A Lesson for the Reformed Student
Grace is not a loophole. It is a lifeline of the lovingkindness of God.
Illustration
My favorite illustration of how callous we have become with respect to the mercy, the love and the grace of God goes back to the second year of my teaching career when I was given the assignment of teaching 250 college freshmen a course in the introduction to the Old Testament. On the first day of class, I gave them their syllabus and I said, “Now, here’s how many tests we’re going to have, when we’re going to have them.” And I said, “You have three short little term papers, five pages each is all, little ones. The first one’s due at September the 30th when you come to class. The second one October the 30th and the third one November the 30th.” And I said, “You have to make sure that you have these papers done because if you don’t, unless you’re physically confined to the infirmary or in the hospital, or unless there’s a death in the immediate family, you will get an F on that assignment if you don’t have that paper here on time. Does everybody understand that?” “Yes.”
September the 30th came and 225 of my students came in with their term papers with them. There were 25 terrified freshmen who came in the back of the room trembling. “Oh, Professor Sproul, we didn’t budget our time properly. We haven’t made the transition from high school to college the way we should have. Please don’t flunk us. Please give us a couple more days to get our papers finished.”
I said, “Okay. I said, okay, this once. I’ll give you a break. I’ll let you have three more days to get your papers in, but don’t you let that happen again.” “Oh, no, no, no. Thank you so, so much.”
And then came October the 30th. This time 200 students came with their term papers. 50 students didn’t have it. I said, “Where’s your papers?” They said, “Well, you know how it is, Prof. It’s midterms and we had all kinds of assignments for other classes that were taken. It’s homecoming week. We’re just running a little behind. Please give us one more chance.” And I said, “You guys don’t have those papers. Do you remember what I said the last time? I said, don’t even think about not having this one in on time. And now 50 of you out there don’t have them.” “Oh yeah, we know.” I said, “Okay, it’s the last time. I’ll give you three days to get in your papers.”
And you know what happened? This really happened. I preached on this a few years ago and there happened to be somebody in the audience that was in that classroom and he hasn’t forgotten it. They started to sing spontaneously, 250 voices. “We love you prof. Oh yes we do.” And I was the most popular professor on that campus until November the 30th.
This time a hundred of them come with their term papers and 150 of them don’t have their term papers. And I watched them walk in as cool and as casual as they could be. And I saw one of them who was a Marine veteran. And he came walking in the room and I said, “Johnson, what? Where’s your paper?” He said, “Hey, hey, happy days. Hey, you know, don’t worry about it, Prof. I’ll have it for you in a couple days.”
I picked up the most dreadful object in a freshman’s memory, a little black book, and I opened up to Johnson. I said, “Johnson, you don’t have your term paper.” He said, “No.” I said, “F. Mickelson, where’s your term paper?” “Don’t have it.” “F. Pratt, where’s your term paper?” “Don’t have it. F.”
And then out of the midst of this crowd, somebody shouted what you know they would shout. “That’s not fair.”
And I turned around, I said, “Fitzgerald, was that you who said that?” He said, “Yeah, it’s not fair.” He said, “Right.” I said, “Weren’t you late last month with your paper?” He said, “Yeah.” I said, “Okay, I’ll tell you what I’m going to do. If it’s justice you want, it’s justice you will get.” And I went back and I changed his grade from October to an F. There’s this gasp in the room and I said, “Who else wants justice?” I didn’t get any takers.
You know, it was like a song similar to one out of My Fair Lady. I’ve grown accustomed to his grace. What had happened was the first time they were late, they were amazed by grace. The second time they were no longer surprised. They basically assumed it. By the third time, they demanded it and believed that grace was an inalienable right, an entitlement to which they all deserved.
“You know what you’ve done when you say that’s not fair is that you have confused justice and grace. The minute you think that anybody owes you grace, a bell should go off in your head to remind you that you’re no longer thinking about grace. Because grace by definition is something you don’t deserve. It’s something you can’t possibly deserve. You have no merit before God except demerit. And if God should ever, ever treat you justly outside of Christ, you will perish and your foot will slide in due time.”
