The full title of Dr.
Owen's great work runs thus: _The Nature, Power, Deceit, and Prevalency of the Remainders of Indwelling Sin in Believers_--a title that will tell all true students what awaits them when they have courage and enterprise enough to address themselves to this supreme and all-essential subject.
Fourteen years after the publication of Dr.Owen's epoch-making book, John Bunyan's _Holy War_ first saw the light.

Equal in scriptural and in experimental depth, as also in their spiritual loftiness and intensity, those two books are as different as any two books, written in the same language, and written on the same subject, could by any possibility be.
John Owen's book is the book of a great scholar who has read the Fathers and the Schoolmen and the Reformers till he knows them by heart, and till he has been able to digest all that is true to Scripture and to experience in them into his rich and ripe book.

A powerful reasoner, a severe, bald, muscular writer, John Owen in all these respects stands at the very opposite pole to that of John Bunyan.

The author of the _Holy War_ had no learning, but he had a mind of immense natural sagacity, combined with a habit of close and deep observation of human life, and especially of religious life, and he had now a lifetime of most fruitful experience as a Christian man and as a Christian minister behind him; and, all that, taken up into Bunyan's splendid imagination, enabled him to produce this extraordinarily able and impressive book.

A model of English style as the _Holy War_ is, at the same time it does not attain at all to the rank of the _Pilgrim's Progress_; but then, to be second to the _Pilgrim's Progress_ is reward and honour enough for any book.
