A great treatise for the church militant. Gurnall uses his vast reading and his deep understanding of the Bible to impress upon the reader the duty and privilege of arming for spiritual battle. Not only does Gurnall have full command of a wide array of Biblical references--whether they be minute details from the Old Testament which he turns to profit or well-known passages--but he also uses illustrations drawn from his classical reading. All of his learning is turned Godward, to the great benefit of the reader.
The main downside of the book is it's length. A large portion of the book could have been cut without much loss. This may be one of those rare books that actually benefits from abridgment.
A few gems, among many:
On Christian courage: “[A]ll have a desire to be happy, but few have courage and resolution to grapple with the difficulties that meet them in the way to their happiness. . . The fearful are in the forlorn of those that march for hell (Rev. 21); the violent and valiant are they which take heaven by force: cowards never won heaven."
On spiritual-mindedness: "A gracious heart pursues earthly things with a holy indifference, saving the violence and zeal of his spirit for the things of heaven.He sets the former as if he used them not--with a kind of non-attendency; his head and heart is taken up with higher matters, how he may please God, thrive in his grace, enjoy more intimate communion with Christ in his ordinances; in these he spreads all his sails, plies all his oars, strains every part and power."
On the spiritual girdle: "It is not the many notions we have, but the establishment we have in the truth, that makes us strong Christians. . . A truth under dispute in the understanding is, as I may so say, stopped in the head; it cannot commence in the heart, or become practicable in the life. But when it passeth clearly there, and upon its commendation is embraced in the will and affections, then it is held fast, and hath powerful effects in the conversation."
On the sacraments: “The church is the garden, Christ the fountain, [and] every ordinance, as a pipe from him, to water the beds in his garden. And why? But to make them more abundant in the fruits of righteousness. . . Ordinances are as it were the exchange, where holy souls trade with God by his Spirit for heavenly treasures, from which they come filled and enriched with grace and comfort.”
On faith as the chief grace: "The whole army fight, yet the general or captain hath the honor of the victory ascribed to him. Alexander and Caesar's names are transmitted to posterity as the great conquerors that overcame so many battles, not the private soldiers that fought under hem. Faith is the captain grace."