Anytime there’s a group this large assembled, I don’t care for what reason, whether it’s a church service, whether it’s a Christian conference, I know that there are people in this room right now who are that far away from hell, and they’re assuming they’re not going to go there. But if there is a God, and there is, and if he is holy, and he is, and if he is just, and he is, he could not possibly be without wrath. And if you have not been reconciled through the blood of his son, the only thing you had to look forward to is his wrath, which is a divine wrath, which is a furious wrath, and is an eternal wrath because God must be regarded as holy by anyone who comes near him.
So my beloved, if you would come into the presence of God, consider the nature of the God whom you are approaching that you may come covered by the righteousness of Christ.

I remember a situation involving a friend of mine who was a high school principal. At his school, the student parking lot was a disaster—kids were parking on the grass, blocking fire lanes, and double-parking their friends. So, on the first day of the fall semester, he called an assembly for all the juniors and seniors who drove to school.
He said, “Listen, the rules are simple. To park on campus, you must have your permit displayed. If you park in a ‘No Parking’ zone, a fire lane, or take up two spots, you will be towed immediately at your own expense. No warnings, no second chances. Does everyone understand the law?” The students all nodded. They knew the rules.
For the first two weeks, everyone was perfect. But on a rainy Tuesday in September, three students—let’s call them Sarah, Mike, and Leo—were running late. They couldn’t find a spot, so they parked right in the yellow-lined fire zone next to the gym. According to the law, they should have been towed.
But the principal saw them from his window and felt a moment of compassion. He walked out, met them at the door, and said, “Look, I know it’s pouring and you’re late for a test. I should have your cars hooked up to a tow truck right now, but I’m going to let it slide. Just this once, I’m giving you a pass. Move them at lunch.” They were stunned. “Thank you, sir! You’re the best!” They were amazed by grace.
Fast forward to October. Word had spread that the principal was “chill.” One Friday, fifteen cars were parked in the fire lane. The principal saw them and called the students down. They started making excuses: “It’s game day,” “The main lot is too far.” Again, he sighed and said, “Okay, I’ll tell the tow company to stay away today. But don’t let this become a habit.” The students gave him a high-five and walked away laughing. They were no longer surprised by grace.
By November, the fire lane was packed every single morning. It had basically become the “Senior VIP Section.” One morning, the principal had finally had enough. He called the towing company and had every single car in the fire lane hauled off to the impound lot.
As the students came out at 3:00 PM and saw the empty pavement, they went ballistic. They marched into the office, red-faced and screaming. One girl, Chloe, yelled, “You can’t do this! This is so unfair! You didn’t tow us yesterday or the day before! You owe us a warning!”
The principal looked at her and said, “Chloe, did you park in a fire lane?” She stammered, “Well, yeah, but—” “And does the handbook say that results in an immediate tow?” “Yes, but you haven’t been doing it! It’s not fair that you’re starting now!”
The principal leaned back and said, “I see. You want ‘fair’? If it’s fairness you want, I have the security footage from Tuesday and Wednesday when you also parked there illegally. I’ll call the police right now and ensure you get the retroactive fines for those days as well. Since you want everything to be strictly ‘fair,’ let’s settle the whole debt.”
Suddenly, the room went silent. Chloe didn’t want “fair” anymore. She realized that for two months, she hadn’t been living under “fairness”—she had been living under mercy.
Part 1
One of the greatest spiritual dangers for people who grow up around the gospel is not open rebellion, but familiarity without fear. Over time, we begin to mistake God’s patience for approval, His silence for indifference, and His mercy for an obligation. We start to live as if grace were a permanent safety net that removes consequences rather than a rescue from destruction. But this confusion—between justice and grace—distorts how we understand both God and ourselves.
In the economy of God (God’s handling of creation), there are three distinct categories:
Getting the penalty we deserve
Not getting the penalty we deserve
Getting the favor we could never earn
As Reformed students, we know the definitions, but our hearts often struggle with the application. We tend to treat the Cross not as a rescue from certain death, but as a “parking pass” we’ve left in our lockers—something we assume will just work automatically whenever we get into a jam.
Let’s look a little closer.
