2 Peter 3:5-11

For they willingly forget [the fact] that the heavens existed long ago by the word of God, and the earth was formed out of water and by water, through which the world at that time was destroyed by being flooded with water. [Gen 1:6-8; 7:11] 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. Nevertheless, do not let this one fact escape your notice, beloved, that with the Lord one day is like a thousand years, and a thousand years is like one day. [Ps 90:4] The Lord does not delay [as though He were unable to act] and is not slow about His promise, as some count slowness, but is [extraordinarily] patient toward you, not wishing for any to perish but for all to come to repentance. But the day of the Lord will come like a thief, and then the heavens will vanish with a [mighty and thunderous] roar, and the [material] elements will be destroyed with intense heat, and the earth and the works that are on it will be burned up. Since all these things are to be destroyed in this way, what kind of people ought you to be [in the meantime] in holy behavior [that is, in a pattern of daily life that sets you apart as a believer] and in godliness [displaying profound reverence toward our awesome God]
