I believe that this matter was resolved in the 1st century as many would agree. Because it says in Rev 20.3 the nations are not deceived in the 1000 years. How can we say the nations are not deceived today when 10,000 children die every day due to starvation and we continue to hear of wars and rumors of wars?

We are also told Satan is the god of this world today, so how could he be in the pit now? Satan wasn't put in the pit when Jesus died on the cross. So he continues to operate today. Hence, the need for spiritual warfare.

Satan is put in the pit for 1000 years. But that can't be after eternity future because it says he is released at the end of the millennium. Eternity future goes on forever. So the millennium can't be eternity future in the New City and New Earth, because all things are reconciled before then.

"In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them" (2 Cor 4.4).

"And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season" (Rev 20.3).
