"Heaven is not some thin place, some cosmic hyperbaric chamber for disembodied spirits only. It is realer, truer, grander. Lewis may have captured the best illustrative parallel of how heaven “works” with his Narnia stories. Narnia is a real place with its own time, space, matter, contents. Narnia is bigger than our world but nevertheless within our world, or at least accessible within our world. It is not outer space, it is inner space but outsized space. Bigger inside than it looks outside.
The new heavens and new earth will make this place more colorful, not less. Thicker, realer, truer, better."
