When you say 'new earth' you are already out if the box, it seems follows your thinking.I believe the earthly land promises to the Jews was literally fulfilled in the days of Joshua, and that the spiritual promises (to both Jews and Gentiles) of a heavenly Kingdom were fulfilled in Jesus Christ.
All was finished on the cross . . .
When the last soul is saved by His grace, the end will come; this earth will be destroyed with fire; Judgement Day will manifest destinies, Satan and all wicked men will be cast into hell; the new heavens and new earth will be brought forth and Christ and His church will inherit the glory of this kingdom, and live as One, forever and ever.
Do you believe the righteous rise to heaven, or do you think they lay away and sleep until Judgement Day?
It seems you already hold dual views.
