Here’s what nobody wants to admit: you might not be able to repent. Not because God is cruel. But because you’ve set up your own trap, and the door to escape locks from the inside. The Rambam is about to tell us something radical—there are 24 different ways to make repentance impossible for yourself. And the scariest part? Most of them don’t feel like sins at all. They feel reasonable. They feel like choices. So the question we’re asking today is this: if free will is real, if you can always choose to repent, then what does it mean when the Rambam says you can’t?

Chapter 4: When Teshuvah Becomes Impossible

The Rambam opens with a shocking claim: there are deeds so grave that God will not grant repentance. Not because God is vindictive, but because the sinner has placed themselves in a category where repentance is structurally impossible. Let’s be precise about what he means.

The first category—four severe sins—shows us the deepest betrayal: the one who causes masses to sin, the one who leads a colleague astray, the parent who sees his child going bad and stays silent, and most crucially, the one who says “I will sin and then repent.” This last one is the key. Why? Because repentance requires something essential: the recognition that you did something wrong. The person who says “I’ll sin now and fix it later” has already made repentance impossible. He’s shown that he doesn’t actually believe the sin is bad. He’s treating it like a debt he can pay off. That’s not repentance. That’s accounting.

Then comes the second category—five deeds that lock the paths of repentance. These are subtle. Separating yourself from community when they repent. Contradicting the Sages. Scoffing at mitzvot. Demeaning your teachers. Hating admonishment. Do you see what’s happening? The Rambam isn’t describing sins. He’s describing a posture. A way of being. Someone in this category isn’t refusing to repent. They’re refusing the very tools that would let them repent. You can’t be helped if you’ve decided help is beneath you.

The Rambam continues with five transgressions where complete repentance is impossible because you can’t make restitution. You cursed the masses—which people? You stole from a thief—what do you return? You ate from the poor without knowing who they were—how can you repay them? This category teaches something profound: repentance isn’t just internal. It requires the possibility of repair. When you’ve severed that connection, you’ve severed repentance itself.

Then five transgressions people regard as light—eating barely from someone’s meal, using a poor person’s pledge, looking at forbidden women, taking pride in someone’s shame, suspecting worthy people. The master principle here is blindness. These sins feel small because the sinner doesn’t see them as sins at all. And if you don’t see it, you can’t repent from it. You’re not rejecting repentance. You’re rejecting the very reality that would make repentance necessary.

Finally, five bad qualities difficult to abandon: gossip, slander, quick-temperedness, sinister thoughts, befriending the wicked. These aren’t transgressions. They’re patterns. They’re who you’ve become. And here’s the terror: you can’t repent from your own personality.

But then—and this is crucial—the Rambam adds a caveat that saves the entire teaching: “All of the above, though they hold back repentance, they do not prevent it entirely.” Even for these people, if they repent, they’re a Baal-Teshuvah. They have a portion in the world to come. What does this mean? It means repentance is never technically impossible. But it can become practically impossible if you’ve built a prison around yourself.

Chassidic Depth

The Tanya of Rabbi Schneur Zalman of Liadi teaches that every Jewish soul has a “divine spark” that can never be extinguished. Even when a person has buried it beneath layers of sin and self-deception, that spark remains. This is why the Rambam can say that repentance is “held back” but never “prevented entirely.” The spark is always there, waiting. The Lubavitcher Rebbe, in Likkutei Sichos, explains that the 24 obstacles are not walls—they are fog. They obscure the path, but the path still exists. The moment the fog lifts even slightly, the person can find their way back. This is why the Rambam lists these obstacles: not to discourage, but to make you aware of the fog so you can begin to see through it.

Chapter 5: Free Will Is Absolute

Now the Rambam pivots to something that seems to contradict everything he just said. Free will is absolute. Complete. No coercion. No destiny. “Each person is fit to be righteous like Moses, our teacher, or wicked, like Jeroboam.” You are not predetermined. You are not fated. You choose.

This is the pillar of Torah itself. If people are decreed righteous or wicked, what’s the point of law? What’s the point of mitzvot? What justice is there in punishment? “Shall the whole world’s Judge not act justly?” The Rambam is saying: God must grant free will. It’s not negotiable. It’s not optional. It’s the foundation of everything.

But here’s the objection everyone raises: what about God’s foreknowledge? If God knows what you’ll choose, have you really chosen? The Rambam’s answer is stunning. He says we cannot comprehend this. The measure of this question “is longer than the earth and broader than the sea.” God’s knowledge is not external to Him the way our knowledge is external to us. He and His knowledge are one. We cannot comprehend God’s essence, and we cannot comprehend His knowledge. So stop trying. “My thoughts are not your thoughts, nor your ways My ways.”

Then he gives us the only certainty we need: “Man’s actions are in his own hands and The Holy One, blessed be He, does not lead him in a particular direction or decree that he do anything.” That’s it. Whatever the metaphysical mystery is, the practical reality is clear. You are responsible. Your choices are yours.

