God is the ultimate giver and saver of life, and is described here in Ezekiel’s vision of the river of life as, "the giver of healing water from His throne" (47:1–12).
This recurring image in prophecy can also be found in Revelation 22:1–2. In those verses, the Apostle John also describes the “River of Life,” flowing from the throne of God and is of the Lamb (Jesus Christ). Also, on either side of the river, is the "Tree of Life," which bore twelve fruits, each tree yielding its fruit every month, and the leaves of the tree were for the healing of the nations.
Throughout scripture, "the lamb" is always a reference to Jesus. It was His sacrifice on the cross that made atonement for our sin. And because of that, Jesus is often referred to as, "the sacrificial lamb." Scripture also makes note of the fact that during His crucifixion, a sword was thrust into His side to make sure He was dead, and out of it (His side, His body) flowed blood and water.
This makes John's reference of, "the River of Life, flowing from the throne of God and of the Lamb" (Jesus Christ), very interesting indeed. For we see this very river, with healing waters, coming from the temple (God's Throne room) foretold by Ezekiel, here in chapter 47. In both references, the water’s main properties are that it heals and gives life, suggesting a renewal of not just the physical creation, but spiritual vitality as well.
The Truth: Christ Himself is the Living Water: “Whoever drinks the water I give him will never thirst. Indeed, the water I give him will become in him a spring of water welling up to eternal life” (John 4:7–14).
