Watch therefore: for you know not what hour your Lord does come.
All Commentaries on Matthew 24:42 Go To Matthew 24
John Chrysostom
AD 407
But his meaning is like this: If ordinary persons knew when they were going to die, they would surely be striving earnestly at that hour. In order therefore that they may strive, not at that hour only, he does not tell them the hour or day. He wants to keep them on their toes looking for it, that they may be always striving. This is why he made the end of each person’s life so uncertain. In this passage he openly implies that he himself is Lord. Nowhere before has he spoken of this so distinctly. But here he seems to me also to be putting to shame those who remain careless about his lordship. They take much more care about a thief taking their money than about their own soul. Those who care about their house and do not want their possessions stolen take measures against the thief. They watch; they are prepared for the thief. So it is with you. You do not know when he will come. But you know assuredly that he will come. If you do not continue to watch, you will not be ready on that day. You will be unprepared. Destruction will come in your sleep. If the person had known when the thief was coming, he would have been prepared. So be like the one who is prepared at all times, so you will escape free.Having then mentioned the judgment, he directs his thoughts next to teachers, speaking of honorable and dishonorable actions. His discourse closes with that which is alarming, for he speaks first of those who do right, then of those who continue in sin. The Gospel of Matthew, Homily
