LOL. So, Peter commented on it for no reason? You think he was telling him to look at what the prophets had written and proceeded to talk about it himself while fully expecting them to ignore what he said and only look at what the OT prophets said?
No. Have you ever entered a conversation in the middle and were unaware of what people were talking about? I did. Last week. I showed up late to a zoom meeting already in progress. And I was lost almost the whole time. I could understand the words okay. But I was missing vital information (what was said before) essential to my understanding.
Efficiency is an aspect of human communication. Those who came to the meeting on time, were not going to back track to the beginning of the conversation to fill me in. But if they did fill me in, then I would have understood better.
The same is true of Peter's readers. He alerts them to the fact that they need to know what was already said previously in order to understand what he is about to say. He mentions three things in particular: (1) the creation of the world, (2) destruction of the world by water, and (3) destruction of the world by fire. His argument depends on familiarity with all three of these subjects.
Peter is being brief, and concise. What he says in two verses here is not the sum and substance of everything the Bible reveals about the destruction of the earth by fire.
The problem with your view is that you don't understand why it is said to come as a thief in the night. What that means is that it will come suddenly and unexpectedly.
What did I say that lead you to believe this about my point of view? Of course the day comes suddenly and unexpectedly. It doesn't follow, therefore, that the day isn't longer than a 24hour period.
1 Thessalonians 5:1 Now, brothers and sisters, about times and dates we do not need to write to you, 2 for you know very well that the day of the Lord will come like a thief in the night. 3 While people are saying, “Peace and safety,” destruction will come on them suddenly, as labor pains on a pregnant woman, and they will not escape.
What passages like this one and 2 Peter 3:10-12 indicate is that it is the destruction accompanying the arrival of the day of the Lord that will come as a thief in the night. Paul indicated that the "destruction will come on them suddenly". And, significantly, he pointed out that "they will not escape". If you see 2 Peter 3:10-12 as describing the literal burning up of the earth then it becomes clear why Paul said that "they will not escape".
I'm not saying that you can't read it that way. Your interpretation is certainly plausible. But not necessarily so.
Why didn't Peter said we are looking forward to an earthly kingdom instead of the NHNE then?
Because the earthly kingdom isn't permanent.
What nonsense. There is no basis whatsoever for thinking that Paul taught about some other day of the Lord than Peter taught about. That is just plain ludicrous.
Did I say there was more than one day of the Lord? I don't think I did. I maintain that the Day of the Lord is at least a thousand years long. And the inauguration of the Day of the Lord is the locus and the fire armies spoke of by Joel the prophet. That is what Paul is talking about. Peter is talking about the big whoosh, which comes at the end of the Millennial period.
