6/5/10 John’s angel guide now shows John inside the city of which the most prominent feature is the river of life and the tree of life. The river flows from the throne of God like the river that Ezekiel saw in chapter 47. There the river was a trickle at the gate of the temple then got progressively deeper.
On either side of the river in Ezekiel were lots of trees, whereas in Revelation one tree is growing on both sides of the river. The tree bears 12 kinds of fruit. This may simply represent the abundance and perfection of the tree and its life-giving qualities, or perhaps it also literally has a different fruit each month for 12 months.
The leaves of the tree are for the healing of the nations. This may be symbolic for the overall situation of peace, comfort, and all necessities of life for God’s people. The Genesis curse on the land will no longer exist. God will dwell there and his people will willingly and joyfully serve and worship him.
His name on their foreheads represents their total consecration to God as well as their characters being like him.
Because God’s glory is there the sun and the moon will be background, fading into the light of God. God himself will illumine his people.
Also they shall reign forever. This no doubt means something about the work God has planned for us, but it may also be understood that we will live like kings. All needs will be cared for.