Justice is God giving us what we deserve according to His holy law. God’s standard is not “mostly good” or “better than others,” but perfect righteousness. Every lie, every selfish thought, every act of pride or disobedience is treason against a holy God. If God dealt with humanity on the basis of justice alone, the outcome would be condemnation and eternal separation from Him.
Grace and mercy, on the other hand, is God giving us what we do not deserve. It is not God lowering His standards or ignoring sin. Grace and mercy exist only because justice has been fully satisfied in Jesus Christ. Christ did not cancel justice; He absorbed it. Grace is therefore not a loophole, not leniency, and not a divine shrug. It is a lifeline of lovingkindness.
The danger comes when we begin to expect the lifeline instead of clinging to it.
Because we embrace Reformed Theology as taught in Scripture, we already know God is sovereign, holy, and unchanging. His justice demands perfection, but His grace and mercy flow from His love through Christ to those He elects. But we humans have a sneaky way of twisting that.
Part 2
For believers—those truly saved by grace—God no longer relates to them as a judge condemning criminals, but as a Father training children. This is where many young Christians become confused.
For those whom God has saved through faith in Jesus Christ, the relationship between justice and grace takes on a specific character. Having been justified—declared righteous in God’s sight through the imputed righteousness of Christ—we will never face the eternal justice of God for our sins. Christ has borne that justice in full.
This is the foundation of our security.
However, our salvation does not place us outside the realm of divine discipline. The author of Hebrews is explicit:
For the saved, what feels like “unfairness” is actually fatherly love.
Therefore, for those of us who are saved, justice has already been satisfied. God will never pour out His wrath on us, because Christ already bore it fully. Every blessing we receive—life, forgiveness, patience, growth—is pure grace. Even discipline comes from love, not condemnation.
When believers encounter God’s discipline—whether through consequences for sin, prolonged suffering, or the painful exposure of hidden rebellion—we are prone to two opposite errors, both of which stem from confusing justice with grace.
The first error is the assumption that because we are saved, God will simply overlook our ongoing sin. We treat the cross like a parking pass we can forget in our locker. We assume that grace operates as a kind of spiritual insurance policy, covering all damages without raising our premiums. When consequences come—when the marriage fails, when the addiction is exposed, when the reputation is lost—we cry out with the students: “That’s not fair!”
But we have forgotten the nature of the God we serve. He is not merely gracious; He is holy. And His holiness demands that His children be holy.
The discipline we receive is not a revocation of grace but a fulfillment of it. Grace does not merely forgive our sins; it transforms us into the image of Christ. When God disciplines us, He is not being unfair—He is being faithful to the promise of grace, which promises not only escape from hell but conformity to heaven.
The Scriptures are clear:
Yet we boast nonetheless—not with our words, but with our expectations. We boast when we assume grace will always be there, waiting to catch us, regardless of how we treat it. We boast when we confuse the patience of God with the permission of God.
The second error is equally destructive: when we experience God’s fatherly correction, we assume that we have lost our salvation. We feel the weight of consequences and conclude that God has withdrawn His grace entirely. We forget that for the believer, there is a difference between punishment (the execution of justice for sin) and discipline (the training of a child for holiness).
Punishment is what Christ bore on the cross for our sins. Discipline is what the Father applies to our lives for our growth. Punishment seeks to satisfy justice; discipline seeks to produce righteousness. The believer never faces punishment again—the cross was sufficient. But the believer regularly faces discipline—because the Father is committed to our final glorification.
When the saved encounter God’s discipline, the proper response is neither presumption nor despair, but repentance and gratitude. We repent because we recognize that our sin has grieved the Holy Spirit who dwells within us. We are grateful because we recognize that the discipline proves our adoption:
We must never become so “accustomed to His face” that we forget the holiness of the One who gives grace. The cross was not a declaration that sin doesn’t matter; it was a declaration that sin matters so much that only the death of God in the flesh—the God-Man—could atone for it. When we treat grace casually, we trample the blood of Christ. When we treat discipline as abandonment, we doubt the promises of God.
