Mark 13:32-37: in context

Jesus is speaking about his return, and he begins by admitting a limit: no one knows the day or the hour, not the angels, not even the Son in his earthly ministry, only the Father. And from that uncertainty he draws a single, repeated command: watch, stay awake, be alert, for you do not know when the time is. He tells a small parable to press it home. A man goes away on a journey, leaving his servants in charge, each with his own work to do, and tells the doorkeeper to keep watch, because no one knows when the master will return, evening, midnight, cockcrow, or morning. And the whole point lands on one word he repeats to everyone: watch, lest he come suddenly and find you asleep.

The danger Jesus names is not open rebellion but sleep. Spiritual sleep is a quieter failure than defiance; it is the slow drift into drowsiness, the living as though the master will never actually return, as though there will be no accounting, no sudden arrival, and so the guard relaxes, the work slackens, the watchfulness fades, and I doze at my post. The master's return being uncertain in timing was meant to keep the servants alert at every hour, ready whenever he came. Instead, uncertainty easily lulls me into treating his coming as so indefinite that it might as well be never, and I fall asleep.

That searches whether I am awake or drowsing. It is easy to slide into a spiritual sleep in which the reality of Christ's return, and of giving an account for the work he left me, becomes a distant abstraction I no longer live in light of, and I drift through my days as though the master were never coming back. Jesus says: stay awake, be found at your post, doing the work he gave you, ready at whatever hour he comes. If the master returned suddenly, tonight, would he find me awake and at my work, or asleep, living as though he were never going to come?
