God will remains a mystery because we are in a kind of test.
In this time we need free will. Free will needs total privacy. That's why nobody can read our thoughts.
Now in heaven nobody has free will because they saw God directly. At the time you see God there's a transformation and you can't be a human anymore.
There's no free will if you can see God. Like if you have to choose between a marble palace or a piece of chalk.
Jews say that the existence of God in this universe it's like the subtle flavor of wine left in a glass. That's enough for the game of life.
God can be reached through philosophy or/and intuition.
God is not a scientific experiment.
Search your intuition and you will know.
Try to develop your intuition doing some art.
Do you have an objective basis for any of this, or are pulling all of this out of your own... head?
Especially the part about what happens in heaven. Have you been there? Have you spoken to somebody from heaven? Have you read about from a reliable source? What makes your views on heaven any more insightful than a random person on the street?
The problem with basing something on pure intuition is that it can not be verified or examined outside your own head. It cannot possibly be objective, therefore it cannot be rational.
I can also make a logical argument about the following part of your statement.
Now in heaven nobody has free will because they saw God directly. At the time you see God there's a transformation and you can't be a human anymore.
There's no free will if you can see God. Like if you have to choose between a marble palace or a piece of chalk.
This makes no sense at all, even in your own illustration. There may be a reason to choose chalk over marble, for example, if you desire a writing tool, chalk would be the superior choice.
Additionally, why would you ever want to worship a being that will strip you of your free will?
