Module 4 — Theme 3: Judgment & Mercy
The Days of Noah
Jesus' own template for the end of the age — Matthew 24:36–44
📖 Module Overview
Modules 1 through 3 walked through the Flood from Genesis itself — the world that was, the ark and the waters, the rainbow covenant. This module turns to Jesus and asks a different question: what did He see when He looked back at Noah? In Matthew 24, on the Mount of Olives, the disciples ask Jesus when the end of the age will come. He answers many ways — and at the heart of His answer, He reaches all the way back to Genesis. The Flood, He says, is the pattern. What happened then is the shape of what is coming. This module sits with the eight verses where Jesus connects the two ages, and listens carefully to what He is — and isn't — saying.

The Passage in Full
Jesus' Days-of-Noah teaching is short — eight verses. But it sits at the center of the longest single discourse on the end of the age in the Gospels. Read it slowly before walking through the parts.
36 “But of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father alone. 37 For the coming of the Son of Man will be just like the days of Noah. 38 For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, 39 and they did not understand until the flood came and took them all away; so will the coming of the Son of Man be. 40 Then there will be two men in the field; one will be taken and one will be left. 41 Two women will be grinding at the mill; one will be taken and one will be left. 42 Therefore be on the alert, for you do not know which day your Lord is coming. 43 But be sure of this, that if the head of the house had known at what time of the night the thief was coming, he would have been on the alert and would not have allowed his house to be broken into. 44 For this reason you also must be ready; for the Son of Man is coming at an hour when you do not think He will.”
Part 1 — The Question Behind the Question
To understand what Jesus says in verses 36–44, we have to remember the question that started Matthew 24. The disciples have just walked out of the Temple, and Jesus has predicted that not one stone will be left on another. They wait until they are alone with Him on the Mount of Olives, and then they ask:
3 “Tell us, when will these things happen, and what will be the sign of Your coming, and of the end of the age?”
The disciples ask three questions woven into one — when will the Temple fall, what will be the sign of His coming, and what will be the sign of the end of the age. Jesus answers across the entire chapter. He talks about wars and famines and earthquakes. He talks about the abomination of desolation. He talks about false christs and false prophets. He talks about cosmic signs and the gathering of the elect.
And then, at verse 36, He pivots. After thirty-five verses of talking about signs, He says something startling:
The Pivot at Verse 36
“But of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father alone.”
After all those signs, Jesus says the day and hour are unknowable. Not "you will figure it out when the time gets close." Not "watch the calendar." No one knows. Not the angels. Not even the Son in His earthly ministry. Only the Father.
This is the question behind the disciples' question. They want a calendar. Jesus is about to give them something better — and harder. He is about to tell them how to live in the absence of a calendar. The Days-of-Noah passage is not Jesus answering "when?" It is Jesus answering "how should you be?"
Part 2 — “As in the Days of Noah” — The Marker Phrase
In verse 37, Jesus reaches all the way back to Genesis. "For the coming of the Son of Man will be just like the days of Noah." The Greek word translated "coming" is parousia (G3952) — "presence" or "arrival." In the ancient world, parousia was the formal word for the visit of a king or emperor to a city — the official, public, world-changing arrival of the sovereign. Jesus is not talking about a hidden coming. He is talking about His royal visitation, the day He comes back as King.
And He says that arrival will be just like the days of Noah. Not "similar in some ways." Not "with one or two parallels." Just like. Whatever Noah's generation looked like in the years before the flood, that is the picture of what the world will look like in the years before the Son of Man returns.
The Audience Already Knew the Backstory
When Jesus said "the days of Noah," every disciple sitting on the Mount of Olives already knew what He meant. They had grown up reading Genesis 6. They knew the world Noah preached to — the violence, the corruption, the “every intent of the thoughts of his heart was only evil continually” (Gen 6:5). They knew Noah preached for years while the world ignored him. They knew the door of the ark closed and the rain began.
Jesus does not have to explain any of that. He can use the phrase "as in the days of Noah" as shorthand because the picture is already in their minds. It should be in ours, too — which is why Theme 3 Modules 1, 2, and 3 sit underneath this module. If you have not walked through the Flood story for yourself, the weight of what Jesus is saying here is muted. He is making a one-line callback to a story we are meant to already know.

