Vosotros pues también, estad apercibidos; porque á la hora que no pensáis, el Hijo del hombre vendrá.
Vós, pois, também estejais prontos; porque o Filho do homem virá à hora que não imaginais.
Vous aussi, tenez-vous prêts, car le Fils de l’ homme viendra à l’ heure où vous n’ y penserez pas.
Darum seid auch ihr bereit; denn des Menschen Sohn wird kommen zu der Stunde, da ihr's nicht meinet.
Gij dan, zijt ook bereid; want in welke ure gij het niet meent, zal de Zoon des mensen komen.
Anche voi siate pronti, perché nell’ora che non pensate, il Figliuol dell’uomo verrà.
Przetoż i wy bądźcie gotowi; bo o tej godzinie, o której się nie spodziewacie, Syn człowieczy przyjdzie.
Будьте же и вы готовы, ибо, в который час не думаете, приидет Сын Человеческий.
你們 也 要 預備；因為 你們想 不 到的時候，人 子 就來了。」

Scholars' Consensus
Commentators across traditions agree this verse issues a clear command: be ready. Gill notes that readiness here is "actually, in the exercise of grace and the discharge of duty" rather than merely a settled state. The Greek present imperative γίνεσθε calls for ongoing action, not a one-time decision but a continual posture. Lange connects this readiness to the preceding call to confidence in Luke 12:32: freedom from anxiety and watchfulness belong together. The "Son of Man" title echoes Daniel 7, pointing to the exalted figure who will come in judgment and salvation. Poole summarises the thrust: we must be "waiting for their Lord, that his coming may be welcome to them."
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Preterist interpretation: The coming refers to the destruction of Jerusalem in AD 70 (supported by Gill and Barnes, who note the imminent judgment within a generation).
- Futurist interpretation: The coming refers to the second coming of Christ at the end of history (emphasized by Geneva Notes and Matthew Henry).
- Both/and interpretation: The verse has multiple fulfillments: Jerusalem's fall, the final judgment, and even personal death (Gill mentions all three).
What is clear: Christians are called to live in constant readiness for the Lord's coming, whatever the specific timing.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Reference of the Son of Man's coming | The verse predicts a future coming of Christ for judgment and salvation. | Some interpret the coming as the destruction of Jerusalem in AD 70 (Gill, Barnes), while others see it as the second coming at the end of history (Geneva, Matthew Henry). A third position holds that it includes both events and also death. |
| Nature of readiness | Christians must be prepared through faith and faithful living. | Gill emphasizes imputed righteousness as the ground of readiness, while Lange and Matthew Henry focus on active watchfulness and good works. These are not mutually exclusive but are weighted differently across traditions. |
| Audience of the command | The command to be ready applies to all disciples. | Peter's question in v.41 raises whether the teaching is for the apostles alone or for everyone. Jesus' reply with the steward parable suggests special responsibility for leaders, but the command in v.40 is plural and inclusive. |
| The unexpected hour and human planning | The uncertainty of the hour should motivate, not paralyse, believers. | Some traditions stress that knowing the general time is impossible, so believers should simply live each day in readiness. Others point to signs of the times and argue that while the exact hour is unknown, the season may be discernible. |
Historical & Cultural Context
The setting of Luke 12:40 is a teaching on watchfulness. Jesus has just told a parable of servants waiting for their master to return from a wedding feast (vv.36-38). In the ancient world, wedding feasts could last several days, so the hour of return was uncertain. The command to have "loins girded" (v.35) refers to the practice of tucking long robes into a belt to allow quick movement, a picture of readiness for action. Lange notes this cultural detail: "The long garments of the Orientals had to be girt up if they were not to hinder them in walking and waiting." Verses 39-40 add the image of a thief breaking in at an unexpected hour, emphasizing the suddenness of the coming. Peter's question in v41, "Lord, are you telling this parable to us, or to everybody?", shows that the disciples sensed a special urgency for themselves as leaders. Jesus then expands the teaching to include faithful stewardship of others (vv.42-48). The original audience lived in a time of political tension under Roman rule and religious expectation that the Messiah would establish God's kingdom. This verse pressed them to live with anticipation, not passivity. Early Christian communities used this teaching to sustain hope through persecution, reading the "coming of the Son of Man" as both a future event and a present call to faithfulness.
Textual Notes

