How will everyone be judged if there is so many people?

Could be all at the same time. God is everywhere at once so He could reveal our sins to us in our minds all at once. Who knows! lol Ask that one guy who came back from Heaven and wrote a book about it!

Remember that there will be no earthly "time" in Heaven. We won't be sitting there counting the minutes or hours or days of the Judgement, however short or long it may be

I tend more toward the idea that we will each have a one-on-one moment with Him, not that it's going to be a big group "mind meld" sort of thing. From what I've read of near-death experiences and such, people often mention being taken on a "tour" of their lives, from birth to death, and seeing every single moment, yet it seems to only take a very short time. I imagine "time" moves a lot differently in the spirit world.

The judging will be from the Lamb's Book of Life - if your name is not entered, Jesus said I know them not - depart from me. The Judgement for Christians will be your works will be put through the fire - what you did for selfish reasons will burn up and what is left will be your rewards. It will not be like a trial - it will be fast and direct.

It will be one-on-one with Jesus. However, Jesus is perfectly capable of talking to me about my life, my sins and my rewards at the same time as He's talking to you about yours, and my husband about his, and my neighbor. . . . etc.
