The very first book of the Bible opens with an image of that mysterious tree standing majestically in the Garden of Eden in Genesis 3. After the Fall, it fades from view as Adam and Eve are evicted from Eden lest they eat from the Tree and live forever in their corrupted condition. The Tree of Life turns up again only at the very end of the Bible. Revelation 22 describes it standing alongside the River of Life, bearing 12 kinds of fruit year round. In fact, if you read the chapter carefully, it seems the tree has multiplied and produced an orchard of life.
