I have wondered about those things too. The Bible give little or no info about it I think.
Especially in Revelation there are some discription of gold, jewels. Worshipping creatures at the the throne of God etc. God just sitting there. I somehow think it's different. But how?
What actually is all in all? Let we start saying I don't know. But I have a quite strong feeling it doesn't mean we all have the same mind.
Father, Son and HS all are without sin. Right? But still they are different.
I look at it like sports fans. Some like baseball. Some football. Both sports. But different sports.
I also see creation as little parts of God. You know we are His breath in the creation account.
So we have a perfect God. Lonely perhaps because I wants children? He creates us. Subjects us to a teaching process. Then finally we are taught and pure and then we become all in al, meaning exactly the same (as God)
Then what was gained for God? A whole process to make something that was exactly as it was before.
Isn't the fun of family that all are a bit different?
So I think it looks more like a football team. All individuals. But all working for the victory the team.
I can tell you what my heaven would be
Those who do try to describe heaven usually have a lot of gold, silver, diamonds and other jewels radiating bright light. I like to sink my god-given feet into the soil (I seldom wear shoes) so I can't imagine a worse place than one made of hard metals with stones scattered about. Give me grass, shade trees and garden soil rich in humus. Fill the air with the scents of flowers, moldering leaves, ocean spray. Lift my spirits with chirping brooks and bird songs.
But.... we are changed in a twinkling of the eye. What we find boring now we may like in heaven.
Right now on earth for some people heaving is doing extreme sports like rafting. And for others it's sitting in the attic looking at their stamp collection. Just wanna say what we like most can change....
