and if He did not spare the ancient world of Noah's day, when He brought a flood on those ungodly people (though Noah, a preacher of righteousness, and seven other people, were saved from it);

By [having] faith, when Noah was warned [by God] about conditions that had not yet been seen [i.e., regarding events of the coming Flood], he acted out of reverent concern [for God] by constructing a ship to save [i.e., rescue] his household [from the Flood waters]. By this [i.e., his faith which led to action], Noah condemned the world and inherited righteousness because of his faith.

These people had disobeyed [Noah's preaching, See II Pet. 2:5] back when God's patience waited [for them to repent, See Gen. 6:3], during the days of Noah, when the ship was being constructed. It was by that means [i.e., the ship floating them to safety through the Flood waters] that a few persons, eight of them, were saved [from destruction] through water.

As it was during the days of Noah, so it will be when the presence of the Son of man [arrives]. For in those days before the Flood, people were eating and drinking [i.e., partaking of ordinary meals], men were getting married and women were being given away in marriage [right up] until the day Noah entered the ship. And the people [i.e., of Noah's day] did not know [when it would happen] until the Flood came and swept them all away. It will be the same way when the presence of the Son of man [arrives].
