2 Peter 3:8-13

Nevertheless, do not let this one fact escape you, beloved, that with the Lord one day is as a thousand years and a thousand years as one day. [Ps. 90:4.] The Lord does not delay and is not tardy or slow about what He promises, according to some people's conception of slowness, but He is long-suffering (extraordinarily patient) toward you, not desiring that any should perish, but that all should turn to repentance. But the day of the Lord will come like a thief, and then the heavens will vanish (pass away) with a thunderous crash, and the [material] elements [of the universe] will be dissolved with fire, and the earth and the works that are upon it will be burned up. Since all these things are thus in the process of being dissolved, what kind of person ought [each of] you to be [in the meanwhile] in consecrated and holy behavior and devout and godly qualities, While you wait and earnestly long for (expect and hasten) the coming of the day of God by reason of which the flaming heavens will be dissolved, and the [material] elements [of the universe] will flare and melt with fire? [Isa. 34:4.] But we look for new heavens and a new earth according to His promise, in which righteousness (uprightness, freedom from sin, and right standing with God) is to abide. [Isa. 65:17; 66:22.]
