Matthew 24:37-44

For the coming of the Son of Man (the Messiah) will be just like the days of Noah. For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the [very] day when Noah entered the ark, and they did not know or understand until the flood came and swept them all away; so will the coming of the Son of Man be [unexpected judgment]. [Gen 6:5-8; 7:6-24] At that time two men will be in the field; one will be taken [for judgment] and one will be left. Two women will be grinding at the mill; one will be taken [for judgment] and one will be left. “So be alert [give strict attention, be cautious and active in faith], for you do not know which day [whether near or far] your Lord is coming. But understand this: If the head of the house had known what time of the night the thief was coming, he would have been on the alert and would not have allowed his house to be broken into. [Luke 12:39, 40] Therefore, you [who follow Me] must also be ready; because the Son of Man is coming at an hour when you do not expect Him.
