Mark 13:32-37

32"But concerning that day or that hour, no one knows, not even the angels in heaven, nor the Son, but only the Father.

33Be on guard, keep awake. For you do not know when the time will come.

34It is like a man going on a journey, when he leaves home and puts his servants in charge, each with his work, and commands the doorkeeper to stay awake.

35Therefore stay awake—for you do not know when the master of the house will come, in the evening, or at midnight, or when the rooster crows, or in the morning—

36lest he come suddenly and find you asleep.

37And what I say to you I say to all: Stay awake."
