Revelation 4:Then the angel showed me a river of the water of life, as clear as crystal, flowing from the throne of God and of the Lamb down the middle of the main street of the city. On either side of the river stood a tree of life, producing twelve kinds of fruit and yielding a fresh crop for each month. And the leaves of the tree are for the healing of the nations... And there will no longer be any night; and they [d]will not have need of the light of a lamp nor the light of the sun, because the Lord God will illumine them; and they will reign forever and ever.
In the Egyptian Book of the Dead when the sun god enters the netherworld he brings light("Illumines") and raises the dead there. The dead are then judged by Osiris who sits on a throne that has water flowing under it. In the photo below you'll notice under the throne is blue with wavy lines which indicates water. You'll notice coming out of the water is a lotus flower(represents resurrection) with four beings standing on the flower. These four beings are known as the sons of Horus. Three of them were often portrayed as having the heads of animals while one of them had the head of a man. One has the head of an Eagle, one the head of a baboon(which resembles a lion in the picture), and the other the head of a Jackal(which resembles a calf in the picture). When the dead first enter the netherworld they are given food from the Tree of Life by the Goddess Nut....and before the throne there was something like a sea of glass, like crystal; and in the [c]center and around the throne, four living creatures full of eyes in front and behind. 7 The first creature was like a lion, and the second creature like a calf, and the third creature had a face like that of a man, and the fourth creature was like a flying eagle.
