“Be alert; be wakeful. You do not know when the moment comes.
“It is like a man away from home; he has left his house and put his servants in charge, each with his own work to do, and he has ordered the door-keeper to stay awake. Keep awake, then, for you do not know when the master of the house is coming. Evening or midnight, cock-crow or early dawn–if he comes suddenly, he must not find you asleep. And what I say to you, I say to everyone: Keep awake.”
