I see. Fair enough.
For me personally, I interpret the following verse as showing Body, Soul and Spirit as a Trinity and as separate distinct entities...
1 Thessalonians 5:23
"And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ"
I'm a big Trinity fan... so sue me lol.
I would like to offer my view on the word 'destroyed', based on not only Scripture but the world around us.
Whenever something is 'destroyed' it's never 100%. There is always something left over.
For example: When a building is destroyed, it doesn't magically disappear. There is rubble left over.
When an object is burned, generally speaking, ashes are left behind.
In Science, Energy is not destroyed but transferred...
"This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another"
Conservation of energy - Wikipedia
Thus, the point I'm making is that whatever gets thrown into the Lake of Fire has a 'remnant' piece leftover that God now has to do something with.
I believe that remnant piece is the Spirit.
It's what God does with the leftovers that, in my humble opinion, is the Elephant in the Room no one wants to talk about.
I say it gets transferred. In other words, it gets re-purposed...
Ecclesiastes 1:9
"The thing that hath been, it is that which shall be; and that which is done is that which shall be done: and there is no new thing under the sun"
We are in an endless cycle. A loop of time if you will. If One takes the above verse literally (as I do), then that means we were here before. We didn't 'cut the mustard'. We were re-purposed... just as Jesus teaches.
The only thing different this time around is that we found the escape route.
Scripture calls this re-purposing 'Mystery of Iniquity'.
Jesus is the way out. Amen.
