Matthew 24:36-44

36 "But when that day and hour will come, no one knows -- not the angels in heaven, not the Son, only the Father.
37 For the Son of Man's coming will be just as it was in the days of Noach.
38 Back then, before the Flood, people went on eating and drinking, taking wives and becoming wives, right up till the day Noach entered the ark;
39 and they didn't know what was happening until the Flood came and swept them all away. It will be just like that when the Son of Man comes.
40 Then there will be two men in a field -- one will be taken and the other left behind.
41 There will be two women grinding flour at the mill -- one will be taken and the other left behind.
42 So stay alert, because you don't know on what day your Lord will come.
43 But you do know this: had the owner of the house known when the thief was coming, he would have stayed awake and not allowed his house to be broken into.
44 Therefore you too must always be ready, for the Son of Man will come when you are not expecting him.
