The rapture/our glorification, occurs at his coming, so start reading from there.
Peter looks for a NHNE in his glorified state as he waits for his coming.
10 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.
11 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], 12 [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! 13 But in accordance with His promise we expectantly await new heavens and a new earth, in which righteousness dwells.
3 First of all, know [without any doubt] that mockers will come in the last days with their mocking, following after their own human desires 4 and saying, “Where is the promise of His coming [what has become of it]? For ever since the fathers fell asleep [in death], all things have continued [exactly] as they did from the beginning of creation.”
5 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, 6 through which the world at that time was destroyed by being flooded with water. 7 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.
