When was the last time you heard a message or song about the New Earth? Yes, it is in your Bible! It is also one of the most eternally blessed, yet theologically ignored topics ever. The idea of "heaven" being good and earth being bad is as preposterous as believing that your spirit is good, but your mind, will, emotions, and body are evil. Dualism curses that which is visible and tangible. God doesn't! He cherishes the terrestrial and uses it to give expression to the celestial! That's exactly why the Word became flesh and "moved into the neighborhood"!
The Incarnation is far more than a "Christmas Story". There is a visible, tangible, flesh and bone, incarnate representative of all mankind seated at the right hand of the Father! In Him, we are wonderfully intertwined with the Trinity and each other! Heaven is the realm of the Spirit...available to earth and presently dwelling within us. We've been taught to believe for better bodies, but not a better planet. That is erroneous.
Rev. 21:1-3 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God. (See also Is. 65:17, Is. 66:22 & 2 Pet. 3:13)
I believe that the experience of the above verses can be greatly enjoyed today, with greater expressions to come...
