But you said the 1,000 years symbolically represents the Lord's ETERNAL realm.
But you contradict yourself, implying that the Lord's ETERNAL realm has a beginning - which according to you, was in the 1st century - and an end - which according to you, is when Satan will be released from prison, - and then the Lord's eternal realm (symbolized by 1,000 years, according to you) will be followed by - what - by another eternal realm?
I agree. The New Heavens and New Earth + the 1,000 years are metaphors for the Lord's ETERNAL realm
- which the New Testament calls the ages of the ages -
and Satan will be bound for the first 1,000 years of it
- but just as he was allowed to deceive Adam and Eve in paradise the first time, so he will be given one final opportunity after being released at the close of that first 1,000 years to deceive the nations again - just as Revelation 20 tells us - before you go and change it, corrupting what scripture says.