Part 3 — Eating, Drinking, Marrying — The Chilling Normalcy
When Jesus describes "the days of Noah" in verse 38, what does He list?
Four Verbs — None of Them Sins
Eating. Drinking. Marrying. Giving in marriage.
Notice what is not on this list. Jesus does not say "violence." He does not say "corruption." He does not say "every intent of every thought of every heart." Genesis 6 says all of that, and Jesus knows Genesis 6. But here, in this teaching, in this moment, He chooses four verbs that describe completely ordinary human life. Eating dinner. Drinking water. Falling in love. Building a family.
Why? Because the point Jesus is making is not about how wicked the world will be when He returns. He has made the wickedness point elsewhere (verses 10–12 of this same chapter, for one). Here, the point is different. Here, the point is the chilling normalcy.
The world Noah preached to was not just a wicked world. It was also a world where life kept going. Crops were planted. Babies were born. Weddings were held. People made plans. People retired. People assumed tomorrow would look like today. They were not wrong about wickedness — they were wrong about continuity. They believed the pattern would hold.
And that is what Jesus is saying about His own coming. The world will not look like a movie about the apocalypse. The world will look normal. Right up until it doesn't. People will be eating breakfast. People will be at the altar. People will be at the mill. And then the Son of Man will come, and the normalcy will end.
A Pause
It is easy to read the end-times sections of Scripture as if they describe a world we will recognize as obviously broken — sirens going off, sky turning black, panic in the streets. Jesus warns us that is not the only picture. The other picture is people eating sandwiches at their desks. People scrolling on their phones in line at a coffee shop. People kissing their kids goodnight. "They were eating and drinking, marrying and giving in marriage." Normalcy is not evidence that the time is far off. Normalcy was the last thing Noah's neighbors saw.
Part 4 — “The Flood Came and Took Them All Away”
Verse 39 lands hard:
39 “and they did not understand until the flood came and took them all away; so will the coming of the Son of Man be.”
Two things in this verse are worth slowing down on.
“They Did Not Understand”
The Greek word here is ginōskō — to know, to perceive, to come to understand. The verb form is the imperfect tense: they were not understanding, and they continued not understanding, all the way until the flood arrived.
This is not "they didn't get a chance to know." Noah preached. Genesis 6:9 calls him tsaddiq — righteous — and 2 Peter 2:5 calls him a "preacher of righteousness." For decades, while the ark was being built, Noah's life and message were a living warning. The neighbors saw the boat go up. They heard the preaching. They knew something was being said about coming judgment.
They did not understand not because they could not — but because they would not. They had information. They did not have hearts ready to receive it. Jesus is making a point: the issue is not data. The issue is posture.
“Took Them All Away”
The Greek word translated "took them all away" is
airō (
G142) — "to lift up, take away, sweep off, remove." It is the same word used when Jesus speaks of someone
taking up a cross. It is also the word used in John 1:29 for Christ who
takes away the sin of the world. Here, in verse 39, the flood is the subject and humanity is the object. The waters lifted. The waters carried. The waters removed.
The verse holds the moment in a single image: ordinary life — and then, suddenly, the wave. No second warning. No grace period. The door of the ark had already been closed (Gen 7:16, by God Himself). The rain came. The fountains of the deep broke open. And the world that had been eating and drinking the day before was simply gone.
Jesus closes verse 39 with the comparison: "so will the coming of the Son of Man be." Not "similar in spirit." So will the coming be. The same suddenness. The same lifting away. The same end of normalcy. The parousia of the King will not arrive on a calendar. It will arrive like a wave.
Then verses 40–41 paint the same picture in miniature: two men in the field, two women at the mill, ordinary daily work — and at the moment of that work, division. One taken. One left. The mechanics of who is taken and where they go are not Jesus' point here (and faithful Christians read those mechanics differently). His point is the suddenness. The division through the middle of normal life. The end of the assumption that tomorrow looks like today.
