Luke 12:44 (KJV)

And this know, that if the goodman of the house had known what hour the thief would come, he would have watched, and not have suffered his house to be broken through.

Be ye therefore ready also: for the Son of man cometh at an hour when ye think not.

Then Peter said unto him, Lord, speakest thou this parable unto us, or even to all?

And the Lord said, Who then is that faithful and wise steward, whom his lord shall make ruler over his household, to give them their portion of meat in due season?

Blessed is that servant, whom his lord when he cometh shall find so doing.

But and if that servant say in his heart, My lord delayeth his coming; and shall begin to beat the menservants and maidens, and to eat and drink, and to be drunken;

The lord of that servant will come in a day when he looketh not for him, and at an hour when he is not aware, and will cut him in sunder, and will appoint him his portion with the unbelievers.

And that servant, which knew his lord's will, and prepared not himself, neither did according to his will, shall be beaten with many stripes.

But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more.

I am come to send fire on the earth; and what will I, if it be already kindled?
