Introduction

Throughout Scripture, God repeatedly calls His people to hear. Yet biblical hearing is never confined to the reception of sound or information. God's Word is intended to reach the heart, awaken understanding, produce a response, and ultimately reshape the way a person lives.

Scripture therefore uses surprisingly physical language to describe what can happen when that responsiveness is lost: hearts can become fat, thick, or covered, while God calls His people to circumcise and rend those hearts.

This three-part study follows that imagery from Isaiah into the teaching of Jesus, then traces the biblical vocabulary of the heart through the language of circumcision, rending, returning, and healing. Along the way, an important question emerges:

✨ What does God actually want to happen when His Word reaches a human heart? ✨

Part I.✨ The Thickened Heart: When Hearing No Longer Becomes Understanding

Matthew 13:10–13 becomes much more striking when read against Isaiah 6:9–10 in both the Masoretic Text (MT) and the Septuagint (LXX), because Matthew is not simply borrowing Isaiah's imagery. He is taking Isaiah's theology of hearing, seeing, understanding, and the heart and applying it to Israel's response to Jesus.

1. The setting in Matthew: the disciples ask the obvious question

After Jesus tells the crowd the parable of the sower, the disciples ask:

“Why do You speak to them in parables?”

Jesus' answer begins with a distinction between those who have been given the knowledge of the kingdom and those who have not. Then comes the remarkable statement:

“For whoever has, to him more will be given, and he will have an abundance; but whoever does not have, even what he has will be taken away.”

Then Jesus explains that His parables function simultaneously as revelation and concealment.

That is important. A parable does not automatically conceal the truth from everyone. The disciples hear the same words as the crowds. The difference is what happens after hearing. The disciples come to Jesus and ask. They pursue understanding. They receive further explanation.

That brings us directly into Isaiah's language of the heart.

2. The Hebrew is much more vivid than “calloused”

Isaiah 6:9-10 -  [The LORD] said, “Go and tell this people: “‘Be ever hearing, but never understanding; be ever seeing, but never perceiving.’ Make the heart of this people calloused [shāmen]; make their ears dull and close their eyes.

Otherwise they might see with their eyes, hear with their ears, understand with their hearts, and turn and be healed.”

The Masoretic Text literally: “Make fat [shāmen] the heart of this people.” It carries the idea of becoming fat, thick, rich, or prosperous. So when an English translation says, “Make the heart of this people calloused” it is interpreting the metaphor rather than reproducing its literal imagery.

Isaiah's sequence is fascinating: heart → ears → eyes

Make fat the heart
Make heavy the ears
Shut the eyes

And then: eyes → ears → heart → turning → healing

lest they see with their eyes
and hear with their ears
and understand with their heart
and turn
and be healed

The problem is therefore not intellectual deficiency. It is a failure of perception that reaches the heart. The heart is the organ of understanding, perception, volition, and response.

3. “Fat heart” is actually a powerful biblical metaphor

The Hebrew metaphor becomes especially meaningful when placed alongside other biblical uses of shāmen imagery. A “fat” heart is a heart that has become insulated from what it hears.

Truth enters through the ears → reaches the heart → produces understanding → produces turning. But the “fat” heart is resistant to that process.

Deuteronomy 32:15 - Jeshurun grew fat [shāmen], and he kicked; you grew fat, you bloated, and you became obstinate; and he abandoned God, his maker, and he scoffed at the rock of his salvation.

• Jeshurun means "upright one" and refers to Israel.

Abundance can produce self-sufficiency. The one who has been well supplied can become less receptive to the One who supplied him.

Psalm 119:70 - “Their heart is fat [shāmen] like grease, but I delight in Your law.”

The contrast is extraordinary: fat heart → diminished receptivity, versus delighting heart → receptivity to God's instruction.

“Calloused” communicates the effect, but “fat/thick heart” communicates the underlying metaphor.

4. The LXX makes an important interpretive move

The Greek Septuagint does not preserve the Hebrew imperative literally. Instead of “make fat” the LXX says: epachynthē. The Greek verb comes from pachynō, “to make thick, fat, or dull.”

So the LXX transforms the Hebrew's: “Make fat…” into: “The heart has become fat/thick…” That is a significant shift.

