Bible in 5: Mark 13:28-37 — Keep watch, there's work to do
Jesus doesn't hand over a date for the end; he hands each servant a task and a lit lamp.
Not even the Son knows the day. Mark 13 says so in the Olivet Discourse, and the conclusion isn't a calendar: the house has work to do.
"But concerning that day or that hour, no one knows, not even the angels in heaven, nor the Son, but only the Father. Be on guard, keep awake. For you do not know when the time will come" (Mark 13:32-33, ESV).
One verse earlier, Jesus had said what holds everything else up: "Heaven and earth will pass away, but my words will not pass away" (Mark 13:31, ESV).
«Keeping watch is not scanning the horizon with your phone in your hand»
A fig tree, a hidden date and a house with assignments
The question is born in private. Peter, James, John and Andrew want to know when it will all happen, after hearing that the temple would be completely torn down (Mark 13:1-4).
The answer fills the whole chapter. It warns of persecution and betrayal, names the abomination of desolation and announces the Son of Man coming with glory. At the end, it sorts everything into three steps: the fig tree teaches us to read the season (13:28-30); his word stands firm when heaven and earth are gone (13:31); and the day with no date leaves the house with an assignment (13:32-37).
The book is attributed to John Mark, a helper of Paul and a close associate of Peter. Britannica notes that he wrote for readers outside Judaism: he explains customs and translates Aramaic sayings. Most likely they lived in Rome, with persecution on top of them and the war in Judea ahead of them.
What it reveals about God and the gospel
No one arrives at the hour of the last day with calculations or maps. It is reserved, and the only one who knows it is the Father.
That the Son himself admits this is more unsettling than any sign. When he became flesh, he also took on the limits of a servant (see Philippians 2:7-8), without ceasing to be who he is. That doesn't lower him: it measures how far his obedience went. The one who will come with glory is the same one who walks toward the cross.
In the parable, the master leaves and doesn't leave the house empty. He gives each one the key and the job, and puts a doorkeeper on guard at the door (see Mark 13:34). He assigns the task; nobody makes it up. And nobody gets to be a spectator.
There is the gospel: he is the owner, and those who wait are his own, not employees on probation. Waiting isn't taking an exam: it's living knowing that his word outlasts the universe.
Keeping watch is not speculating
Two anxieties eat at us. One buys someone else's calendar: videos and sermons that turn every war into the last page and leave the believer staring at the sky. The other does the opposite: nothing is going to end, so faith, service, forgiveness at home and study can wait until life settles down.
Mark pounds the table in both directions. Nobody has the date; everyone has their work. That lands this week in normal-sized things: the exam you need to study for, the shift you need to show up early for, the younger sibling to look after, the small group to keep going, the debt to sort out, the conversation to have.
Keeping watch looks very little like a feeling. It looks like praying at a set time and doing well what is in front of you. The command was put to the test quickly: hours later, in Gethsemane, the very one who had said keep awake found them sleeping and asked Peter why he couldn't stay awake one hour (Mark 14:37).
Keeping watch, then, is not scanning the horizon with your phone in your hand. It's working inside, with the lamp lit, until the owner walks through the door and finds us busy.
Think about your real week. What concrete task is in front of you that you keep putting off while you wait to find out when the Lord returns?
