Luke 12:35-40
Jesus warns his disciples to be ready for him to return
35 Jesus said, ‘Always be ready for me to return. Be like people that are ready to start work at any time. They have put on their clothes so that they are ready for work. And they have lit their lamps. 36 You must be like servants that are waiting for their master to arrive. When he returns home from the marriage party, he will knock on the door. His servants should be ready to open it for him immediately. 37 Those servants will be very happy if their master finds them awake. I tell you this. The master will dress himself to give them food. He will say to them, “Sit at the table. I will come to serve you.”
38 The master may arrive in the middle of the night. He may even arrive just before the sun rises. But, if the master finds them awake and ready, the servants will be happy.
39 You can be sure about this. The master of a house does not know when a man might come to rob him. If he knew the time, he would keep awake. He would not let the robber come into his house and take away his things.
40 You also must be ready. The Son of Man will come at a time when you are not thinking about it.’