• The Hebrew can sound like a divine commission to Isaiah: Make fat the heart…
• The LXX describes the condition of the people: The heart of this people has become fat/thick…

It then says, “with their ears they heard heavily/dullly,” “they closed their eyes.” The LXX therefore makes the people's own condition and response much more explicit. And this is precisely the textual form Matthew follows.

Matthew 13:15 - “For the heart of this people has become thick/fat/dull.”

That is virtually the LXX's wording. The verb epachynthē is particularly important because Matthew does not say that Jesus is making their hearts hard in this verse, he says: their heart has become thick.

Thus the familiar English “calloused” is actually the endpoint of a much richer metaphor: fat → thick → dull → insensitive → calloused.

5. Matthew reproduces Isaiah's sequence

Isaiah says:

lest they see…
hear…
understand…
turn…
and be healed.

• The order matters: SEE → HEAR → UNDERSTAND → TURN → HEAL
• The heart sits at the center: SEE / HEAR → HEART → TURN → HEAL

That is extraordinarily close to Jesus' entire ministry. Jesus isn't simply dispensing information, He is bringing people to a point of recognition and response. And therefore the same revelation can produce radically different outcomes:

• Soft/receptive heart: hear → understand → receive → bear fruit
• Thickened heart: hear → fail to understand → remain unchanged

That is essentially the architecture of the parable of the sower itself.

6. This explains why Jesus says, “Whoever has…”

Matthew 13:12 - “Whoever has, to him more will be given…”

What does the person “have”? In the immediate context, it is receptivity to the kingdom's revelation. The disciples have heard Jesus' words and responded by coming closer:

Matthew 13:36 - “Explain to us…”

They don't possess some secret intellectual capacity that the crowd lacks, they just get curious and keep listening. They ask. They want understanding. Consequently, Jesus gives them more. The parable therefore becomes a kind of diagnostic instrument. It reveals what kind of hearer is listening.

And that is exactly what Isaiah anticipated.

7. The contrast between the disciples and the crowd is posture

Jesus does not tell His disciples: “You are smarter than they are.” He tells them: “To you it has been given to know the secrets of the kingdom…” The disciples' response to difficult teaching is: “Explain this to us.” That is radically different from: “I don't like this teaching, therefore I reject it.”

John 6 provides a beautiful parallel. Some disciples encounter a difficult saying and walk away. Peter, however, says, “Lord, to whom shall we go?” That is the difference between being confused and becoming closed.

A soft heart can say: “I don't understand.” A thickened heart says: “I don't understand, therefore I will not listen.” Those are not the same thing.

8. A fascinating agency question between MT and LXX

The MT's Hebrew is deliberately jarring: “make fat,” “make heavy,” “shut/close.” These are imperatives addressed to Isaiah. But the LXX changes the construction so that the people become the grammatical subjects: “the heart has become thick,” “they heard heavily,” “they closed their eyes.”

The LXX makes it apparent it is the listener who has determined the condition of their eyes, ears, and heart, NOT God.

And Matthew follows that LXX presentation. That matters when interpreting Matthew's parables. Jesus is not presenting Himself as arbitrarily preventing sincere people from salvation by hiding information from them. Rather, the parables expose and judicially confirm an already existing posture toward God's revelation.

✨ The same sun that melts wax hardens clay. ✨

The same proclamation of the kingdom produces: deeper perception in the receptive and deeper blindness in the resistant. Matthew's use of Isaiah therefore makes Jesus' teaching an act of both revelation and judgment.

9. “Calloused” can obscure something important

“Calloused” is a legitimate functional translation, but it can make us imagine something like deadened nerve endings. Isaiah's Hebrew picture is more textured:

• A “fat” heart: is a heart that has become thickened.
• Heavy ears: are ears that hear, but do not properly receive.
• Closed eyes: are eyes that possess the physical capacity to see, but refuse the perception that should follow.

And then Isaiah makes the tragedy explicit:

“lest they see… hear… understand… turn… and be healed.”

The tragedy is not that they lack access to revelation, they are surrounded by revelation, their problem is what revelation encounters when it reaches them. These people are keeping themselves from seeing, hearing, understanding, turning, and being healed.

10. And this makes the “calloused heart” connection to Jesus' disciples especially powerful

The disciples themselves repeatedly demonstrate that understanding is progressive. They hear Jesus. They misunderstand. They ask questions. Jesus explains. They hear again. They gradually begin to perceive.

That is exactly the opposite trajectory from Isaiah's thickened heart.

