2 Peter 3:9-14

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], [while you earnestly] look for and await the coming of the day of God. For on this day the heavens will be destroyed by burning, and the [material] elements will melt with intense heat! [Is 34:4] But in accordance with His promise we expectantly await new heavens and a new earth, in which righteousness dwells. [Is 65:17; 66:22] So, beloved, since you are looking forward to these things, be diligent and make every effort to be found by Him [at His return] spotless and blameless, in peace [that is, inwardly calm with a sense of spiritual well-being and confidence, having lived a life of obedience to Him].
