Passage
through which [waters] the then world, deluged with water, perished.
through which [waters] the then world, deluged with water, perished.
2 Peter 3:4 and saying, Where is the promise of his coming? for from the time the fathers fell asleep all things remain thus from [the] beginning of [the] creation.
2 Peter 3:5 For this is hidden from them through their own wilfulness, that heavens were of old, and an earth, having its subsistence out of water and in water, by the word of God,
2 Peter 3:6 through which [waters] the then world, deluged with water, perished.
2 Peter 3:7 But the present heavens and the earth by his word are laid up in store, kept for fire unto a day of judgment and destruction of ungodly men.
2 Peter 3:8 But let not this one thing be hidden from you, beloved, that one day with [the] Lord [is] as a thousand years, and a thousand years as one day.
The verse centers on "world", "through", "waters", "deluged", and "perished". It is saying that the verse draws attention to "world" and "through", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "For this is hidden from them through..." into verse 7's "But the present heavens and the earth...", so "world" and "through" belong inside that flow. In 2 Peter context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "world" and "through" with trust shaped by these words, not by a vague optimism outside the passage.
