Joel: The Day of the LORD, Return & the Promise of the Spirit
A devastating plague becomes a call to return to the LORD, as Joel looks from present disaster toward the Day of the LORD, the outpouring of God’s Spirit and His dwelling among His people.
Welcome to Joel
Joel begins with devastation.
The land has been stripped.
Crops have failed.
Food is disappearing.
Worship at the house of the LORD has been affected.
And everywhere Joel looks, the effects of disaster can be seen.
At the centre of the opening chapters is a terrible locust plague.
Joel describes successive waves consuming what previous waves have left behind.
He calls elders, farmers, priests and all the inhabitants of the land to pay attention.
This is not something to forget.
They are to tell their children.
And their children are to tell another generation.
But Joel does more than describe a national catastrophe.
The disaster becomes the setting for a much larger prophetic message about: the Day of the LORD.
That phrase runs through the book.
Sometimes it feels frighteningly near.
Sometimes Joel’s vision stretches beyond Judah toward the nations and God’s future judgment.
Yet judgment is not Joel’s only message.
At the heart of the book comes an extraordinary invitation: “Return to Me with all your heart.”
And the reason Israel can return is grounded in God’s own character: “for He is gracious and merciful, slow to anger, and abounding in steadfast love.”
Then the book moves toward restoration.
God promises to respond to His people.
The land will again produce.
Shame will be removed.
And then Joel looks further ahead: “I will pour out My Spirit on all flesh.”
Sons and daughters will prophesy.
Old and young will receive God’s Spirit.
And: “everyone who calls on the name of the LORD shall be saved.”
Centuries later, when the Holy Spirit is poured out at Pentecost, Peter will stand before the crowd and say: “This is what was uttered through the prophet Joel.”
Joel therefore begins among ruined fields.
But its horizon eventually reaches all the way to Pentecost, the nations, the Day of the LORD and the presence of God among His people.
Before You Begin
You do not need this Overview in order to understand Joel.
And it is not intended to replace reading the book itself.
Joel is only three chapters in most English Bibles, so it can easily be read in one sitting.
As you read, begin by allowing the devastation of chapter 1 to be real.
Locusts have ravaged the land.
Agriculture has collapsed.
The people are mourning.
Priests are lamenting.
Do not rush too quickly past that historical setting in search of symbolism.
Then notice how Joel uses that disaster to direct attention toward: “the Day of the LORD.”
One question readers have long discussed is whether some of Joel’s descriptions continue portraying locusts in highly dramatic language or whether they shift to a human invading army.
There are reasons for different interpretations.
We do not need to settle every detail in order to follow Joel’s main message.
Something devastating has happened.
A greater day of divine judgment demands attention.
And God’s people are being summoned to return to Him.
It is also worth knowing that Joel does not tell us the king under whom he prophesied.
For that reason, the precise date of the book is debated.
Rather than building our interpretation upon a date Scripture does not give us, we can stay close to what Joel clearly tells us.
Above all, listen for what the book reveals about the LORD Himself.
The Message of Joel
Joel moves from present devastation to repentance, restoration, the promised Spirit and God’s final judgment of the nations.
Movement One – A Devastated Land & the Day of the LORD
Joel 1:1-2:11
What Happens Here
The word of the LORD comes to Joel, son of Pethuel.
Immediately he calls the elders and inhabitants of the land to listen.
Has anything like this happened in their days?
They must tell their children what has occurred.
A devastating sequence of locusts has consumed the land.
What one swarm leaves, another consumes.
The vine is ruined.
The fig tree is stripped.
Grain and drink offerings are cut off from the house of the LORD.
Farmers mourn.
Priests lament.
Joy withers with the harvest.
Joel calls the people to mourning, fasting and assembly.
Then he cries: “Alas for the day! For the day of the LORD is near.”
As chapter 2 begins, a trumpet sounds in Zion.
The Day of the LORD is again approaching.
Joel uses overwhelming imagery:
darkness,
gloom,
fire,
earthquake,
darkened heavens.
A vast advancing force fills the description.
And Joel asks: “For the day of the LORD is great and very awesome; who can endure it?”
What to Notice About God
Joel does not present the Day of the LORD as a vague religious idea.
It is the day of God’s decisive action.
That is why it cannot be treated lightly.
The LORD is not passive toward sin, rebellion or the affairs of nations.
His coming in judgment is described as overwhelming.
But the warning itself also creates an opportunity.
God is speaking before the final word has fallen.
He is summoning His people to respond.
A Thread to Follow
The Day of the LORD is much larger than Joel alone.
Other prophets use the same language.
Isaiah.
Amos.
