2 Peter 3:8

4 “Where is the promise of His coming?” they will ask. “Ever since our fathers fell asleep, everything continues as it has from the beginning of creation.”

5 But they deliberately overlook the fact that long ago by God’s word the heavens existed and the earth was formed out of water and by water,

6 through which the world of that time perished in the flood.

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.

9 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

12 as you anticipate and hasten the coming of the day of God, when the heavens will be destroyed by fire and the elements will melt in the heat.
