"The river of the water of life is symbolic of a profuse and constant flow of life, of the continuous operation of the life-giving spirit of God in Christ and in all who are made one in Him. The glorified saints receive and appropriate this divine flow of life, and they also become a source of its life-giving properties for all men and all creation."
