In the preparation of this Commentary, my aim throughout has been
evangelical and practical. A study of the Book of Isaiah suggests many historical,
critical, and speculative questions, but these I have entirely disregarded.
I have asked only, What messages from God has this inspired prophet for the
men of this generation? What instruction has he to give us? What warnings?
What encouragements? What consolations? To these questions I
believe there are answers in the outlines I have myself prepared, and in those
I have obtained from other sources.
As my work proceeded, my methods somewhat changed. I discovered
that I had commenced the Commentary on too large a scale, and that it was in
danger of becoming too large and costly. I therefore ceased to append illustrations
to the outlines, and contented myself with giving references to illustrations
in my “Homiletic Encyclopædia of Illustrations in Theology and Morals”
and my “Dictionary of Poetical Illustrations,” using for this purpose the letters
H. E. I. and P. D.
I also ceased to prepare outlines on all the texts, and limited myself to
those most likely to be profitable to ordinary congregations.
As I proceeded, I also became more convinced that a book intended to be
helpful to many minds should contain the best thoughts of many minds; and
therefore, instead of preparing outlines which might be expanded into sermons,
I condensed sermons preached by others into outlines. Remembering that I
was working for ministers, I stripped the thoughts contained in those sermons
of most of their dress, and so the substance of a sermon of twenty pages was
frequently placed on a page. The result is that in this volume a hundred and
fifty students of Scripture—Episcopalians, Presbyterians, Congregationalists
and Baptists—combine to offer to their brethren suggestions as to the best
practical uses to which the writings of Isaiah may be put today.
On pp. [447]–496 are some valuable outlines obtained too late for insertion
in their proper places. Three of them are interesting specimens of Welsh
preaching.
