Stay awake for you do not know when your Lord will come.

"Jesus told his disciples this parable:
“The kingdom of heaven will be like ten Virgins who took their lamps and went out to meet the bridegroom.  Five of them were foolish and five were wise. 
The foolish ones, when taking their lamps, brought no oil with them, but the wise brought flasks of oil with their lamps."  (Matthew 25:  1 - 4).

The foolish virgins did not anticipate a delay and were unprepared when the bridegroom was long delayed. (v5)

St. Augustine in his Sermons, 93 wrote: "Watch with the heart, watch with faith, watch with love, watch with charity, watch with good works […]; make ready the lamps, make sure they do not go out […], renew them with inner oil of an upright conscience; then shall the Bridegroom enfold you in the embrace of his love and bring you into his banquet room, where your lamp can never be extinguished."

"Stay awake and be ready!
For you do not know on what day your Lord will come."  (Matthew 24: 42, 44).
