Be ready for Jesus to return
35 Jesus said, ‘Always be ready for my 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.”
12:35In those days, everybody wore long clothes. To be ready to work, they pulled up the lowest part of their skirt. They then fixed it to their belt, so that they could move easily.
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.’
12:40A robber takes things from someone, when that person is not watching. Jesus is telling those that obey him to be ready for his return. Nobody knows when that will be.
