Nothing short of amazing!
Took a bit longer on this one, as the subject was both heady and the writing was dense. But man, old theologians got so much right, especially regarding the gospel and the clarity of growing in holiness by the gospel. Justified AND sanctified by grace through faith in Christ.
The law says do. The gospel says done.
Distinguishing between law and gospel not only increases your understanding of the scripture but assurance, holiness, and everything in between.
A must read for every Christian who seeks to mature in in their faith and move beyond milk to meat.

WOW, this was one of the most beautiful works I’ve read in a long time.

This book was so helpful to me in providing a more robust understanding of the law/gospel distinction and giving me language and categories to articulate it.

Disclaimer: I absolutely loved this book, but I am firmly Baptist so I am using “covenant of grace” slightly differently from Colquhoun and disagreed with most of chapter 2. Nevertheless, this was an excellent book and fully deserving of 5 stars.

I think one of the most helpful takeaways from this book is a clearer understanding of the law as a covenant of works and as a “rule of life in the hand of the Mediator.” The gospel is the fulfillment of the law as a covenant of works (under the Old Covenant), in the active and passive obedience of Christ.

Now under the covenant of grace (the New Covenant), the law is a rule of life (the moral law being summarized in the 10 commandments) that we obey (though imperfectly now) out of gratitude to God for the justification we have already been given freely by grace in the life, death, and resurrection of Christ, our Mediator.

Praise God for His amazing grace and mercy and for giving us the law as our guide unto Christ, Who perfectly obeyed it for us and gave us His righteousness that we might trust Him for our justification, walk in good works as fruit of that justification, and glorify and enjoy Him forever!

This was one of the most unexpectedly encouraging books I have read. Certainly one of my all time favorites. Understanding the difference and agreement between the Law and the Gospel is of the utmost importance for the Christian. Perhaps the most encouraging thing about this book was how often I was reminded that my standing before God is secured, not because of anything in me, but because of the perfect righteousness that is in the last Adam, the Lord Jesus Christ — that everything required of me in the Law is super-abundantly provided for me in the person of Jesus Christ!

A significant work on how Christians relate to the law. Colquhoun clearly articulates the need we have for holiness and the hope that we have as Christians in knowing that Christ perfectly upholds the law. A good source if you are looking to understand what role the law plays in our every day lives.

3.5, rounded to 4.

Good, but painfully repetitive.

A rather unspeakably beneficial book. Very technical, succinct explanations of the inner workings between the Law and the Gospel, how they serve one another, how they apply in their respective dispensations etc etc. I do say technical, but for even the less theologically minded folks this book is very digestible, as Colquhoun has a knack for simplifying otherwise complex ideas (Truths). Highly recommend.

Presenting a paedobaptistic understanding of the covenants in the beginning, Colquhoun goes on to articulate a beautifully clear and pastoral explanation of the Protestant understanding of the Law for 1. Declaring the holiness of God. 2. The sinfulness of man. 3. The necessity of Christ. 4. A rule of life for the Christian. He goes further to show the beauty of Christ sparking affections in our soul that pour out into obedient and good works.

It can be somewhat redundant, but in the best possible way. Colquhoun clearly parses both law and gospel and how they’re applicable for the believer. Very important and encouraging, and littered with Scripture on every page.

Any book you've read in the modern day about gospel-centered holiness or holiness that is empowered and motivated by the gospel is most likely drawing upon this wonderful work from the 1800s. I cannot recommend it enough! I believe every preacher/teacher needs to read it.

“The law and the gospel are in such harmony with each other as to have no divided interests.”

Some was good some I disagreed with. On the whole, it was written for a more literate audience than I am accustomed, which made some prolonged portions tiresome.

This is an in-depth study on the Law & the Gospel. It is long, and a little repetitive, but it will be worth your time. Solid work!

An excellent treatise on the law and Gospel, justification, sanctification. The first few chapters provide a helpful discussion of the Mosaic covenant and third use of the law for believers.

"Were we, indeed, to perform but a single act of obedience more than we owed to God, we would thereby merit some recompense from Him. But this is impossible for us ever to do. It is not the obedience even of a true believer that merits the blessings of salvation for him, but only the meritorious righteousness of Christ imputed to him" (pg. 80-81).

Colquhoun is also very helpful in distinguishing sanctification from justification and the proper role of good works in the life of believers. Good works are Gospel driven, sanctification flows forth from justification. This is very helpful for a proper understanding of both sanctification and assurance for believers.

"To pretend to sanctification, and then to rely on it for justification, is to derive the fountain from the stream, the cause from the effect, and so to invert the order of the blessings from salvation. It is necessary that our sins are forgiven, and our persons accepted as righteous in the sight of God, in order to our being capable of yielding the least degree of acceptable obedience to Him" (pg. 309).

Read Romans then read Galatians. They put it into puritan-esque language and you have John Colguhoun’s treatise on Law and the Gospel. I continually referred to it as law and grace because almost the entire book focuses on the difference between the two covenants. I do wish more had been emphasized on why particular acts belong to each one. Even still it , much like the Marrow controversy, attacks pharisaicalism and legalism as well as antinomianism. There is a small discussion at the end on the place of good works but I believe it is brief because it is sprinkled throughout. It is a reminder that obedience is required but never as a merit to eternal life. Much of it reads like Jonathan Edwards’ Religious Affections and that is a good thing.

This is a solid treatment on the Law/Gospel Distinction from a Reformed perspective. Which is really interesting because the Law/Gospel Distinction is often associated with Lutheran Theology, and Reformed Christians who use hold to a firm distinction between Law and Gospel are often described as "crytpo-Lutherans", but this work shows that the distinction does indeed have a place in Reformed Theology.

Really good. But the warning at the beginning, that sometimes things get redundant, definitely applies.

It’s sometimes dry, but the gospel message contained therein is still sweet.

Really helpful, relatively plain language, down-to-earth common sense application of “Marrow” theology. Very incisive on the distinction, difference, and agreement of the law and the gospel.

Final chapter, on good works, is a banger.

The contents of this book are incredible. It is imperative that every Christian understand the distinctions between law and gospel. However, this might be a difficult access point to these doctrines, simply because it was written in 1815. If you can handle something of that nature, give this a read!

Wow!! What an edifying read!

This book is heady but is a passionately delivered Gospel-centered treatise on the covenant of works and the covenant of grace that is meticulously cited with Scripture. John Colquhoun’s work should be the standard reference material regarding the study of the Law and Gospel for all Christians from lay-person to pastor.

Read all but two chapters. Quite an excellent little volume. Generally clear distinctions throughout. He presents a soft-republicationist view (though he prefers to use other language). Only complaint is that his style is repetitious; he makes his point several times, often becoming less clear the more he explains. Would recommend.

Law and Gospel

The law gospel distinction is vital in the understanding of the believer and the very essence of true religion. This book is one of the best I have ever read on the subject. Outstanding! Highly recommend!

Clear teaching on the distinction between the law in the covenant of works and the law of Christ in the covenant of grace. A distinction which affords help for understanding God’s relationship with men in history.
