Luke 17:24-27

24For just like the lightning, when it flashes out of one part of the sky, gives light to the other part of the sky, so [visible] will the Son of Man be in His day.

25But first He must suffer many things and be repudiated and rejected and considered unfit [to be the Messiah] by this [unbelieving] generation.

26And just as it was in the days of Noah, so it will be in the time of [the second coming of] the Son of Man:

27the people were eating, they were drinking, they were marrying, they were being given in marriage, [they were indifferent to God] until the day that Noah went into the ark, and the flood came and destroyed them all.
