Luke 12:35-40

(You also must be prepared)

Jesus said to his disciples:
"Gird your loins and light your lamps
     and be like servants who await their master's return from a wedding,
     ready to open immediately when he comes and knocks.
Blessed are those servants
     whom the master finds vigilant on his arrival.
Amen, I say to you, he will gird himself,
     have them recline at table, and proceed to wait on them.
And should he come in the second or third watch
     and find them prepared in this way,
     blessed are those servants.
Be sure of this:
     if the master of the house had known the hour
     when the thief was coming,
     he would not have let his house be broken into.
You also must be prepared, for at an hour you do not expect,
     the Son of Man will come."
