1 Peter 4:7

But the end of everything [as far as your lives are concerned] is near, so be sensible, and sober [so as to be] prayerful.

Hebrews 11:7

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.

2 Peter 3:6-7

[And] it was by water that the world, which existed at that time, perished in a great flood [of Noah's day]!

2 Peter 3:10-12

But the day of the Lord will come as a thief [i.e., unexpectedly]. At that time the heavens will pass away with a loud noise and the elements [Note: This refers either to the heavenly bodies or to the material components of the universe], will be dissolved with intense heat. And the earth and its works [i.e., its activities] will be burned up. [Note: Some translations render this phrase as it is in some ancient manuscripts, "will be disclosed," or "will be laid bare"].
