The New Jerusalem in the Book of Revelation

There is a development between expectation for the rebuilding of the New Jerusalem/Temple in the Old Testament and the coming of the New Jerusalem/Temple in Revelation. In Revelation, there is a dynamic relation between the New Jerusalem and the Heavenly Jerusalem: the New Jerusalem is the descent of the Heavenly Jerusalem. Moreover, there is no Temple building which was expected as the eschatological promise in the Old Testament but rather God and the Lamb is the Temple. How can this shift be explained? Pilchan Lee examines the exegetical tradition which existed between the Old Testament and Revelation. He assumes that as the exegetical tradition, the early Jewish (apocalyptic) literature functions as a key element for forming the idea of the New Jerusalem in Revelation. John¿s main argument is that the church (which is symbolized by several images) is placed in heaven now (chapters 4-20) and the church (which is symbolized by the New Jerusalem) will descend to the earth from heaven in the future (21-22).
