Gospel of Luke 12:35-40
See that you are prepared.
Jesus said to his disciples: ‘See that you are dressed for action and have your lamps lit.
Be like men waiting for their master to return from the wedding feast, ready to open the door as soon as he comes and knocks. Happy those servants whom the master finds awake when he comes. I tell you solemnly, he will put on an apron, sit them down at table and wait on them.
It may be in the second watch he comes, or in the third, but happy those servants if he finds them ready. You may be quite sure of this, that if the householder had known at what hour the burglar would come, he would not have let anyone break through the wall of his house. You too must stand ready, because the Son of Man is coming at an hour you do not expect.’
