Mark 13:32-37

Nobody knows when the Son of Man will return to the world

32 Nobody knows the day or the hour when all these things will happen. Only God the Father knows when they will happen. The angels who are in heaven do not know. Even the Son does not know. 33 Watch carefully! Keep awake! You do not know the time when all these things will happen. 34 It is like when a man begins a journey. Before the master leaves his house, he gives authority to his servants. He tells each servant about the work that he should do. Then he tells the servant at the door to watch for his master's return.

35 So, you must watch carefully. You do not know when the master of the house will come back. He might arrive in the evening, or in the middle of the night. Or he might arrive early in the morning, or just before the sun rises. 36 When he arrives, he may surprise you. He may even find you asleep! 37 I am saying this to you. I am also saying this to everyone else. Always be ready!’
