The New Heaven and New Earth

There is a growing focus on the Christian confession of God's completed kingdom, the new heaven and the new earth. This theme has time and again seduced people into elaborate fantasies that stimulated the senses. How can we talk about it meaningfully?
Raymond R. Hausoul relates systematic theology to biblical theology by comparing three theologians: the Catholic theologian Karl Rahner, the Protestant Jurgen Moltmann, and the Reformed Gregory Beale. This leads to reflections on differences between matter, space, and time of the new heaven and new earth and those of our present reality. The hope for renewal and resurrection is thus linked to the prophecies of the new Jerusalem, the tree of life, and the resurrection body.
