[Timotheist]

Raptor sums it up well.

The duration of the kingdom being 1000 years is unique to Revelation.

Matthew, et. al., refer several times to rewards and punishment, but NEVER mentions the duration.

I personally believe that the punishment is proportional to the crime (you will not come out of prison until you have paid the last cent). So not all will be out for the entire 1000 years.

But do I have "proof" of that belief? no
