Matthew 25:1, 6, 13

“Then the kingdom of heaven will be like ten virgins, who took their lamps and went to meet the bridegroom.

But at midnight there was a shout, ‘Look! The bridegroom [is coming]! Go out to meet him.’

Therefore, be on the alert [be prepared and ready], for you do not know the day nor the hour [when the Son of Man will come].