Zephaniah.
Malachi.
And the New Testament continues using it.
The exact setting and emphasis must be read within each passage, rather than assuming every occurrence describes precisely the same historical moment.
But the thread is consistent: history is moving toward God’s decisive intervention.
Joel’s present crisis therefore becomes a window through which a much greater reality can be seen.
Pause & Notice
- What effects has the locust devastation had upon the land, the people and worship?
- Why does Joel call the community to remember the disaster and tell it to future generations?
- How does Joel’s language about the Day of the LORD enlarge the significance of the crisis before them?
Movement Two – Return to Me with All Your Heart
Joel 2:12-17
What Happens Here
After the frightening description of the Day of the LORD come two extraordinary words: “Yet even now…”
Judgment has been announced.
But the LORD says: “Return to Me with all your heart, with fasting, with weeping, and with mourning.”
Then Joel adds: “rend your hearts and not your garments.”
Outward signs of grief are not enough.
The people are being called to genuinely return to God.
And Joel gives the reason: “Return to the LORD your God, for He is gracious and merciful, slow to anger, and abounding in steadfast love.”
These words echo God’s revelation of His own character in Exodus 34.
Joel then asks: “Who knows whether He will not turn and relent…?”
There is no attempt to manipulate God.
The people are called to return because of who He is.
A trumpet is sounded.
A fast is consecrated.
The congregation is assembled.
Elders.
Children.
Even nursing infants.
Bridegroom and bride.
The whole community is summoned.
The priests are to weep and plead: “Spare Your people, O LORD.”
What to Notice About God
The call to repentance is grounded in God’s character.
Joel does not say: Return because you can force God to give you what you want.
He says: Return because the LORD is:
gracious,
merciful,
slow to anger,
and abounding in steadfast love.
That description is not invented by Joel.
It reaches back to God’s revelation of Himself to Moses.
The God calling His people home is the same God who has already made His character known.
A Thread to Follow
The words: “rend your hearts and not your garments” show us that biblical repentance cannot be reduced to outward religious performance.
The visible signs of mourning were meaningful.
But they were not meant to replace genuine return to God.
Joel therefore brings the issue to the heart.
Not merely: Look repentant.
But: Return to the LORD.
Pause & Notice
- What does God ask His people to do in response to His warning?
- Why does Joel emphasise the heart rather than outward signs alone?
- What aspects of God’s character give the people reason to return?
Movement Three – The LORD Responds & Restores
Joel 2:18-27
What Happens Here
The tone now changes.
The LORD responds with compassion for His land and His people.
Grain, wine and oil will again be provided.
Their reproach among the nations will be removed.
The destructive threat will be driven away.
The land is told: “Fear not, O land; be glad and rejoice, for the LORD has done great things!”
Animals need not fear.
Pastures will again become green.
Trees will bear fruit.
The people of Zion are called to rejoice in the LORD.
Rain returns.
Threshing floors fill with grain.
Vats overflow with wine and oil.
Then comes one of Joel’s best-known promises: “I will restore to you the years that the swarming locust has eaten…”
Within Joel, this promise has a very particular meaning.
God is speaking to the community whose crops have actually been devastated by the locust plague.
He promises renewed agricultural abundance following that devastation.
The people will eat and be satisfied.
They will praise the name of the LORD.
And they will know: “that I am in the midst of Israel, and that I am the LORD your God and there is none else.”
What to Notice About God
The greatest result of restoration is not merely fuller barns.
God says His people will know: “that I am in the midst of Israel.”
The restoration of the land demonstrates His covenant faithfulness and presence among His people.
The gifts point back toward the Giver.
A Thread to Follow
The phrase: “I will restore to you the years that the swarming locust has eaten” is understandably loved.
But we should let Joel define it before broadening it into a personal promise.
It is not a universal guarantee that every believer will receive back every opportunity, relationship, possession or year lost through suffering.
In Joel, God is promising restoration to this covenant community after this particular devastation.
That does not make the passage less beautiful.
It makes it more truthful.
The God who judged His people has not abandoned them.
He remains among them.
Pause & Notice
- What specific forms of restoration does God promise after the devastation?
- In its original context, what are the “years that the locust has eaten”?
- According to verse 27, what are the people ultimately to know through God’s restoration?
Movement Four – I Will Pour Out My Spirit
Joel 2:28-32
What Happens Here
Then Joel’s vision expands dramatically.
God says: “And it shall come to pass afterward, that I will pour out My Spirit on all flesh.”
The Spirit will not be described as resting only upon a few particular leaders.
Joel names:
sons and daughters,
old men and young men,
male servants and female servants.
