For as it was in the days of Noah, so it will be at the coming of the Son of Man. In (those) days before the flood, they were eating and drinking, marrying and giving in marriage, up to the day that Noah entered the ark. They did not know until the flood came and carried them all away. So will it be (also) at the coming of the Son of Man. Two men will be out in the field; one will be taken, and one will be left. Two women will be grinding at the mill; one will be taken, and one will be left. Therefore, stay awake! For you do not know on which day your Lord will come. Be sure of this: if the master of the house had known the hour of night when the thief was coming, he would have stayed awake and not let his house be broken into. So too, you also must be prepared, for at an hour you do not expect, the Son of Man will come. (Mt 24:37-44)
The coming of the Son of Man (the second coming) is not known. People and the followers are waiting for the second coming. Nobody knows when exactly this will be. The believers should be ready always for this event. The early Church believed that Jesus will return to the earth and take the central place on that day.(Acts 1:1; Col 3:4; Jn 3:2)
But life will go on as normal right up to the last minute (as in the days of Noah). People will continue their normal human, social life. They live the present (which they should) without any expectation or awaiting or being ready for the future. Christian life is also based on hope.
This event will divide families and working companions. Each one has to face the event independently and individually. So the disciples should stay awake and wait and one should be ready to receive the Son of Man. Keeping awake and being ready are the ways in which one can face the day of the Lord.