It suggests an important distinction: A disciple does not have to understand everything immediately. The critical question is whether he remains teachable.

The disciples' ignorance is not their defining characteristic. Their willingness to remain with Jesus long enough for ignorance to become understanding is. That makes Jesus' closing refrain especially fitting:

“He who has ears, let him hear.”

The issue is not possession of ears. It is what kind of hearing those ears produce in the heart.

Matthew's use of the LXX's (epachynthē) gives us the metaphorical key: the danger is a heart that becomes thick, increasingly insulated from revelation, until hearing no longer reaches understanding, so can no longer produces turning.

Perhaps the deepest contrast in Matthew 13 is not: people who know vs. people who don't know but people whose hearing remains open to formation vs. people whose hearts have become too thick to receive what they hear.

✨ Jesus' parables can simultaneously conceal and reveal: they do not simply transmit information; they expose the condition of the hearer. ✨

Part II. ✨ Cutting Away the Covering: Rend Your Heart and Circumcise It

There is a remarkably coherent biblical metaphor here: the problem of the “fat” heart is answered by God’s commands to cut, rend, and remove what has made the heart insensitive. The goal is not simply to make people hear more accurately, but to restore the heart's capacity to hear → understand → turn → obey → live.

1. The “fat heart” and the “circumcised heart” are almost opposite images

Isaiah 6 describes Israel's problem as a heart that has become thick/fat: shāmen - “to become fat, thick, rich.” The LXX renders this with: pachynō - “to make thick/fat; to make dull.” But Moses had already given Israel the remedy:

Deuteronomy 10:16 - “Circumcise therefore the foreskin of your heart, and be no longer stubborn.”

The metaphor is extraordinarily physical. Something is covering the heart that ought to be removed. And notice what immediately follows:

Deuteronomy 10:17 - “For YHWH your God is God of gods and Lord of lords…”

In other words, circumcision of the heart is connected with proper recognition of who God is and consequent allegiance to Him. It is not principally about becoming emotionally softer, it is about becoming responsive to God.

2. Jeremiah makes the same metaphor explicit

Jeremiah 4:4a - “Circumcise yourselves to YHWH; remove the foreskins of your hearts…”

And then comes the warning:

Jeremiah 4:4b - “lest My wrath go forth like the fire and burns, and there is no one who extinguishes it, because of the evil of your deeds.”

So there is a remarkable conceptual chain: heart covered → remove covering → restored responsiveness → covenant fidelity.

The biblical metaphor is therefore not: “Try harder to listen.” It is closer to: “Remove whatever has grown over the heart so that it can respond to God as it was designed to do.”

3. Then there is Joel's extraordinary command: “Rend your heart”

Joel 2:13 - “Rend your heart and not your garments…”

This is the language of tearing clothing in mourning. Joel essentially says: Don't just tear the garment, tear the heart. And the implication is profound. External religious action can occur while the interior person remains untouched.

Someone can tear his clothes, fast, weep, and participate in religious ritual, while the heart remains covered. God wants the heart itself opened. And notice what immediately follows: “Return to YHWH your God…”

There it is again: heart → turning → return. The same trajectory appears in Isaiah 6: see → hear → understand → turn → be healed.

4. “Rend” and “circumcise” are different metaphors accomplishing the same thing

They are not technically the same Hebrew image, but conceptually they converge.

• Isaiah 6 - Make thick/fat the heart → perception becomes dull.
• Deuteronomy 10 - Circumcise the heart → remove the covering.
• Jeremiah 4 - Remove the foreskin of the heart → stop resisting God.
• Joel 2 - Rend the heart → break open what is closed.

And eventually the prophets move beyond commands to God's promised intervention.

5. Deuteronomy actually anticipates the whole movement

After Israel's failure and exile, Moses says:

Deuteronomy 30:6 - “YHWH your God will circumcise your heart and the heart of your offspring, so that you will love YHWH your God with all your heart and with all your soul…”

That is fascinating because circumcision of the heart produces love, and that love produces covenant fidelity.

Deuteronomy 30:8 - “And you shall again obey the voice of YHWH…”

So we have: circumcised heart → love God → hear God's voice → obey → live. That is remarkably close to the Shema:

Deuteronomy 6:4-7 - ““Hear, O Israel: The Lord is our God, the Lord alone. You shall love the Lord your God with all your heart and with all your soul and with all your might. 

And these words that I command you today shall be on your heart. You shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise.”