They will prophesy, dream dreams and see visions.
Then come signs in heaven and on earth.
Blood.
Fire.
Columns of smoke.
The sun turned to darkness.
The moon to blood.
All before: “the great and awesome day of the LORD.”
And then: “everyone who calls on the name of the LORD shall be saved.”
What to Notice About God
God promises to pour out His Spirit.
And the breadth of the recipients is striking.
Age does not exclude.
Sex does not exclude.
Social position does not exclude.
God’s Spirit will be poured out across boundaries that might otherwise determine status within society.
This is God’s initiative.
“I will pour out My Spirit.”
A Thread to Follow
Here we do not have to speculate about how Joel connects with the New Testament.
Acts tells us.
On the Day of Pentecost, the Holy Spirit is poured out upon Jesus’ followers.
The crowd hears them speaking in other languages.
Some are amazed.
Others mock.
Then Peter stands and says: “This is what was uttered through the prophet Joel.”
He quotes this passage.
That gives us an explicit, Scripture-grounded connection between Joel and Pentecost.
Peter’s sermon then centres upon Jesus:
His death.
His resurrection.
His exaltation.
And the pouring out of the promised Holy Spirit.
Joel’s promise has entered the story of the risen Christ and the Spirit-filled church.
Pause & Notice
- Who does Joel say will receive God’s Spirit?
- What does the breadth of Joel’s list communicate about the promised outpouring?
- How does Peter explicitly use this passage on the Day of Pentecost?
Movement Five – The Nations, Judgment & the LORD Who Dwells in Zion
Joel 3:1-21
What Happens Here
Joel’s vision now turns toward the nations.
God speaks of restoring the fortunes of Judah and Jerusalem.
Then He gathers the nations for judgment in the Valley of Jehoshaphat.
The charge concerns how they have treated: “My people and My heritage Israel.”
They have scattered God’s people among the nations.
They have divided the land.
They have cast lots for people and traded human lives.
Tyre, Sidon and Philistia are specifically addressed for what they have done.
Then Joel reverses the language of peaceful agriculture: “Beat your plowshares into swords, and your pruning hooks into spears.”
The nations are summoned for judgment.
The harvest is ripe.
Multitudes fill the valley of decision.
The sun and moon are darkened.
The heavens and earth shake.
But in the middle of that terrifying picture: “The LORD is a refuge to His people, a stronghold to the people of Israel.”
The final verses describe blessing flowing from Zion.
Judah will be inhabited.
Jerusalem will endure.
God will deal with bloodguilt.
And the book ends: “The LORD dwells in Zion.”
What to Notice About God
Joel’s final chapter makes clear that the LORD is not merely concerned with what happens within Judah.
He judges the nations.
He sees violence.
He sees exploitation.
He sees what has been done to His people.
The nations remain accountable to Him.
But once again, the final destination is God’s presence: “The LORD dwells in Zion.”
The book that began with a devastated land ends with God dwelling among His people.
A Thread to Follow
Joel’s imagery of the Day of the LORD continues to echo through later Scripture.
The New Testament speaks repeatedly of God’s future judgment and the coming of Christ.
And Joel’s promise that: “everyone who calls on the name of the LORD shall be saved” appears again in Romans 10.
Paul quotes Joel while proclaiming salvation through calling upon the Lord in the context of faith in Jesus Christ.
So Scripture itself carries Joel’s language forward.
Acts 2 connects Joel with the outpouring of the Spirit.
Romans 10 takes Joel’s language of calling upon the LORD into the proclamation of Christ.
We do not have to manufacture the connections.
The New Testament gives them to us.
Pause & Notice
- Why are the nations being gathered for judgment in Joel 3?
- What does Joel reveal about God’s concern for violence and exploitation?
- How does the final declaration, “The LORD dwells in Zion,” complete the movement of the book?
See Joel as a Whole
Joel begins with devastation.
locusts → failed harvests → mourning → alarm
Then comes the warning: the Day of the LORD
But at the centre of the book comes an invitation: “Return to Me with all your heart.”
And from there the movement changes:
return → compassion → restoration → God’s presence → the Spirit poured out → salvation → judgment of the nations → the LORD dwelling among His people
Joel therefore does not move simply from disaster to prosperity.
It moves toward God Himself.
The people are called to return to Him.
Restoration shows that He is in their midst.
His Spirit will be poured out.
Those who call upon His name will be saved.
And the final sentence declares that He dwells in Zion.
Six Great Threads to Carry With You
1. The Day of the LORD Is Central
Joel repeatedly directs attention toward the Day of the LORD.
God will act decisively.
Human history is accountable to Him.
