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.

Rivers partake of the character of the source from which they come that which proceeds "out of the throne of God and of the Lamb "may well be "a pure river of water of life, clear as crystal." What but good and perfect gifts can come down from the throne of God? What but pure streams of mercy can flow from the throne of the Lamb?
