Luke 21:35Meaning & Commentary from the Church Fathers

The coming day will arrive without any visible signs, surprisingly and quietly, similar to a net that ensnares those who are inattentive. Some might analyze the phrase, ‘those who dwell on the face of the earth.’ This day will ensnare individuals who lead a relaxed and indifferent existence. These are exactly the ones who remain idle, becoming caught in the net.

Be vigilant, paying close attention to your hearts, so that you may be able to evade all upcoming trials. In the fifty-eighth chapter of the Gospel of Matthew, seek clarity on the verse, “Watch therefore, for you do not know at what hour your Lord will come.” Stand before the Son of Man, ready to meet Christ alongside the angels.

In these statements made by Jesus, an unfathomable divine glory was evident. Each listener sensed they were receiving more than mere warnings; indeed, it felt as if heaven and earth were poised to shift to ensure their realization. The God-Man continued by stating that no one knows the precise moment or hour of the end of the world (Matthew 24:36), not even the angels in heaven nor the Son Himself (Mark 13:32), but solely the Father. He added that when the Son of Man returns, it will mirror the days of Noah; people were eating and drinking and marrying right up until the day Noah boarded the ark.

The Lord emphasized the importance of vigilance, diligence, and fidelity among the disciples during these times. Therefore, be watchful, for you do not know the hour of your Lord’s return. Without Me, you are the keepers of the house; the householder remains alert, fearing that a thief might come and infiltrate his dwelling at any moment. Consider, moreover, your condition after My departure, akin to slaves entrusted with the care of the house during their master's absence. How tragic it would be for a servant if the master returns to find him squandering his resources carelessly; conversely, blessed is the steward who, upon the master’s return, receives no grievances, as all are content with his stewardship.

Among the teachings of Jesus Christ, which urged His disciples to remain vigilant in anticipation of the unpredictable return of the Son of Man, different Gospel writers have preserved unique insights. The Gospel of Luke offers a succinct exhortation on this matter and includes a reflection on the life and ministry of Jesus from His royal entry into Jerusalem to the Last Supper. Mark shares the parable of the servants alongside the gatekeeper awaiting their master. In contrast, Matthew presents four parables: the story of a homeowner at risk from a thief; the contrast between a faithful and an unfaithful servant (cf. Luke 12:39-48); the tale of wise and foolish virgins; the parable of the talents; and ultimately, the depiction of the severe judgment.

The exact timing of the event, including the day and hour, remains unknown to anyone but my Father; even the angels in heaven do not possess this knowledge. People will continue to live with the same indifference as they do today, just as in the days of Noah. They will partake in eating, drinking, and marrying, oblivious to the impending end. Just as the people in Noah's time failed to recognize the impending destruction until Noah entered the ark, bringing about their demise, so it shall be at the arrival of the Son of Man. Many will go about their lives without realizing that the moment to stand before God to account for their actions is upon them. Therefore, take heed to guard your hearts against excess and the worries of everyday life, so that day does not unexpectedly overtake you. It will arrive suddenly, like a trap, for all who inhabit the earth.

That day will arrive unexpectedly, serving as a time of reward for all devoted servants, while simultaneously being a moment of judgment for those who are not aligned with their true purpose and are unprepared for that significant day. To deeply instill the lesson of vigilance and faithfulness in their hearts, and to caution them more forcefully against the perils of a careless existence and the dimming of the flame of alertness, He shared two parables about the ten virgins and the talents (Matthew 25), notable for their simplicity and profound in their moral teaching.

Similar to a net used to capture fish, the fish remains unaware of the net's presence until it is suddenly ensnared. In the same way, the judgment of the Messiah will come upon those who live without caution, ignoring the signs of the times and their conduct.

When the precise moment of the Son of Man's return remains uncertain, it is vital for believers to maintain spiritual vigilance: watch, watch, and pray: for the hour is unknown. To engrave this call for spiritual alertness deeper into the hearts of His followers, the Lord related a parable. He depicted Himself as a master departing from His dwelling—the Church—to visit His Father in heaven, with plans to return and evaluate the servants’ stewardship. As a man leaving his home, He entrusted authority to His servants, assigning tasks while instructing the doorkeeper to remain watchful. This call to spiritual vigilance is a universal mandate for all of Christ’s disciples throughout all ages until the end of time: I say unto you, I say unto all, watch.
