In Context

5 for this is unobserved by them willingly, that the heavens were of old, and the earth out of water and through water standing together by the word of God,

6 through which the then world, by water having been deluged, was destroyed;

7 and the present heavens and the earth, by the same word are treasured, for fire being kept to a day of judgment and destruction of the impious men.

8 And this one thing let not be unobserved by you, beloved, that one day with the Lord is as a thousand years, and a thousand years as one day;

9 the Lord is not slow in regard to the promise, as certain count slowness, but is long-suffering to us, not counselling any to be lost but all to pass on to reformation,

10 and it will come — the day of the Lord — as a thief in the night, in which the heavens with a rushing noise will pass away, and the elements with burning heat be dissolved, and earth and the works in it shall be burnt up.
