainly not.) But I do have a personal reflection that may help one understand my position:
The closer I got to graduating from seminary, the more frustrated I got with my biblical studies courses. It seemed that more and more we were being forced to occupy ourselves with heavily technical commentaries and resources. They dealt with everything—critical issues, textual variants, historical details, cultural specifics, etc. Yes, they dealt with everything, almost always except one thing: what the text means. I found increasingly, even when using commentaries by evangelicals, that I walked away from the study knowing everything about the surroundings of the text, yet not the text itself. Of course, I understand that all that information is important for understanding the text.
The tipping point for me was when a good friend of mine had points taken off the grade of his OT exegetical paper because he cited Calvin's Commentary on the passage, since Calvin is neither modern nor overly technical. Again, I fully understand that Calvin will not deal with modern controversies over critical theory and historical questions. Yet I never walked away from Calvin without the meaningful import of any given biblical passage weighing heavily upon my soul. But I found increasingly that, at the seminary level, we were far more focused about what Spinoza or some other God-critic theorized, to the utter exclusion of what bearing the text at hand had upon our lives. It was, frankly, life-sucking. I understand and appreciate that we need to be able to converse with these things, obviously.
So, again, I would never say that technical study is unimportant. Of course it is of immense importance. Perhaps I have just been very influenced by Rushdoony and his strong criticism of what he called "constipated theology"—theology that so interested in the abstract and theoretical that it never gets to what theology actually is, "the application of Scripture, by persons, to every area of life" (John Frame, Systematic Theology, p. 8; emphasis added). So, for me, a commentary that does not at the very least conclude with the bearing the text has on our lives is, frankly, not worth much of my time, if any at all. I realize I am drawing somewhat of a false dichotomy (i.e., that commentaries can either be only technical or only pastoral), but in my experience this seems to be the way things actually are, hence my concerns above.
