Mark 13:35 tells believers to stay alert and ready because they cannot know when Jesus will return. Jesus gives the command to keep watch, and the reason is that the timing of his coming is hidden from everyone. He speaks these words to his disciples on the Mount of Olives, during a private conversation about the end of the age and the destruction of the temple.
Watch therefore, for you don’t know when the lord of the house is coming, whether at evening, or at midnight, or when the rooster crows, or in the morning…

What Mark 13:35 Means
The verse begins with the word “therefore,” which links it to the parable just before it. A man goes on a journey, leaves his servants in charge of their tasks, and tells the doorkeeper to stay awake. The servants do not know which hour their master will walk back through the door, so the instruction is to keep alert for whenever he arrives.
Jesus then lists four possible times: evening, midnight, the crowing of the rooster, and morning. These are the ordinary divisions of a night in the ancient world, with the rooster marking the late-night watch before dawn. The list does not give a schedule. It shows that the master could arrive at any point, so readiness has to cover the whole night.
The verse does not promise a date, and it does not tell believers they can work out the timing. It also does not say that Jesus is slow to return. It simply says that the moment is unknown and that the right response is to stay watchful rather than careless or asleep.
The Context of Mark 13:35
Mark is generally regarded as the earliest of the four Gospels, traditionally attributed to John Mark, a companion of Peter. He wrote a brisk account of Jesus’s ministry for a community that was likely facing persecution, and Mark 13 is often called the “little apocalypse” because of its warnings about upheaval before the end.
Just before verse 35, Jesus says that no one knows the day or hour, not even the Son, but only the Father. The parable that follows then shows what faithful waiting looks like in practice. Because the verse sits inside that teaching, it reads less as a call to anxious speculation and more as a call to steady faithfulness while the master is away.
Key Phrases in Mark 13:35
1 Thessalonians 5:2
For you yourselves know well that the day of the Lord comes like a thief in the night.
(WEB)
Paul uses the same image of a thief in the night to describe the Lord’s day, reinforcing the theme that the timing is unexpected and that believers should not be caught unprepared.
Matthew 24:42
Watch therefore, for you don’t know in what hour your Lord comes.
(WEB)
Matthew records a close parallel to this teaching, where Jesus urges his disciples to stay awake because they do not know the day their Lord is coming, showing the command appears in more than one Gospel.
A Short Prayer From Mark 13:35
Lord Jesus, you know the hour of your coming, and I do not. Keep my heart awake and attentive, so that I am not lulled into careless living by the busyness of my days. Help me to do the work you have given me with faithfulness and love, trusting you with what I cannot see. When you come, whether at evening, midnight, or morning, let me be found watching and ready to welcome you. Amen.
