The Last Judgement: a civilized trial or a barbaric ordeal? From the Book of Revelation I've got the idea that the Satan will be our prosecutor at the Last Judgement. I've got this idea by interpreting the word 'accuser' as 'prosecutor' in the context of the Book of Revelation. 

So I can imagine the Last Judgement as a very civilized trial with a prosecutor and, perhaps, other things similar to what we have here on Earth in civilized countries. 

But then the Book also says that at the Last Judgement "the deeds of everyone will be exposed". It can be thought then that no formal procedure is required at the Last Judgement and there will be no prosecutor nor anything.

So, then is it correct to understand that at the Last Judgement the Satan will be our prosecutor? Otherwise how I will even know what I am accused of??
Neither. You're asking the wrong question.

Earthly and fallable court systems work one way. As omniscient maker of the universe and its sovereign King, God is not required to work quite the same way. We use the imagery of a courtroom to talk about the last judgement, but it is just imagery. The actual proceedings are a little different.

For one thing, there won't be a "discovery" phase. God knows every detail of your life backwards and forwards better than you do -- including your motivations. There will be nothing to argue, nothing to learn.

You will be found guilty.

What role Satan may play is not terribly important. He is an accuser and would love to remind God of the fact that you are guilty. But God already knows that. You are going to know it too. There won't be any doubt.

The only question remaining is, who is your defense. You will either have none at all, or if you belong to Him, you will have Christ who can step up and say, "That one is mine, I paid his ransom, I have removed his guilt and made him a new creation."

The guilty will have no chance of slipping through because some evidence against them is inadmissible. There is no jury that might let things slide. There will be no question about the strength of the evidence, whether presented by Satan or whether it's just known.

There is nothing barbaric in this. You will either be administered perfect justice or you will be redeemed through another having been justly punished in your place.
