Then how do you explain the hiddenness of god?
Liberty.
We are in a time of test. Our lifetimes here on earth will show if we freely want to live with God or not.
This choice can only be made while we are alive. After death your intentions throughout your life will be fixed in your soul forever with no turning back.
Why no turning back? The free will our souls possess will be over in Heaven? No second chances after death?
Yes.
Why?
Because if you are confronted with two extreme unequal choices you lose your ability to freely choose. After death you will be able to see God and his reality in all his Glory. That would be the equivalent of a choice between receiving for free a marble and gold palace or a piece of chalk.
You can't use your freedom of choice in a situation like that. So God indeed intentionally hides His total Glory (reveals indirectly only a very little fraction of it) from us in this period in our lives.
That's why we say a man cannot see the Glory of God without dying. A man without its total freedom of choice is not a man anymore.
Freedom of choice needs total privacy too, that's why your mental intentions cannot be read by anyone. You have total privacy about your deepest thoughts/intentions.
You can change your intention as you wish while alive, you even can change it in your last breath. After that your will/intention will be fixed forever in your soul.
