~ Matthew 24:32-41
32"Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. 33Even so, when you see all these things, you know that it is near, right at the door. 34I tell you the truth, this generation will certainly not pass away until all these things have happened. 35Heaven and earth will pass away, but my words will never pass away.
36"No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father. 37As it was in the days of Noah, so it will be at the coming of the Son of Man. 38For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; 39and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man. 40Two men will be in the field; one will be taken and the other left. 41Two women will be grinding with a hand mill; one will be taken and the other left.
