"This work was first published in 1692, and makes for a great read still today both in addressing false teaching and in promoting the positive Reformation view of justification by faith alone in Jesus Christ and His imputed righteousness. This is one of the best works ever written on the subject. Here the central theme of the Christian gospel and the sure ground of the believer's hope is expounded with profound scriptural clarity. How the churches of today would benefit if pastors would preach this doctrine in contemporary dress as thoroughly, polemically, and winsomely as Keach did in his own day." Dr. Joel R. Beeke
