Luke 12:37-40

The servants who are ready and waiting for his return will be rewarded. I tell you the truth, he himself will seat them, put on an apron, and serve them as they sit and eat! He may come in the middle of the night or just before dawn. But whenever he comes, he will reward the servants who are ready. “Understand this: If a homeowner knew exactly when a burglar was coming, he would not permit his house to be broken into. You also must be ready all the time, for the Son of Man will come when least expected.”
