If you were to die this very moment and met Jesus face to face -
What is the first thing He would say to you.
I think the first thing we'll hear at the judgement seat will be our name.
Any attempt to extrapoloate anything after that would be sheer conjecture, although I think we'll have some idea of our fate by the expression on God's face even before there is any "spoken" exchange.
One thing that intrigues me (along with a lot of other things) is that everybody who has just died will have their own personal perception of the judgement seat.
At the moment there are about 8 billion people in the world and on average 107 people die per minute around the world.
If the judgement takes five minutes in our time (just surmising) then 535 people would similtaneously have a vision of the judgement seat as though it was reserved exclusively for them.
God does a lot of multitasking.
The reason I say "Five minutes" is that I've long claimed that the night my father died he appeared in my room. From the expression on his face he was either looking at something behind and above me that filled him with awe. At other times he ws trying to hid his face behind his hands as though he could not stand what he was watching (at those time I think he was seeing less salubrious aspects of his life being played back).
Now we had a full blown conversation. I don't know how long it took but five minutes was probably long enough. He'd just died, we had an exchange, and then judgement was pronounced all in a few minutes. It didn't take long.
As an afterthought something was coming for him from my left which caused him to give a terrifying scream just before he disappeared into eternity. Since I was sitting up in bed at the time and facing him, then I assume the "judge" was also facing the same way as I was.
In anthropromorphic terms, if the business about the sheep on the right and the goats to the left has any literal significance, he went to the left.
Just a speculative afterthought.
I think it's pretty quick. But at the same time several hundred other people were probably having a similar experience as though the judgement was theirs and theirs alone.
Between monitoring our thoughts, words, actions and those actions we should have done as 8 billion people hurtle through the universe at about 300 or so kilometres per second, maintaining the universe, watching over heaven, hell and purgatory, listening to prayers, watching angels and demons, and looking into the past, present and future, God keeps Himself busy.
As Christ said, "My Father is always working...."
