2 Peter 3:8-10

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.