Chassidic Depth

The Tanya teaches that even an evil impulse within a person, even the desire to sin, is ultimately rooted in the divine. Yet this rooting doesn’t negate choice. Rather, it means that the capacity to choose comes from God. God gives you the ability to choose, which is itself a divine gift. The Baal Shem Tov teaches similarly: even when you struggle, even when you feel enslaved by habit or desire, you have the power to return. The power is always there. It’s built into your soul. So free will isn’t just a legal concept for the Rambam—it’s a description of your deepest nature.

Chapter 6: When God Withholds Repentance

Now we arrive at the apparent contradiction. The Rambam quotes verses that seem to negate free will entirely. “And I will harden Pharaoh’s heart.” “I hardened the hearts of the Canaanites.” How do we reconcile this with everything we just said about absolute free choice?

The Rambam’s answer is surgical. When someone sins willfully and repeatedly, as a form of punishment, God may withhold repentance from them. Pharaoh chose to sin. He initiated the cruelty to the Israelites on his own. Then, as a judgment, God removed the possibility of repentance. Why? So that Pharaoh would face the full consequence of his actions. This isn’t God pre-determining Pharaoh’s evil. This is God responding to Pharaoh’s choice by removing the escape hatch.

But here’s the profound follow-up: why did God send Moses to tell Pharaoh to repent if God knew he wouldn’t? The Rambam’s answer: to demonstrate to all future generations what it means when God withholds repentance. So that people would see and understand: when the Holy One removes the capacity for repentance, it’s a sign of judgment. It’s a warning. It’s saying: you’ve gone too far.

The same pattern appears with Sichon, with the Canaanites, with the Israelites in Elijah’s era. Every single one sinned on their own initiative first. Then repentance was withheld. The order matters. It shows that God isn’t deciding people into wickedness. People are choosing it. And only after they’ve chosen it, only after they’ve rejected every natural inclination toward repentance, does God seal that choice.

The Rambam emphasizes one more time: regarding the prophecy that Egyptians would oppress Israel, God did not decree that a specific person would become a slave driver. Each Egyptian who harmed Israel chose to do so. God merely informed of the pattern. It’s like saying “there will be wicked people in the world”—no specific person is decreed wicked. Each one chooses it.

Chassidic Depth

This is where the Lubavitcher Rebbe’s teachings on Teshuvah become illuminating. In the Likkutei Sichos, the Rebbe emphasizes that repentance is not just about undoing the past. It’s about reconnecting. When someone is truly doing Teshuvah, they’re not just saying “I was wrong.” They’re saying “I’m returning to my source.” And that return is always possible. But—and this is the Rambam’s point—if you’ve convinced yourself that you don’t want to return, if you’ve hardened your own heart first, then God allows that hardening to be complete. He honors your choice. That’s actually the deepest expression of free will. God refuses to save you against your will.

What the Rambam Is Really Teaching

So what is the Rambam doing across these three chapters? He’s teaching us something that sounds paradoxical but is actually the deepest truth about repentance: repentance is simultaneously always possible and often impossible. Not because of God’s will. Because of yours.

Chapter 4 shows us the prisons we build for ourselves. Twenty-four different ways we can construct a situation where repentance is practically unreachable. But critically, the Rambam tells us these are not absolute. Even someone in these categories can repent. Chapter 5 confirms it: you have absolute free will. Nothing is decided for you. Chapter 6 then shows us the paradox: if you exercise your free will to harden yourself, if you choose sin repeatedly and close the door to repentance, then God honors that choice by making the door locked.

The master principle is this: God respects human freedom so completely that He will even allow you to trap yourself. He will not override your choice, even to save you. The price of free will is that you can use it to destroy yourself. But the flip side—and this is what saves everything—is that if you choose differently, if you take even the smallest step toward return, you are immediately helped. The moment you want to come back, the path opens.

Where This Meets Your Life

Consider someone who’s been gossiping for years. The Rambam says gossip is a bad quality difficult to abandon. Why? Because gossip doesn’t feel like a sin. It feels like connection. Like community. Like you’re bonding over truth-telling. So this person says “I’ll repent” but doesn’t actually believe gossip is wrong. The door to repentance isn’t locked by God. It’s locked because the sinner won’t acknowledge the lock exists.

Or consider someone who leads others astray—maybe a parent who models materialism and dishonesty to their children, or a mentor who subtly corrupts those they guide. They might say “I’ll fix it later” or “it’s not so bad.” But the Rambam says: you can’t repent from this because you won’t acknowledge it as sin. The repentance door is blocked by your own blindness.

Or consider someone who separates from community, who decides that everyone else is wrong, that the tradition is outdated, that wisdom comes only from their own thinking. When their community does repent, they’re not there. The path of repentance goes through connection. They’ve cut that connection. The door is locked from the inside.

In each case, the Rambam is saying: you have free will. You have the power to return. But if you use that free will to convince yourself that repentance isn’t necessary, that sin isn’t real, that community isn’t important, that wisdom should be disdained—then you’ve made repentance impossible. Not technically. But practically. You’ve locked the door.

The Rambam is telling us that free will is both your greatest gift and your greatest danger: God will allow you to trap yourself because respecting your freedom is more important to Him than saving you against your will, but the moment—the instant—you want to return, He is there to help.
