This is an excellent extended exposition of 1 Corinthians 2:2, and is stimulating, stretching and edifying. In his introduction, J.I. Packer comments that, "Trusting, loving and following Jesus necessitates keeping the cross in view at all times. Our living Lord calls for what we may call cruciform discipleship, clear-headed, open-eyed, and whole-hearted." That is what Stephen Charnock seeks to promote in this book, with the blend of deep theological insight and warm pastoral application that is so characteristic of the English Puritans. To use a modern phrase, Charnock deep-dives into the nature of the atonement and what it means for us as Christians. He begins by considering what we know about Christ as crucified and contends that Christ, and especially in his death, should be the primary focus of a Christian's study and knowledge. Specifically in this section, he looks at the origin of Christ's death and the fact that it was ordered by God; at the person who suffered and died on the cross; and at the fruits and outcome of his death.
In the middle section of the book, Charnock unpacks what it means for Christ to be our Passover. He begins by proving that Christ is our Passover and does this by showing the resemblance between the paschal lamb and the Redeemer, and also by showing the resemblance to the effects of the Passover. Next, he moves on to demonstrate that this means that Christ was a sacrifice. He does this by explaining the purposes of the OT sacrifices, the fact that they all pointed to Christ, and the reasons that Christ specifically was fit to be a better and final sacrifice and priest for all who believe. Finally, he shows what it means for Christ to be a sacrifice for us, what was achieved by his sacrifice, and the practical application of these points.
The final section of the book is an extended consideration of the voluntariness and effectiveness of Christ's death, and why this is important and necessary. His central point is that Christ's offering of himself as our substitute was completely voluntary, was acceptable to the Father and satisfied his justice, and is efficacious for us by allowing God to be gracious and merciful, propitiating his wrath, expiating our sin, and allowing a righteousness to be imputed to us that is not our own. This brought glory to God and also confirmed both the covenant of redemption within the Godhead and the covenant of grace established with Abraham.
This book is strong meat, and J.I. Packer is right when he says that it can be hard work. Charnock is not as easily accessible as some of the other Puritans, but this book repays the effort.
A couple of good examples of Charnock's writing are below: "Why this voluntariness was necessary, on the part of the sacrifice itself. He was above any obligation to that work he so freely undertook for us. When 'he made himself of no reputation', it was a work of his charity, not of necessity; and he was bound in no other bonds, but those of his own love"
And again: "The satisfaction for sin was to be made by death, because man upon his revolt from God was by the immutable law bound over to death. Man could not satisfy the law but by death, and so must have lain under the bonds of that death for ever, and no convenient way could be found for his rescue, unless some one, who was not obnoxious to that penalty by nature, should suffer in his stead that death which he owed."
Apart from an overuse of commas, his writing has a kind of plodding elegance and exudes the comprehensiveness and attention to detail you expect from the Puritans. The other Puritan characteristic that he exudes is warmth and affection, both towards God and towards his fellow believers:
"How wonderful was the love of Christ! To accept so willingly of such hard conditions for us, and die so ignominiously upon the cross we had deserved! He knew the burden of sin, he knew the terrors of hell. Yet he did not shrink from the imputation of the one or the suffering of the other. It was not a willingness founded upon ignorance but upon a clear sighted affection. He was willing to be reproached that we might be glorified; he would be like to us that we might be confirmed to him; and took our human nature that we might in a sort partake of his divine."
And again: "How willingly then should we part with our sins for Christ, and do our duty to him! O that we could in our measures part as willingly with our lusts, as he did with his blood! He parted with his blood when he needed not, and shall not we with our sins when we ought to do so for our own safety as well as for his glory."
This is a book to read thoughtfully and with a pencil in hand, and I had to read many paragraphs several times before I understood them properly. It is also a book that will enrich the Christian's thinking on the sacrifice that Christ made on our behalf, and has deepened my appreciation and love for my saviour. I think that is exactly what Charnock would have wanted to achieve when he wrote it.
