Law & Gospel: John Calvin has always held a special place among the writers I have read. His Institutes of the Christian Religion was one of the earliest substantial theological works I worked my way through, nearly forty years ago. It was not actually the first theology I had read, however. Before coming to Calvin, I had already spent considerable time reading Arminian writers, even making my way through Charles Finney’s entire Systematic Theology.
I no longer own most of the theology books I collected during those years. At some point, I began getting rid of anything that did not agree with my understanding of salvation. That seemed reasonable to me then, but now I see it as a mistake. Books do not have to agree with us in order to be useful. Sometimes the writers with whom we most strongly disagree help us recognize and express our own convictions more clearly.
Calvin was different. His writings remained with me, and I have gone back to them many times over the years. He possessed a rare ability to put great thoughts into memorable words, and there are passages in the Institutes that I have carried with me for decades. I have always been especially drawn to Book One, on the knowledge of God the Creator, and Book Two, on the knowledge of God the Redeemer in Christ. My first volume still contains my initials and the date January 1, 1987, written in the lower corner. That was something I used to do whenever I finished a book. Nearly forty years later, I am still returning to those same pages.
One passage in particular seems to open the door to the subject I want to consider here. It concerns the uncertainty that follows when the believer begins to look to his own works as the measure of his salvation. Calvin wrote: “For if they begin to judge their salvation by good works, nothing will be more uncertain or more feeble. From this it comes about that the believer’s conscience feels more fear and consternation than assurance. If righteousness is supported by works, in God’s sight it must entirely collapse.” (Institutes III.14.18)
Those words contain the heart of what I hope to consider. Before examining them more closely, however, I want to mention a modern expression of the very problem Calvin was warning against. While writing my recent post on repentance, I began looking into a book that I had heard mentioned many times over the years but had never personally read: John MacArthur’s The Gospel According to Jesus. I am aware of the controversy surrounding that book and the broader subject commonly known as lordship salvation. I do not intend to offer an extensive review of the book itself, nor to enter into every part of that controversy. I only want to consider one question that seems to lie near the heart of it: what happens when the believer’s obedience is made the measure or evidence by which he is expected to judge the reality of his salvation? Romans 4:4-5.
Before moving on, however, something must be said about the title itself. There is an audacity in that title that should not pass unnoticed. The Gospel According to Jesus is not the title of a modest theological proposal. It is a claim to speak with the authority of Christ Himself. It leaves the impression that what follows is not merely one interpretation of the gospel, but the gospel as Christ taught it, and that to resist the book’s conclusions is somehow to resist Christ. That is far too much authority for any human author to assume without the most careful scrutiny. If the teaching that follows turns the conscience away from Christ’s completed work and back toward the believer’s own repentance, obedience, submission, and perseverance, then the title has not merely overstated the case. It has placed the name of Jesus over a message that confuses law and gospel.
It sometimes seems that I write about the distinction between law and gospel more than almost anything else. That is not because I imagine that I understand it perfectly. The truth is that I see the confusion everywhere, and chiefly in my own heart. There is something in us that prefers law. Law gives us something to measure, something to perform, and something by which we may compare ourselves with others. Grace leaves us empty-handed before God and gives all the glory to Christ. Romans 11:6. That is why so much of Christian religion becomes wrapped in a web of conditions, duties, and qualifications. The language may still be the language of grace, but the conscience is being taught to live by law. And none of us is entirely free from that tendency.
This brings us back to Calvin’s warning. He does not say that judging salvation by works will give the believer a stronger assurance, provided those works are sincere enough or numerous enough. He says the opposite. Once salvation begins to be judged by works, everything becomes uncertain and feeble. The conscience is no longer resting in Christ. It is examining itself, weighing its obedience, measuring its progress, and wondering whether enough evidence can be found to support the hope that it is truly saved. Romans 8:33-34.
This is where the distinction between law and gospel becomes so important. The law tells us what God requires. It does not lower its standard because we are believers. It does not ask whether we have improved, whether our intentions are sincere, or whether we have obeyed more faithfully than someone else. It demands complete, inward, outward, and continual righteousness. The law does not divide obedience into acceptable portions or count sincerity as a substitute for perfection. Its demand remains whole. Once the law is made the measure of our salvation, it cannot assure us. It can only expose how far short we fall. Galatians 3:10.
We are very good at lowering the law when it is applied to ourselves. We would never say that we have obeyed perfectly, but we replace perfection with progress, sincerity, effort, or comparison. We persuade ourselves that we have obeyed enough to prove that our profession is genuine. But the law knows nothing of “enough.” It does not ask whether we are improving or whether our failures are less obvious than those of someone else. It demands complete obedience. If we offend in one point, we are guilty of all. James 2:10. The moment we make the law the measure of salvation, the law does not confirm us. It condemns us. II Corinthians 3:9.
The law does not come to negotiate with us. It does not soften its demands because we are weak, sincere, or distressed by what it reveals. It speaks with the authority of a holy God and finds us guilty beneath His perfect standard. Deuteronomy 27:26. But once our condition has been exposed, the law can take us no further. It cannot restore what sin has ruined or produce in us the righteousness it requires. It leaves us with a clear knowledge of what we ought to be and an equally clear knowledge that we are not that. Whatever hope remains must therefore be found somewhere beyond ourselves. Psalm 143:2.
