You mention the final judgment of the earth by fire and that everything is going to be burned up. I hope you will consider the following observations:
-My Greek Interlinear New Testament says, of 2Peter 3:10, 'the elements will be dissolved by burning and the earth and the works in it will be discovered.'
Jonathan Mitchell's translation of the NT is quite literal and is rather ponderous because it tries to give several possible renderings. It says, 'So the day of the Lord (=Yahweh) will arrive as a thief (i.e., suddenly and without notice), in which (day) the heavens (or atmospheres, skies) will pass by with noise of sudden movement, but so rudimentary, elementary principles (or basic components and parts of a system arranged in rows, or a grid; e.g., the elements and assumptions of a religious or intellectual system) being progressively heated as with a burning fever, will be loosed (unfastened, unbound or nullified, destroyed). And then land (or soil, ground, earth, or a territory) - along with the things produced (or actions, deeds, workmanships, accomplishments, note: God's or man's) within the midst of it will be found (or discovered, found out).
The Greek word translated here as elements or elementary principles is stoicheion. Strong's Concordance (#4747) says it means constituent, proposition, element, principle or rudiment.
This word is also found elsewhere in the NT:
Col 2:8, 'See to it that no one takes you captive through philosophy and empty deception, according to the elementary principles (stoicheia) of the world rather than according to Christ.
Col 2:20, 'If you have died with Christ to the elementary principles (stoicheion) of the world...'
Gal 4:9, 'But now that you have come to know God, or rather to be known by God, how is it that you turn back again to the weak and worthless elemental things (stoicheia), to which you desire to be enslaved all over again.'
-the article quotes Luke 17:26-29 which talk about Noah's flood and Sodom & Gomorrah. In vs 27 & 29 the Greek word apolesen is translated 'destroyed'. It is derived from the word apollumi (Strong's #622) meaning to destroy fully, perish, lose, die or mar. Vine's Expository Dictionary says, 'the idea is not extinction but ruin, loss, not of being, but of well-being'. It can be literal or figurative. It has quite a range of meaning and was used to describe the lost coin, lost sheep and the prodigal son of Luke 15, and as you know, they were all eventually recovered.
-in Genesis 8:21, immediately after the flood, God says, 'and I will never again destroy every living thing, as I have done.' In chapter 9 God makes a covenant not only with Noah but his descendants and 'every living creature that is with you, the birds, the cattle and every beast of the earth with you;' saying 'all flesh shall never again be cut off by the water of the flood'. He repeats this promise and explains the symbolism of the rainbow. So, was He qualifying the promise to all creatures He gave in chapter 8 about not destroying them by only ruling out the second use of water as his agent of destruction? I would think that being burned to death would be more painful for creatures than being drowned. Yes, the flood could be a type of the judgment fire but water is also a symbol of the Holy Spirit. Habakkuk 2:14 says, 'For the earth will be filled with the knowledge of the glory of the Lord, as the waters cover the sea.'
-Jesus came to end the curse put on the ground in Gen 3:17 (all of the dominion given to Adam) caused by Adam's sin. Romans 8:19-23 says all creation groans, awaiting in hope the time it will be set free from 'its slavery to corruption' when believers will finally be adopted as sons, the time of 'redemption of our body'. Part of this original creation made it through the flood (Noah's family, the animals he took, and the dove he released returned with an olive branch) and subsequently respread throughout the earth. So, is this creation, which has been struggling under the curse for so long not to be finally set free, but rather consumed by fire?
-in Luke 9:54-56, when the disciples asked Jesus to 'command fire to come down' and consume the people of a village that did not receive Jesus, He rebuked them by saying, in effect, such a thing was not of God. Yet, in Luke 12:35-53, in imploring His disciples to be ready for the return of their master, He says, 'I have come to cast fire upon the earth; and how I wish it were already kindled.' He goes on to explain His statement in terms of His coming trials and execution and the friction that division about Him will cause, even between members of a family. He was not talking about literal fire.