2. God’s Character Makes Return Possible
The call to return rests upon who God has revealed Himself to be:
gracious,
merciful,
slow to anger,
abounding in steadfast love.
Repentance is a response to the God who invites His people back.
3. God Desires the Heart, Not Religious Appearance Alone
“Rend your hearts and not your garments.”
Joel does not reject outward expressions of repentance.
He refuses to let them substitute for genuine return to God.
4. Restoration Promises Must Remain in Their Context
The restoration of crops and “the years that the locust has eaten” belong first to Judah’s actual devastation.
We should not turn them automatically into guarantees that every earthly loss in a Christian’s life will be restored.
5. God Promises His Spirit
Joel looks forward to an extraordinary outpouring: “I will pour out My Spirit on all flesh.”
Acts 2 explicitly identifies Pentecost with Joel’s promise.
6. God Is Lord of the Nations
Joel does not end with Judah alone.
The nations are summoned before God.
He judges injustice.
And the final vision belongs to the LORD who dwells among His people.
Where Joel Leads
Joel’s threads travel remarkably far through Scripture.
The Day of the LORD continues throughout the prophets and into the New Testament.
But the clearest bridge comes in Acts 2.
The Spirit is poured out at Pentecost.
Peter stands before the crowd.
And his explanation begins with Joel: “This is what was uttered through the prophet Joel.”
Peter then proclaims Jesus.
Jesus has been crucified.
God raised Him from the dead.
He has been exalted.
And Peter says that Jesus has: “poured out this that you yourselves are seeing and hearing.”
Joel’s promised outpouring of the Spirit is therefore placed explicitly within the story of the crucified, risen and exalted Christ.
Then another line from Joel appears in Romans: “Everyone who calls on the name of the Lord will be saved.”
Paul uses those words within his proclamation that: “Jesus is Lord.”
These are precisely the kinds of connections the Conservatory Library is designed to help us notice.
We do not need to search Joel for secret predictions hidden behind every locust or harvest.
Scripture itself shows us where to look.
Joel leads us toward:
the Day of the LORD,
the outpouring of the Holy Spirit,
salvation for those who call upon the Lord,
God’s judgment of evil,
and His presence among His people.
Before You Leave Joel
Joel begins with what has been eaten away.
Fields are ruined.
Vines are stripped.
Harvests have disappeared.
Joy itself seems to have withered.
Then comes the sound of alarm: the Day of the LORD.
But right at the point where the book could become only a message of judgment, God speaks: “Yet even now… return to Me.”
That may be one of the most important turns in Joel.
The God who warns is also the God who invites.
And Joel tells us why:
because He is gracious.
Because He is merciful.
Because He is slow to anger.
Because He abounds in steadfast love.
The book then keeps widening.
From ruined fields to restored harvests.
From Judah to all flesh.
From God’s people to the nations.
From a locust plague to the Day of the LORD.
From the promise of the Spirit to the declaration: “everyone who calls on the name of the LORD shall be saved.”
And finally: “The LORD dwells in Zion.”
Joel’s destination is not merely restored circumstances.
It is the presence of God.

- What have I discovered about God’s character as Joel moves from warning to invitation, restoration and future hope?
- How does the locust devastation provide the historical setting for Joel’s message about the Day of the LORD?
- What does “Return to Me with all your heart” reveal about the kind of repentance God desires?

Now Open His Word
This Overview was never intended to replace Joel.
And with only three chapters, you can read the whole prophecy in one sitting.
So open His Word.
Begin among the devastated fields.
Do not hurry past them.
Notice the locusts.
The farmers.
The priests.
The missing offerings.
The mourning.
Then listen for the Day of the LORD.
And when you reach: “Yet even now…” slow down.
Listen to God’s invitation.
Notice why Joel says the people can return to Him.
Then watch the book change.
Rain.
Crops.
God in the midst of His people.
His Spirit poured out.
Sons and daughters prophesying.
People calling upon the name of the LORD.
Nations gathered before God.
And finally: “The LORD dwells in Zion.”
When you later reach Acts 2, follow Joel there.
Let Peter show you the connection.
When you reach Romans 10, notice Joel’s words again.
Let Scripture interpret Scripture.
You do not need to turn every locust into a symbol.
You do not need to turn Judah’s restored harvest into a guarantee that every earthly loss will be returned to you.
Joel already gives us something much greater.
It reveals the God who calls people to return, promises His Spirit, saves those who call upon His name, judges evil and dwells among His people.
Because the purpose of the Conservatory Library is not merely to help you know more about Scripture.
It is to continually lead you back to Scripture – and through His Word, to know Him.
