"If I might read only one book beside the Bible, I would choose The Christian in Complete Armour."
- John Newton

"Gurnall's work is peerless and priceless; every line is full of wisdom; every sentence is suggestive. I have often resorted to it when my own fire has been burning low, and I have seldom failed to find a glowing coal upon Gurnall's hearth."
- C.H. Spurgeon

"A beautiful feature in Gurnall's book is its richness in pithy, pointed, and epigrammatical sayings. You will often find in a line and a half some great truth, put so concisely, and yet so fully, that you really marvel how so much thought could be got into so few words. Solid scriptural theology, like that contained in these pages, should be valued and studied in the church. Books in which Scripture is reverently regarded as the only rule of faith and practice - books in which Christ and the Holy Ghost have their rightful office - books in which justification, and sanctification, and regeneration, and faith, and grace, and holiness are clearly, distinctly, and accurately delineated and exhibited - these are the only books which do real good. Few things need reviving more than a taste for such books as these among readers."
- J.C. Ryle

"You could not buy a better work, nor get better value for your money."
