We were not created for the ultimate purpose of becoming disembodied spirits who live in a far away place in the sky called, "heaven". Our final inheritance and destination is a much better earth and our final, eternal form will be a glorified, immortal body...just like the one Jesus has! The meek shall inherit THE EARTH!
Our mission, by His Grace, is to unceasingly participate in the coming of His Kingdom while fleshing out His Will on earth (visible realm) as it is in heaven (invisible/spirit realm).
The imminent sign of His ultimate, physical appearing (unlike prophecies concerning 70 AD...i.e.- Mt. 24, Revelation, etc...) will be an Earth that resembles Heaven so strongly (SO MUCH LOVE!)...that the only missing ingredient will be His Physical return. Yes, He will feel "at home"!
The problem with much Western Christian belief is that it has people longing to be disembodied spirits in the sky, when Jesus longs to physically inhabit the earth again...WORLD WITHOUT END. It also leaves the earth with no ever-increasing/coming Kingdom and no meek people to inherit it!
Jesus' resurrection required a glorified, immortal, physical body. So will ours, along with the souls of all who have preceded us in death! Resurrection requires a BODY. Where there is no body, there is no resurrection!
What about the phrase, "Heaven and Earth shall pass away"? Any First Century Jew could tell you that "Heaven and Earth" was an extremely common reference to the temple and physical Jerusalem....which were destroyed in 70 AD.
What New Covenant "Temple" replaced the one that was destroyed? The answer to that question reveals the identity of the "New Heaven", the "New Earth", and the "New Jerusalem"...which John saw coming DOWN to EARTH!
Hint: 1 Corinthians 6:19,20.
The Future: Glorified bodies on a perfect earth! Better than Adam & Eve and better than the original Garden!
