Revelation 22:1

But just as the waters of the deep are tamed as they flow from the throne of God in the New Jerusalem as a resource for eternal life, so also in the book of Revelation the magnificence of water is inherent in the voice of the heavenly Christ. His Word forever gives life, like life-giving streams:

This is the spiritual water of life that anyone who is thirsty for God's Truth may receive as a gift.

Evil men may for a short time be allowed to take away the physical blessing of water, freely given by God, however, they cannot touch the far more important spiritual water of life.

Revelation 22:1

Not only does judgment proceed from the throne of God, but also salvation and eternal life. There is a good, perfect balance of His severity and His goodness; and that is something that a perfect Judge must have - the proper balance of severity and goodness. On the one hand, you have this burning river coming from the throne, in which the Beast and the false prophet are thrown (as it mentions there in Daniel 7). But also emanating from the throne is the river of the water of Life. It shows the two sides - the severity and the goodness - of God. They both begin at His throne.
