If you read the sermons from the great men of God through church history (Luther, Calvin, Edwards, etc.), very little time is given to practical application.
I'd like to offer a bit of clarity on this stipulation.
If you read Puritan sermons, and Jonathan Edwards is certainly a kind of epitome and exemplar of the class (especially the latter-era),
you will find
e x t e n d e d instances of "Use." Use of what? you ask. Use of the Doctrine. The Puritans certainly preached extensively through portions of Scripture, but not as often or with as much rapidity as the 1st generation Reformers. Many of their sermons left for us today are extended treatments of a single verse.
From "the text," typically a verse, or sometimes even a part of a verse, the Puritan preacher extracted the Doctrine. This was overall a rather limited portion of the message, might be a little shorter or longer, depending on how much effort went into proving that the point drawn was, truly, the biblical author's intent, or justly and properly deduced from it. The Doctrine was boiled down to a proposition.
And then followed a typically more lengthy section concerning "Use." Such use went all over: from divine adoration with respect to the truth, glory given to Christ or to any or all the Three Persons, judgment against sin contrary to the doctrine, further development of the doctrine or establishing its place in the broader system of doctrine, the doctrinal relation to the church's manner or function, and (inevitably) exhortations to personally efficient thoughts and impulses tied to the doctrine.
To be sure, many elements or numbers (1,2,3...) of the "Use" we might tend today to classify simply as developed "Doctrine." Because we aren't used to thinking of necessary conclusions to bald-doctrine on the surface of the text, as itself being doctrine; nor of the right pleasure in such investigations (kind of like "music appreciation," or some other subject) as actual "application" or use. Our anti-intellectual age can't be bothered with time spent in such appreciation, and wants only to rush on to "what is the cash-value of this proposition." If there isn't much to
DO from that text, well then: give me a
better text.
Now, someone like Matthew Henry (another Late Puritan) had apparently more of a running, expository style, if his commentary and the outlines therein give us much indication of his practical style. His pulpit guidance was more immediate, and followed the flow of the text. But still one can see how this "integrated style" also sought grounding for whatever exhortation or application (use) given, from the text.
So, what I'm trying to emphasize is that there is an
order to Reformed and Puritan sermons--Doctrine, then Use, and sometimes other intermediate divisions such as "Exposition" or "Exhortation," things like that. And not always greater length of time or energy given to the Doctrinal portion of the sermon. Sometimes, a thing said simply and well is sufficient for building quite a bit of superstructure upon it.
