The spiritual mindset is the mindset which is in agreement with the Word of God. Your statement that "this physical world and the elements of it is (not) what God desires" seems to me to be based on a misunderstanding of certain things.
The "elements of the world" are to be "burned up" in judgment, thus the world that is, is to be destroyed by fire. Just as the previous world was destroyed by water. Yet, when the previous world was destroyed by water, it wasn't a total annihilation of physical reality, it was a destruction of the then existing world order, society, humans and their animals.
John 18:36
Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence.
He was talking about the temple, city of Jerusalem Etc. He told pilate if my kingdom was of the world my people would fight for this city, yet he said my kingdom is not of this world. Paul told the Romans “it is not meat and drink but righteousness, peace, and joy in the Holy Ghost.”
This world is part of Gods plan, he is not going to burn it up.
Genesis 8:22
While the earth remaineth, seedtime and harvest, and cold and heat, and summer and winter, and day and night shall not cease.
The only thing that burnt up as to what your talking about is....
Revelation 19:20
And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
Jerusalem, the temple, city, and all the inhabitants were destroyed.
In conclusion this earth will remain, souls will be saved, miracles performed, and Gods spirit at liberty.
I’m answering some of the ones I can before I have to leave.