When you feel “unfairly” disciplined, remember: You’ve become so accustomed to His gracious face that you’ve forgotten His blazing holiness. True justice would mean no second chances at all—we’d all perish instantly. But because you’re saved, discipline is grace refining you, proving you’re His (not illegitimate children, as Hebrews says). Don’t weaponize past mercies to justify ongoing sin; cling to the lifeline, repent, and grow. Without this, you risk hardening your heart, presuming on grace, and facing the consequences.
The believer’s cry should never be, “That’s not fair!” but rather:
We approach God knowing we bring nothing but our mess, and He is ready to cover it with Christ’s righteousness. But we also approach Him knowing that He will not leave us in our mess—He will sanctify us, however painful the process may be.
Sin isn’t a minor glitch; it’s rebellion against a sovereign God who elects us not because we’re worthy, but despite our total depravity. We’ve all broken God’s law—through lying, selfishness, cheating on that test, or putting idols like social media before Him—and justice would mean the full penalty: eternal separation from Him, wrath poured out without mercy. Yet God, for His glory, purposed before we even existed to save us from His wrath. He saves us to display His saving grace and His mercy, He passes over others—leaving them in their sin—to reveal His justice. All who are saved are elect—chosen by God before the foundation of the world. We’ve trusted in Christ and we’re secure in His grace. But that doesn’t mean a free pass to sin without consequences.
Part 3
Now we must turn to the second perspective: the fundamental difference between those whom God has saved and those who remain in their sins. This is the perspective that should drive our evangelism and deepen our gratitude, for it reveals what we have been spared and what others still face.
For the unsaved, the relationship between justice and grace is radically different. They have not been justified; they have not received the imputed righteousness of Christ; they remain under the wrath of God.
The word “remains” is crucial—it indicates a present, ongoing state.
The unsaved person experiences what we might call common grace: the patience of God that delays judgment, the rain that falls on the just and unjust, the conscience that warns of wrongdoing. But common grace is not saving grace. It is a temporary stay of execution, not a pardon. Every breath the unbeliever takes is a gift of mercy, but it is mercy with a purpose:
The unsaved person who experiences God’s patience and concludes that God has changed His mind about sin, or that God has lost His voice, or that God will always “come through” with mercy, has made a catastrophic error. They have mistaken the temporary delay of justice for the permanent absence of justice. God’s patience is not forgiveness. Delay is not dismissal. Every day without judgment is mercy offered, not justice removed. The unbelievers’ hearts become hardened with continued mercy as they indulge their sinful desires. When consequences do not immediately fall, they begin to believe they are safe. They treat the cross like something optional, something they can ignore now and deal with later.
That is a deadly mistake.
This is exactly what the college students did with their professor. By the third deadline, they assumed that grace was an inalienable right. When the professor finally applied the rules, they were shocked—not because the rules were new, but because they had ignored them. The unsaved person who dies in presumption will face the same shock, but without remedy.
The terrifying reality is that there are people in every assembly—every church service, every Christian conference, every youth group—who are “that far away from hell, and they’re assuming they’re not going to go there.” They have heard the gospel, perhaps even made a profession of faith, but they have never truly been converted. They are banking on God just overlooking their stuff because He’s “nice.” They are confusing grace with a handout.
For the saved, the security is absolute, but it is not based on their own righteousness. It is based on the finished work of Christ.
The word “securing” is past tense, complete, accomplished.
The saved person can never face the eternal justice of God for sin because Christ has already faced it. This is the foundation of our confidence. But this confidence must never become presumption. We do not continue in sin that grace may abound. We do not treat the cross as a parking pass. We do not grow “accustomed to His grace” in the sense of taking it for granted.
Instead, we grow accustomed to His grace in the sense of relying upon it more deeply. We recognize that every day we live is a day we do not deserve. Every prayer we offer is heard because of Christ’s merit, not our own. Every step of sanctification is empowered by the Spirit who was given to us as a seal of our redemption. We are secure, but we are secure in Christ—not in ourselves.
The distinction between the saved and the unsaved is not a theological abstraction; it is an urgent reality that should shape our lives and our relationships. If there is a God—and there is—and if He is holy—and He is—and if He is just—and He is—He could not possibly be without wrath. And if our friends, our family members, our classmates have not been reconciled through the blood of His Son, the only thing they have to look forward to is His wrath, which is a divine wrath, which is a furious wrath, and is an eternal wrath because God must be regarded as holy by anyone who comes near Him.