But shemaʿ is bigger than the English “hear.” It encompasses hearing that results in heeding/obeying. So biblical hearing was never intended to terminate in auditory reception.

To truly hear God is to respond to what He says.

6. This illuminates Matthew 13 enormously

• Jesus says: “He who has ears, let him hear.”
• Then He quotes Isaiah: “Hearing you will hear and shall not understand…”
• But the positive possibility is: “hears the word and understands it…”

And what happens to that person? “He indeed bears fruit.” That is the key.

Matthew 13 isn't ultimately contrasting: people who receive information with people who don't receive information. It is contrasting: hearing that penetrates the heart and produces fruit with hearing that never produces responsive obedience.

The seed enters the soil, but the condition of the soil determines what happens next. So the biblical progression becomes:

HEAR → UNDERSTAND → RECEIVE → ENDURE → BEAR FRUIT

That is essentially Shema theology applied to the kingdom of God.

7. “Calloused” is a good translation-but not the whole metaphor

“Calloused” captures the functional result of the biblical imagery. A callus develops because repeated friction produces a thickened protective layer. That makes it an excellent metaphor for spiritual insensitivity.

But Isaiah's “fat/thick heart” and Deuteronomy's “foreskin of the heart” add another dimension: Something has accumulated over the heart. Something is preventing proper contact. Something needs to be removed.

So perhaps we can visualize the biblical movement like this:

• THICKENED HEART
• insensitivity
• hearing without receiving
• understanding fails
• no turning
• no healing

versus:

• RENDED / CIRCUMCISED HEART
• sensitivity
• hearing
• understanding
• turning
• obedience
• life / healing / fruit

8. A fascinating connection to the “two tables”

The biblical concept of the heart isn't detached from covenant obedience.

Jeremiah 31:33 - “I will put My law within them, and I will write it on their hearts.”

Compare that with Deuteronomy's movement from stone tablets to circumcised hearts. The issue isn't that God has failed to communicate His will, Israel already has the Torah, the problem is that the written command has to become internalized covenant allegiance.

That is why the New Covenant promise is not: “I will give them more information.” It is: “I will write My law on their hearts.” The problem was never principally insufficient revelation, it was insufficient responsiveness to revelation.

9. This also makes Jesus' “Why do you speak in parables?” answer more sobering

The disciples ask for explanation. Jesus gives it. That is a picture of a circumcised trajectory: “I don't understand. Teach me.” The resistant hearer encounters the same Jesus and essentially says: “I have heard enough.”

Thus the parable becomes a test of the heart.

The disciples' incomprehension is temporary because they remain relationally engaged with Jesus. The crowd's incomprehension can become judicial because they refuse to move toward Him for understanding.

That makes Jesus' words, “Whoever has, to him more will be given…” much more intelligible.

✨ The receptive heart becomes more receptive, the resistant heart becomes more resistant. ✨

10. The deepest irony: God keeps telling Israel to do what their heart was always supposed to do

God does not originally design Israel with a heart incapable of hearing. The repeated biblical command is: Hear. Listen. Love. Obey. Remember. Walk. Keep. Return.

So when the prophets speak of circumcising or rending the heart, they are not introducing a brand-new kind of spirituality. They are calling Israel back to the covenant responsiveness they were always supposed to possess.

Deuteronomy 6:4–5 - “Hear, O Israel…You shall love YHWH your God with all your heart…”

✨ The proper biblical response to hearing is obedience, and the proper expression of that obedience is love. ✨

Jesus therefore isn't changing the fundamental pattern when He says: “He who has ears, let him hear.” He is calling Israel back into the Shema. And Matthew 13's warning is essentially:

Don't possess ears and remain unable to hear. Don't possess Torah and remain unable to obey. Don't encounter the King and remain unchanged.

Part III.✨ Turn and Be Healed: The Destination of God's Desire

🌿 The stated divine desire is restoration

Isaiah 6:10 - “...lest they see with their eyes, and hear with their ears, and understand with their hearts, and turn and be healed.”

• The Hebrew verb for “turn” is (shûb), one of the great covenant words of the Old Testament. It means to turn back, return, come back. It is the language of repentance, restoration, and return to God.
• And “heal” is (rāp̄āʾ) — to heal, restore, make whole.

So the movement is: see → hear → understand → turn → heal.

