2 Peter 3:9

7 And by that same word, the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of ungodly men.

8 Beloved, do not let this one thing escape your notice: With the Lord a day is like a thousand years, and a thousand years are like a day.

The Lord is not slow in keeping His promise as some understand slowness, but is patient with you, not wanting anyone to perish but everyone to come to repentance.

10 But the Day of the Lord will come like a thief. The heavens will disappear with a roar, the elements will be destroyed by fire, and the earth and its works will be laid bare.

11 Since everything will be destroyed in this way, what kind of people ought you to be? You ought to conduct yourselves in holiness and godliness

Do read the surrounding verses too, because the context often says more than a single verse.
