Luke 12:36-38

36 as though you were waiting for your master to return from the wedding feast. Then you will be ready to open the door and let him in the moment he arrives and knocks.

37 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!

38 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.