Part 5 — Watch Therefore: Two Words, One Posture
Having drawn the picture, Jesus closes with the command. And here, at the close, the Greek matters more than anywhere else in the passage — because Jesus does not just say "watch." He gives two different commands that work together. English flattens them. The original does not.
Command 1 — “Be on the alert” (v.42)
The Greek is
grēgoreite (
G1127) — "be awake, stay watchful, do not sleep." The same root gives us the proper name
Gregory, which literally means "watchful one."
This is a posture command. Don't drift. Don't go spiritually numb. Don't let the chilling normalcy of the world lull you into assuming the pattern will hold forever. Stay awake.
Command 2 — “Be ready” (v.44)
The Greek is
hetoimoi (
G2092) — "prepared, equipped, fitted out." It is the word used in Revelation 19:7 for the Bride of Christ who has
made herself ready for the Marriage Supper of the Lamb. It is the word used in Revelation 21:2 for the New Jerusalem coming down out of heaven,
prepared as a bride adorned for her husband.
This is a preparation command. Don't just stay awake — be equipped. Have your house in order. Have your relationship with God on right footing. Have the things that matter actually attended to, not just on a someday list. Be ready.
One is posture. The other is preparation. Watching without readiness is anxiety — the long, exhausting wait of someone with no plan. Readiness without watching is presumption — the comfortable confidence of someone who assumes they will see the threat coming and have time to react. Jesus says both. Stay awake and be equipped. The Christian life in the time before the parousia sits in the tension between those two words.
Verse 43 gives the picture: a thief in the night. If the head of the house had known at what watch the thief was coming, he would have stayed awake and locked the door. He didn't, so he didn't. Jesus is not saying His coming is a theft (He is the rightful King). He is saying the timing is like a thief's: unannounced, unknowable in advance, requiring constant readiness because there will be no specific heads-up.
A Pause
Both commands are present-tense imperatives in the Greek — keep on being on the alert; keep on being ready. This is not a one-time act. It is an ongoing way of living. The Christian life is not a single moment of preparation followed by years of distraction. It is a steady, daily posture — eyes open, house in order — held for as long as the wait lasts.
The Bigger Picture
Step back and look at what Jesus has just done. He has taken eight verses and connected the very beginning of the Bible to the very end of the age. The Flood becomes the prophetic template for the second coming. Noah becomes the prototype watchman. The chilling normalcy of the antediluvian world becomes the warning sign for our own.
And He has done this in a way that makes Theme 3 of this study guide weight-bearing for Theme 1. The end times in Theme 1 are not a separate teaching. They are a continuation of the pattern Noah saw. God warns. God waits. God provides a way of rescue. And then, at the appointed hour the Father alone knows, God acts. The flood was rehearsal. The parousia is the main event.
📍 What Module 5 Will Add
Module 5 (Salvation Through the Water) takes the same Flood story and looks at it through a different New Testament window — Peter's, in 1 Peter 3:20–21. Where Jesus uses the Flood as a template for His return, Peter uses it as a template for baptism. Same Flood, two different lenses, one unified theological picture: the water that destroyed a world is also the water that lifted a remnant to safety.
🙏 Reflection & Prayer
Jesus chose four ordinary verbs — eating, drinking, marrying, giving in marriage — to describe the days before the Flood. Where does the chilling normalcy of life today look most like those days? Where is the temptation strongest to assume tomorrow will look like today?
"They did not understand" not because they could not, but because they would not. Where in your own life are you tempted to listen to information about God without letting it change your posture? What would it look like to actually receive what you already know to be true?
The two commands — be on the alert and be ready — work together. Which of the two are you weaker on right now? Are you watching but not preparing, or preparing but not watching? What practical step would close the gap?
Noah preached for decades while the world ignored him. The Watchman principle (Theme 1, Module 4) lives inside the Days-of-Noah passage. Who in your life right now is in the position the neighbors of Noah were in — receiving information about God they have not yet acted on? How are you praying for them?
The Father alone knows the day and hour. Even Jesus, in His earthly ministry, did not. What does it mean for you to live in not-knowing as a Christian — to refuse the temptation of date-setting on one side and the temptation of indifference on the other?
If the parousia happened tomorrow morning while you were eating breakfast, what would you wish you had done today?
