Revelation 22:1

Revelation 22:1. And he shewed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the lamb.

There is no other "water of life" except that which springs from a Sovereign God and a substitutionary sacrifice: "a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb." This sets forth the blessings of salvation that come to us through the Sovereign grace of God by the precious blood of Jesus.
