The book is an absolutely gem. To begin with, every Christian ought to know, if they do not now, that the Westminster Shorter Catechism is a marvelous summary of Christian doctrine. Knowing the Catechism gives the reader a solid foundation of Biblical, Reformed theology. But Watson has written, in a style easily understandable to those without formal theological training, to mine the gold that is contained in the Catechism. By that I mean that Watson’s book is highly experiential, a treasure of Reformed spirituality. I have worked my way through it by reading a portion each day for my devotional time It has been a tremendous blessing and encouragement to me. I highly commend it I would even compare its usefulness with Ryle’s Expository Thoughts on the Gospels.