Reception History
This verse has been a central text for Christian teaching on watchfulness. The early church read it as a call to persevere under persecution, expecting Christ's imminent return. In the medieval period, it was linked to the "Four Last Things" and used in preaching to awaken spiritual urgency. Reformation commentators like Matthew Henry and Gill stressed both the imputed righteousness that makes believers ready and the active obedience that follows. Modern preaching often uses the verse to counter date-setting and to encourage persistent faith. The imagery of the thief and the unexpected hour appears in hymns and liturgies that keep the congregation looking forward to Christ's coming.
Preaching This Verse
Three-point outline
- The command is present and continuous. "Be ready" (γίνεσθε ἕτοιμοι) is a present imperative, not once but always. Gill emphasises actual readiness in the exercise of grace and duty.
- The coming is certain but unknown. "The Son of Man is coming." The title points to Christ's authority and role as judge. Yet the hour is hidden from us, just as a thief's visit is unexpected (v.39).
- Readiness changes how we live today. As Poole writes, uncertainty of the time pressures us toward a "sober, heavenly, and holy life." Waiting is not passive but active, girded loins and burning lamps.
Five-point outline
- "Therefore", the connecting word. Jesus ties readiness to the parable of the watching servants (v.36-38). Our freedom from anxiety (v.32) leads to alert service.
- "You also", the personal address. The emphatic ὑμεῖς ("you yourselves") means this command hits each hearer directly. Peter's question in v.41 asks whether it applies to leaders or everyone; Jesus answers with the steward parable.
- "Be ready", the posture. The Greek adjective ἕτοιμοι means prepared, at hand. The verb γίνεσθε ("become, keep on being") implies growth and maintenance, not a one-off decision.
- "The Son of Man", the one we await. This title, from Daniel 7:13-14, identifies Jesus as the end-time ruler who receives an everlasting kingdom. His coming is both a comfort and a sobering call.
- "An hour you do not expect", the test of faith. Uncertainty strips away presumption. Every moment becomes an opportunity for faithfulness. As Luke 21:34 warns, we must not let life's cares weigh us down and make the day catch us off guard.
Illustration hooks
- A family who keeps their home tidy not because they expect company tomorrow, but because they always want to be ready for unexpected visitors. Readiness becomes a habit, not a panic.
- A student who studies every night rather than cramming before an exam with an unknown date. The discipline of daily preparation removes fear of the test day.
- A night shift security guard who stays alert even when the supervisor has not visited in months. The habit of watchfulness keeps him effective at all times.
Questions your congregation is asking
- How can I be ready for Christ's return when I don't know when it will happen? Does this just make me anxious?
- Is readiness the same as being perfect? What if I feel far from ready?
- Does the unexpected hour mean I should stop making plans for the future?
Leading a Discussion
This passage speaks to the tension of living between Christ's first and second coming. We know the end of the story, but we do not know the timing. Jesus calls us to a readiness that shapes our daily priorities and relationships. The small group should focus on what readiness looks like in practice, not just in theory.
Discussion questions
- Read Luke 12:35-40. What images does Jesus use to describe readiness? How would these pictures have made sense to his original hearers?
- Verse 40 begins with "Therefore." What does this word connect back to? How does Jesus' teaching about God's care (vv.22-32) relate to the call to watch?
- In your own words, what does it mean to "be ready" for the Son of Man's coming? Is readiness a feeling, a belief, or an action? Defend your answer from the text.
- The Greek verb for "be ready" is a present imperative, it implies continuing action. Why is that important? How does ongoing readiness differ from a one-time decision?
- Peter asks in verse 41 whether the parable is for the disciples or for everyone. How does Jesus' answer (vv.42-48) apply to different people differently? What does it mean for you personally?
- Read Matthew 24:44. How does this parallel help us understand the seriousness of Jesus' command? What consequences does Jesus describe for those who are not ready?
- What is one specific way you could live more expectantly this week? How can the group support each other in that commitment?

What the Commentators Say
5 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Be ye therefore ready also - It is pretty evident that what is related here, from Luk 12:35 to Luk 12:49 , was spoken by our Lord at another time. See Mat 24:42 (note), etc., and the notes there.
Barnes' Notes on the Bible Protestant 1832
Barnes offers no fresh comment on this verse. Instead he directs the reader to his own earlier notes for the meaning of the second watch period and the broader command to remain watchful.
Geneva Bible Notes Reformed 1599
The Geneva note stresses that Christ's return will be utterly unforeseen. Since no one knows the hour, every believer must remain in a constant state of readiness, not just when it seems likely. The warning is practical: the danger lies in being caught off guard when the Son of Man appears.
Gill's Exposition of the Bible Baptist 1748
Gill stresses that readiness for Christ's coming is not merely a habitual state but an active preparation involving Christ's imputed righteousness and imparted grace. This readiness, shown in good works, prepares believers for either the destruction of Jerusalem or their own death and judgment, which come at an unexpected hour.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry points out that Jesus argues from the greater to the lesser: if God gave you life and a body, He will certainly provide the smaller things that sustain them. Worrying is pointless because it cannot accomplish anything, and it reveals a lack of trust in the Father who already knows your needs and values you far more than the birds or flowers.
