In Rev. 22:1-5, John completes his description of the New Jerusalem. This passage identifies three basic things necessary for life: water, food, and health. John tells us that in the New Jerusalem there will be an abundance of each of these three commodities. We will drink from the River of Life; we will eat from the Tree of Life; and we will be enjoy health and prosperity simply by touching the leaves of the Tree of Life. In the New Jerusalem, God will fully satisfy all the needs of his people.
