The following discourse by the apostle Peter frames well what will happen next:
1 I stir up your pure minds by way of remembrance:
2 That ye may be MINDFUL1 of the words which were spoken before by the holy prophets, and of the commandment of us the apostles of the Lord and Saviour:
3 Knowing this first, that there shall come in the LAST DAYS SCOFFERS, walking after their own lusts,
4 And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation.
5 For this they willingly are IGNORANT of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water:
6 Whereby the world that then was, being OVERFLOWED WITH WATER, PERISHED:
7 But the heavens and the earth, which are now, by the same word are kept in store, RESERVED UNTO FIRE against the DAY OF JUDGMENT and perdition of ungodly men.
8 But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
9 The LORD IS NOT SLACK concerning his promise, as some men count slackness; but is LONGSUFFERING to us-ward, not willing that any should perish, but that all should come to REPENTANCE.
10 But the day of the Lord will come as a thief in the night; (2 Peter 3)
1) Mindful – It’s quite simple. There is a holy book of scripture called The Bible. It is a historical record, without which, much of what we know about history would be lost. Secondly, it shares otherworldly information which may or may not be known by all, which includes angels (good and evil) and information about the creator (God).
It offers laws (10 Commandments) that have become the basis for many legal systems. It provides examples of human nature and frames the world in a context that explains it—inclusive of the creator. It teaches and warns about an afterlife and a time of judgment for each person and the world as a whole.
It contains prophecies (promising good and warning of bad) that were given and fulfilled a mention of not just doubters, but those who laughed, ignored, and scoffed. In other words, on top of all that the Bible is, it is also a Book of Prophecy and has a proven track record of being right. Peter is saying, people should not be ignorant of this fact, and in particular, how God brought a flood—just as His prophet prophesied—which was no small feat, and is reminding doubters of another prophecy that will yet be fulfilled:
7 But the heavens and the earth, which are now, by the same word are kept in store, RESERVED UNTO FIRE against the DAY OF JUDGMENT and perdition of ungodly men. (2 Peter 3)
Other translations put it like this:
7 But by His word the present heavens and earth are being reserved for fire, being kept for the day of judgment and destruction of the ungodly people. (AMP)
7 And by the same word, the present heavens and earth have been stored up for fire. They are being kept for the day of judgment, when ungodly people will be destroyed. (NLT)
Just like the earth experienced a worldwide flood that destroyed the wicked, so too is the earth destined to experience a fire that will destroy the wicked.