The desired endpoint is healing. That is crucial for understanding both Isaiah and Jesus. The ultimate point of the passage is not blindness. It is the tragedy of refusing the very thing God desires: turning and healing.

1. The judgment is therefore not God's preferred endpoint

Isaiah's commission contains judicial language because persistent resistance to revelation eventually produces a condition in which further revelation becomes an occasion for greater blindness.

But the purpose expressed in the text is remarkably revealing: “lest…”

The grammar describes the result of their condition: they are not seeing, hearing, understanding, turning, and being healed. The tragedy is precisely that they are not reaching the destination God desires for them.

This fits the broader prophetic witness extraordinarily well.

Ezekiel 18:23 - “Have I any pleasure in the death of the wicked… and not rather that he should turn from his way and live?”

Ezekiel 18:32 - “For I have no pleasure in the death of anyone, declares the Lord YHWH; so turn, and live.”

• The repeated prophetic pattern is: turn → live, rather than: sin → perish because God delights in destruction.

2. God repeatedly describes Himself as waiting for the return

The Hebrew shûb is everywhere in the prophets.

Joel 2:12-13a - “Yet even now, declares YHWH, return to Me with all your heart. Rend your heart and not your garments.”

God doesn't simply want an external display of repentance, He wants the heart opened, the barrier removed, and the person to return. Then Joel gives the theological reason:

Joel 2:13b - “For He is gracious and merciful, slow to anger, and abounding in steadfast love…”

In other words: Why should you return? Because God wants you back.

3. This makes the “circumcision of the heart” especially beautiful

Deuteronomy 30:6 - “YHWH your God will circumcise your heart… so that you will love YHWH your God with all your heart and with all your soul, that you may live.”

Notice the endpoint again: circumcision → love → life. And this occurs in the context of returning after Israel's failure. So the metaphor of cutting away the heart's covering isn't ultimately about mutilation. It is about restoration of sensitivity.

God removes what prevents the heart from responding to Him. The “fat heart” becomes a circumcised heart. The insensitive heart becomes a responsive heart. The wandering person becomes a returning person.

And the returning person is healed and lives.

4. Jesus' use of Isaiah therefore carries an implicit invitation

Jesus says that Isaiah's prophecy is being fulfilled because: “this people's heart has grown dull…” But then He turns to His disciples and says: “But blessed are your eyes, for they see, and your ears, for they hear.”

What happens when people encounter the revelation of God?

The disciples come closer. The parable puzzles them, so they ask. They don't walk away because they don't understand. They return to Jesus for understanding.

And therefore their hearing becomes seeing. Their seeing becomes understanding. Their understanding produces discipleship. That is precisely the trajectory Isaiah says leads to healing.

5. Matthew's Gospel repeatedly shows Jesus doing exactly what Isaiah says God desires

This becomes almost impossible to miss when you step back. Jesus encounters:

• the sick → He heals them.
• the demonized → He restores them.
• sinners → He calls them to repentance.
• the lost → He seeks them.
• the blind → He gives sight.
• the deaf → He gives hearing.
• the spiritually blind → He gives understanding.

Matthew quotes Isaiah:

Isaiah 53:4 - “He Himself took our illnesses and bore our diseases.”

Jesus' ministry therefore embodies God's desire expressed throughout the prophets: restore what is damaged, recover what is lost, heal what is wounded, and bring back those who have wandered.

6. Even the word “repent” carries this direction

Jesus' opening proclamation is:

Mark 1:15 - “Repent, for the kingdom of heaven is at hand.”

The Greek is: metanoeite. But repentance in Jesus' proclamation is not simply psychological regret, it is a change of mind that produces a change of direction. That is remarkably compatible with Hebrew shûb.

• Shûb: turn/return.
• Metanoeō: change one's mind/perception and consequently one's direction.

Both point toward reorientation. And what lies beyond the turn? Healing. Restoration. Life.

7. There is an important distinction between judgment and desire

This helps resolve a tension in Isaiah 6. God can judge persistent resistance while simultaneously desiring the person's restoration. Those aren't contradictory.

• A physician can diagnose a disease accurately without desiring the patient's death.
• A judge can pronounce judgment without taking pleasure in destruction.
• A father can allow consequences while desperately wanting the child to return.

The prophets repeatedly hold these together: God judges evil because He is good but He does not desire the destruction of the person or people He is calling to repentance. The invitation underneath the judgment remains: Return.

