See the notes at Matthew 24:37-39.

As it was in the days of Noe - See on Matthew 24:38 (note).

And as it was in the days of Noe,.... Whilst he was building the ark, and before he went into it; for this respects the days of Noah before the flood, and not after it; for he lived after the flood three hundred and fifty years, Genesis 9:28

so shall it be also in the days of the son of man; some time before, and at his coming in power, and great glory, to destroy the Jews, their nation, city, and temple; and as then, so it will be when he shall come in person, at the last day, to destroy the world: the times of Noah's flood, of Jerusalem's destruction, and of the end of the world, bear a great resemblance to each other: and when the son of man comes in either of these senses, then will the kingdom of God come; or then will it appear that the Messiah is come, and has took to himself his great power, and reigns.

{10} And as it was in the days of Noe, so shall it be also in the days of the Son of man.

(10) The world will be taken by surprise with the sudden judgment of God, and therefore the faithful ought to continually watch.

26-30. eat . married . planted-all the ordinary occupations and enjoyments of life. Though the antediluvian world and the cities of the plain were awfully wicked, it is not their wickedness, but their worldliness, their unbelief and indifference to the future, their unpreparedness, that is here held up as a warning. Note.-These recorded events of Old Testament history-denied or explained away nowadays by not a few-are referred to here as facts.

17:20-37 The kingdom of God was among the Jews, or rather within some of them. It was a spiritual kingdom, set up in the heart by the power of Divine grace. Observe how it had been with sinners formerly, and in what state the judgments of God, which they had been warned of, found them. Here is shown what a dreadful surprise this destruction will be to the secure and sensual. Thus shall it be in the day when the Son of man is revealed. When Christ came to destroy the Jewish nation by the Roman armies, that nation was found in such a state of false security as is here spoken of. In like manner, when Jesus Christ shall come to judge the world, sinners will be found altogether regardless; for in like manner the sinners of every age go on securely in their evil ways, and remember not their latter end. But wherever the wicked are, who are marked for eternal ruin, they shall be found by the judgments of God.