This is why we must never confuse justice with grace when we speak to the unsaved. We do not offer them a God who is “nice,” who will always let things slide. We offer them a God who is merciful, who has provided a way of escape through the penal substitutionary atonement of Christ. We call them to repentance and faith, not to presumption and delay.
Part 4
If you are a believer who is currently experiencing God’s fatherly discipline, hear this: your discipline is proof of your sonship, not evidence of your abandonment. The consequences you face for sin are not punishments—Christ bore your punishment. They are trainings, meant to conform you to the image of your Elder Brother.
Do not cry, “That’s not fair!” Instead, ask: “What is the Father teaching me? What sin is He exposing? What holiness is He cultivating?” Approach Him knowing you bring nothing but your mess, and He is ready to cover it with Christ’s righteousness. But do not ignore the discipline. Grace is not a loophole; it is a lifeline of covenant love, and the Father pulls on that lifeline to draw you to safety.
If you are a believer, hear this: your security is absolute, but your presumption is dangerous. Do not grow accustomed to grace in the sense of taking it for granted. Do not treat the cross as a parking pass. Do not assume that God will let you slide.
Instead, cultivate gratitude. Remember what you deserved. Remember what Christ bore. Remember that every breath is a gift of mercy. And let that gratitude drive you to holiness, for:
If you are not certain of your salvation, hear this: the patience of God is not the permission of God. Every day you remain unrepentant is a day of common grace. Do not presume upon tomorrow. Do not assume that God has changed His mind about sin.
We will all stand before the presence of God. Therefore, consider the nature of the God whom you are approaching. He is holy. He is just. He is wrathful against sin. And the only way to approach Him safely is covered by the righteousness of Christ. Come to Christ in repentance and faith. Receive His merit as your own. And you will find that grace is not a handout—it is a gift beyond price, purchased by blood, sealed by the Spirit, and kept by the power of God.
Part 5
Remember, grace is not a loophole. It is a lifeline of the lovingkindness of God.
The minute you think anyone, especially God, owes you grace, a bell should go off in your head to remind you that you are no longer thinking about grace. By definition, grace is something you cannot deserve, it cannot be owed.
Grace is not a standing offer that can be redeemed whenever someone feels like it. It is a gift. Those who presume upon grace—who assume God will always be patient, always overlook sin, always excuse rebellion—are not leaning on grace; they are rejecting it. When mercy is treated as an entitlement, only justice remains.
The same God who saves sinners through Christ will judge sinners who refuse Christ. No one will negotiate on that day. No one will argue that they were treated unfairly. Justice will be perfectly clear when it finally arrives.
For the saved, the lifeline is secure—we are held by the Father’s hand, and nothing can snatch us away. But the lifeline also pulls us upward from being dead and unresponsive in sin, toward holiness, through the sometimes-painful process of discipline. We must not resist that pull; we must actively respond in repentance and obedience, empowered by the Spirit, grateful that our Father loves us enough to correct us.
For the unsaved, the command is to repent. The patience of God has a limit, and that limit is the moment of death, or the moment of Christ’s return.
Let us never become so accustomed to grace that we forget what it cost. Let us never confuse justice with mercy, or mercy with entitlement. And let us approach the throne of grace with confidence—yes—but also with reverence, with gratitude, and with the sober recognition that the God who saves us is the God who would be justified in condemning us, were it not for the blood of His Son.
We must never become so familiar with God’s grace that we forget the holiness of the God who gives it. Grace is free to us, but it was infinitely costly to Christ. It does not make sin smaller; it proves how serious sin truly is.
Believers must never confuse discipline with injustice or mercy with permission.
Unbelievers must never confuse patience with approval or delay with safety.
Grace is not cheap, not automatic, and not owed. To forget this is to misunderstand grace. To remember it is to live in humble gratitude, holy fear, and joyful assurance.
“To him who is able to keep you from stumbling and to present you blameless before the presence of his glory with great joy, to the only God, our Savior, through Jesus Christ our Lord, be glory, majesty, dominion, and authority, before all time and now and forever. Amen.”
— Jude 24–25
