Thematic Bible: (unexpectedness of,) of suddenness of Christ's coming

But concerning that day and hour, no one knows, not even the angels of Heaven, neither the Son, but the Father only. For as the days of Noe were, so shall be the coming of the Son of Man. For, as in the days before the flood, they were eating and drinking, marrying and giving in marriage, until the day on which Noe entered into the ark, read more.
and they knew not until the flood came, and took them all away; so will be the coming of the Son of Man.

"And, as it happened in the days of Noah, so will it be also in the days of the Son of Man: they were eating, they were drinking, they were marrying, they were given in marriage, until the day on which Noah entered into the ark, and the flood came, and destroyed them all. Likewise, also, as it happened in the days of Lot; they were eating, they were drinking, they were buying, they were selling, they were planting, they were building; read more.
but on the day on which Lot went out from Sodom, it rained fire and brimstone from heaven, and destroyed them all: after the same manner shall it be in the day the Son of Man is revealed.
