But know this, that if the owner of the house had known in what watch the thief would come, he would have watched, and would not have allowed his house to be broken into.
All Commentaries on Matthew 24:43 Go To Matthew 24
Hilary of Poitiers
AD 368
To teach us that our ignorance of the date of his return (which his silence has kept hidden from everyone) is not without its usefulness, Christ warns us to keep all his commandments. We should also be occupied with constant prayer in order to guard against the coming of the thief. For the thief is the devil who seeks to invade our bodily homes with the darts of his thoughts and allurements in order to ruin us while we are sleepy and careless. It is good therefore that we be prepared. Our ignorance of the day of Christ’s return should provoke us to be careful as we eagerly await his coming.
