Do you take this scripture literally and believe that human beings will be burnt in a fire while Jesus and his angels watch?
What it says is that they will be tormented in the presence of the holy angels and of the Lamb. Something can happen in my presence without me having to watch it all the time.
The angels and the Redeemer will be spending much more of eternity enjoying the sons of God, the New Jerusalem. The full strength of God's undiluted anger upon these ultimate enemies of God, is said to be going on "outside."
" Blessed are those who wash their robes that they may have right to the tree of life and may enter by the gates into the city.
Outside are the dogs and the sorcerers and the fornicators and the murderers and the idolaters and everyone who loves and makes a lie." (Rev. 22:14,15)
This is like having a garbage pale outside of your home. It doesn't necessitate that you stand there all the time enjoying gazing into it.
Can you imagine a wife telling her husband - "Dear, could you go out and watch the garbage" ?
-Removed-I've been down this road with sonship before ~ it's "perfect justice" because er... sonship says so ~ and we are to take it or leave it. Apparently the eternally-burning humans will also be hung out on chains as a warning to those from other worlds. sonship will provide you with the biblical reference for this, presumably.