But the law exposes something deeper than individual acts of disobedience. It reaches beneath our actions and reveals the corruption from which those actions proceed. Mark 7:21-23. We sometimes speak as though sin were merely a collection of wrong things we have done. But the problem goes much deeper than that. We do not become sinners because we sin; we sin because sin already belongs to our condition. Psalm 51:5. The law therefore does not find a basically good person who only needs a little correction. It finds a sinner who stands condemned before God and whose outward sins reveal what is already present within.
This is why the problem cannot be solved by improving a few parts of our lives. Nothing arising from a corrupt source can answer the demands of divine holiness. The law can only uncover that condition, pronounce judgment upon it, and silence every claim we might make for ourselves. Romans 7:18.
The sentence of the law is not that we should try harder and return later with better results. Its sentence upon sin is death. It does not treat our failure as a temporary setback or a weakness that can be overcome with enough effort. It declares us guilty before God and shuts every door through which we might attempt to establish a righteousness of our own. Romans 6:23.
The law is not the problem. It is holy, just, and good. The problem is the sinner who stands beneath it. The commandment enters, and sin rises against it. What this reveals is far more serious than ignorance or weakness. The sinner’s problem is not that he does not know what God requires, but that the heart itself resists the God who requires it. John 3:19-20.
This is where the full weight of the law must be allowed to remain. It does not merely show that we have failed to become better people; it brings us before the holiness of God and shows that we cannot stand there. Exodus 3:5. His holiness is not a standard we can gradually reach through greater effort, deeper sincerity, or improved obedience. It lies altogether beyond anything man can produce. The law therefore leaves us with no reduced standard to satisfy, no remaining merit to present, and no righteousness of our own to defend. It leaves no room for comparison, improvement, or excuse – only the verdict of a holy God. Genesis 18:27.
This is where the gospel speaks an entirely different word. The law has shown us what God requires and what we cannot produce. The gospel does not tell us to make another attempt. It points us to Christ. John 1:29. In Him, the righteousness demanded by the law has been fulfilled, and the judgment pronounced against sin has been borne. The sinner is not directed back to his own obedience, but to the obedience of another. Romans 5:19.
Here the difference between law and gospel cannot be missed. When the law is made the measure of salvation, it turns the sinner inward and demands an answer he cannot give. The gospel turns him outward to Christ and declares that the answer has already been given. Isaiah 45:22. Whenever assurance is tied to our condition, growth, or obedience, the conscience is left searching for evidence that can never be enough. The gospel ends that search by fixing the whole hope of the sinner upon Christ. I Corinthians 1:30.
The real question, then, is not whether obedience matters, whether repentance is precious, or whether the believer should desire to walk in ways pleasing to God. The question is where the conscience is sent when it asks, “Am I accepted before God?” If the answer is found in the quality of our repentance, the progress of our obedience, or the strength of our faith, then the law has been made the judge of our salvation, and uncertainty is unavoidable. Colossians 1:21-22.
Calvin was right. If we begin to judge our salvation by works, everything becomes uncertain and feeble. But when assurance rests upon the obedience, death, and righteousness of Christ, the conscience is given something firm upon which to rest. The law has spoken its verdict. The gospel has spoken Christ. MPJ
Postscript: “I hope I’m not overstating the position but this seems to underpin so much historical Puritan thinking too.” Brother, I think that may be the understatement of the year. It does not merely underpin Puritan thinking; it defines most of what passes for Christianity. Religion continually turns salvation into something man must establish, preserve, confirm, or prove by what can be found in himself. It is all about doing – doing enough to obtain something from God, doing enough to keep it, or doing enough afterward to prove that it was truly given.
One group emphasizes moral reform, another perseverance, another submission, another sacramental faithfulness, and another progress in sanctification – but the conscience is always sent back to the same questions: What have you done? What have you become? Is there enough evidence? They may insist that works do not save, but if works must finally prove that salvation is ours, then the conscience is still being judged by works.
That is the terrible contradiction: “You are saved by Christ alone, but you have no right to rest in Christ alone until your life proves it.” No wonder the flesh prefers such a system. It leaves us something to perform, something to measure, and eventually something in which to boast. The gospel leaves us with nothing but Christ.
Your caution about Calvin matters, because Calvin should not automatically be made responsible for Westminster, the Puritans, or modern lordship salvation. His statement in the Institutes shows that he understood something many of his supposed heirs seem to have forgotten: when salvation is judged by works, assurance collapses and fear takes its place.
Still, I am not turning Calvin into something he was not. He was a gifted writer and often a profound thinker, but he also taught things that were deeply confused and, at times, plainly wrong. The devotion shown to him by many of his followers can become almost embarrassing, as though questioning Calvin were somehow questioning the faith itself. Read him, appreciate what is good, reject what is not, and follow him only as far as Scripture permits. But why call ourselves Calvinists? Calvin did not die for us. Christ did.
Calvinism has become almost a theological badge for the serious-minded believer – the one who has moved beyond shallow religion, discovered divine sovereignty, and begun thinking carefully about Scripture. But being more intellectually satisfying than another system does not make it the gospel. If its final answer to the troubled conscience is still, “Look at your fruit, measure your progress, and prove your election,” then in what sense is it a better Christianity? It may be more sophisticated law, but it is still law. Marc
