“As it was in the days of Noah, so shall it be with the coming of the Son of man. In the days before the flood, they were eating and drinking, marrying and being given in marriage, even to that very day in which Noah entered into the ark. They did not suspect what was happening until the flood came and swept them all away. So shall the coming of the Son of man also be… Watch therefore, because you do not know at what hour your Lord will come.”
Matthew 24: 37-42
