This book concerns itself with what Jesus truly has to say about natural Israel, natural land in Palestine, a natural temple, and a natural city called Jerusalem. As the author of Hebrews says of all in the Church, "We have not come to a mountain that can be touched....We have now come unto Mount Zion, to the heavenly Jerusalem and the City of the living God...to thousands upon thousands of angels in joyful assembly; to the Church of the firstborn-ones whose names have been written in heaven" (12:18, 22-23).
