<p>22:1- see on Jn. 1:14.</p><p><em>And he showed me a river of water of life, bright as crystal, proceeding out of the throne of God and of the Lamb</em>- The throne of God and Jesus will be in Jerusalem. The river of life proceeds from there. Whilst I fail to see a doctrine of a Millennial reign taught in Revelation, it's clear that after Babylon is destroyed and Christ and the saints are enthroned in Jerusalem, there is a period of time during which the surviving mortals have the opportunity to identify themselves with the Kingdom and be immortalized. The water of life thus flows out to them, and they are urged to drink freely of it, thereby finding immortality. Likewise the tree of eternal life offers its fruits to them in :2; all they have to do is take it. And both the Lord Jesus and us His bride urge the peoples to come into the city of God, through the gates into the city of eternal life (:17). It may be that in order to eat of the tree of life they must first &quot;wash their robes&quot;, undergoing a kind of baptism experience (:14). There may be some literal element of fulfilment of the prophecy that a fountain will be opened in Jerusalem where sin can be cleansed (Zech. 13:1).</p>
