After John witnesses the new heaven and a new earth "that no longer has any sea", an angel takes him "in the Spirit" to a vantage point on "a great and high mountain" to see New Jerusalem's descendants. The enormous city comes out of heaven down to the New Earth. John's elaborate description of the New Jerusalem retains many features of the Garden of Eden and the paradise garden, such as rivers, a square shape, a wall, and the Tree of Life.
