Christ is the Tree of Life
The scene [Rev 22:1-3] described by John calls to mind essential features of Eden: the tree of life and the river of life, which, according to Genesis 2: 10, flowed out of Eden. In this new Eden, all those whose sin has been dealt with on the tree of Calvary not only drink freely from the river of life; they eat freely from the tree of life. As we look closely, we can’t help but recognize that this life-giving, forever-feeding, healing tree is none other than Christ himself. 12 “In him was life” John wrote (John 1: 4). And in a sense, this is what Jesus meant during his earthly ministry when he said, “Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever feeds on my flesh and drinks my blood has eternal life, and I will raise him up on the last day” (John 6: 53- 54).
