Matthew 25:10-13

But while they were going away to buy oil, the bridegroom came, and those who were ready went in with him to the wedding feast; and the door was shut and locked. Later the others also came, and said, ‘Lord, Lord, open [the door] for us.’ But He replied, ‘I assure you and most solemnly say to you, I do not know you [we have no relationship].’ 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].
