This part of John's vision of the city shows how God provides water and food for his people (compare Exodus 16:4, 22–24; Ezekiel 47:1–12; John 4:10; 6:32–35). God first created a "garden of delight" (Eden) for Adam and Eve, but they disobeyed him and lost it (Genesis 2–3). Now, Eden is remade and joined with the heavenly city as God's wonderful gift for his faithful people.
