A study of Revelation chapter 22, heaven and the New Jerusalem. We consider the eternal resources of the river of life and the tree of life. It would perhaps be easy to forget that either the tree of life or that river of life ever existed. Once they were in Eden, but since Genesis chapter 3 Adam and humanity have been barred from entrance into that garden and resource. Down through the scriptures that river has not been forgotten about. The nation of Israel drank of that river in the wilderness (1 Corinthians chapter 10); David thirsted for that river (Psalm 42 verse 1) and knew of the source of that river (Psalm 46 vs 4). The woman at the well in John chapter 4 tasted of that living water. Here is the source of that living water in Revelation chapter 22. There are two conditions attached to enjoing that living water. It comes from the throne of God and of the Lamb. We must know Him as Lord and as Saviour and then we can taste of that Living Water. What is holding us back? The resources for spiritual progress is all there. Dr J Stewart Gillespie From a systematic study in the Book of Revelation Bridgend Gospel Hall New Cumnock