8. And this makes “healing” larger than physical healing

The Hebrew rāp̄āʾ certainly can describe physical healing, but the prophetic usage frequently extends into restoration of the covenant relationship. The prophets capture this beautifully:

Jeremiah 3:22 - “Return, O faithless children; I will heal your faithlessness.”

That is almost a perfect commentary on Isaiah 6. Return → I will heal. The direction is unmistakable. God isn't saying: “Heal yourself and then return.” It is: Return to Me, and I will heal what is broken.

That is a profound biblical theology of salvation.

9. Back to the “fat heart”

The entire thread can now be seen as one continuous biblical metaphor:

Fat/thick heart
↓insensitive heart
↓hears without truly hearing
↓fails to understand
↓does not turn
↓does not experience healing.

God's remedy: Circumcise the heart
↓remove the covering
↓rend the heart
↓open it to God
↓hear
↓understand
↓turn/return (shûb)
↓be healed (rāp̄āʾ)
↓love God
↓obey
↓live.

That last sequence is especially important. God's desire isn't simply that Israel become better informed, He wants them alive.

10. The heart of Isaiah 6 is actually profoundly restorative

There is an irony in the English phrase “calloused heart.” We tend to hear it as: “These people are hopelessly hardened.” But the prophetic vocabulary gives us something more dynamic.

• A heart can become thick.
• A heart can be circumcised.
• A heart can be rended.
• A person can turn.
• And God can heal.

That means the prophetic warning itself functions as an invitation. “Your heart has become thick” is not the same statement as “your heart cannot change.” The very command to return presupposes that return remains meaningful.

And this is why Jesus can quote Isaiah 6 while simultaneously proclaiming the kingdom, healing the sick, forgiving sins, calling sinners, restoring outsiders, and inviting people to follow Him.

The final word is not: “Remain blind.” It is: “Turn—and be healed.” That is the direction of God's heart throughout the prophetic witness.

✨ The revelation that exposes our blindness is also the revelation that invites us out of it. ✨

The command to hear is ultimately a summons to respond, because God's purpose in bringing His Word near is not simply that we know what He has said, but that we return to Him, receive His life, and become whole.

1 Samuel 12:20 - Samuel said to the people, “Do not be afraid; you have done all this evil. Yet do not turn aside from following the Lord, but serve the Lord with all your heart.” 

Conclusion

The biblical picture that emerges is considerably richer than the idea of people who simply possess too little information.

Scripture portrays a human heart that can become thickened toward God's revelation—a heart that hears without truly hearing, sees without perceiving, and possesses the capacity to understand without allowing understanding to produce obedience.

Isaiah's imagery of the fat heart, Deuteronomy's command to circumcise the heart, Jeremiah's call to remove its covering, and Joel's command to rend the heart all address the same fundamental problem from different angles:

something has come between God's Word and the responsive heart He intended His people to have.

But the biblical story does not end with the diagnosis. The command to turn reveals God's purpose. The Hebrew shûb is fundamentally a movement of return: the wandering person comes back, the resistant person yields, and the person who has been facing away turns again toward God.

And what awaits that return? Isaiah says healing. Jeremiah records God saying, “Return, O faithless children; I will heal your faithlessness.”

Deuteronomy connects circumcision of the heart with loving God and living. Joel connects the rending of the heart with returning to a God who is gracious, merciful, and abounding in steadfast love.

That gives us the remarkable trajectory running through all three parts:

👂 Hear → ❤️ Receive → 🧠 Understand → 🔄 Return → 🩹 Be healed → 🌱 Live

Jesus' use of Isaiah 6 in Matthew 13 therefore carries both warning and invitation. The warning is that continued resistance can make the heart increasingly insensitive to what it hears.

But the invitation is embedded in the very language of hearing. “He who has ears, let him hear.”

The goal of revelation is not that people accumulate religious information. The goal is that the Word reaches the heart, the heart responds, the person turns, and God restores what has been damaged.

Ultimately, God's desire is not simply that His people hear Him correctly. He desires that they hear Him responsively—the kind of hearing Scripture calls Shema, hearing that becomes allegiance, love, obedience, and life.

The thick heart needs to be opened; the covered heart needs to be circumcised; the untouched heart needs to be rended; the wandering person needs to return. And beneath all of those commands stands the gracious purpose of God:

That His people be restored, that they respond, and that when they turn, they are healed.
