Water of Life (Christianity)
In Christianity the term "water of Life" (Greek: ὕδωρ ζωῆς hydōr zōēs) is used in the context of living water, specific references appearing in the Book of Revelation (21:6 and 22:1), as well as the Gospel of John. In these references, the term Water of Life refers to the Holy Spirit.
The Book of Revelation
- "I will give unto him that is athirst of the fountain of the water of life freely". Revelation 22:1 then states: "And he showed me a river of water of life, bright as crystal, proceeding out of the throne of God and of the Lamb" .
The common theme of thirst for the Water of Life in the Book of Revelation and the Gospel of John may be summarized as follows: 
|Revelation 21:6||John 7:37||John 4:14|
|... to the thirsty I will freely give from the fountain of the water of life.||... if any man thirsts, let him come unto me and drink.||... the water that I shall give him shall become in him a well of water springing up unto eternal life.|
The use of the term Water of Life in Revelation 20 is part of the "theme of life" in the book of Revelation, other instances being the Book of Life in Revelation 21:27, and the Tree of Life in 22:2, 22:14 and 22:19. John R. W. Stott relates this theme to Eternal Life in John 17:3: "And this is life eternal, that they should know thee the only true God, and him whom thou didst send, Jesus Christ".
The Gospel of John
The passages that comprise John 4:10–26, and relate the episode of the Samaritan woman are sometimes referred to as the "Water of Life Discourse". The Water of Life Discourse is the second among the seven discourses in the Gospel of John that pair with the seven signs in that gospel.
Another discourse, called the Bread of Life Discourse appears in John 6:22–59. On their own, each of the discourses on the Water of Life and the Bread of Life are key examples of "single theme discourses" in the Gospel of John. However, these two discourses in the Gospel of John complement each other to form the theme of "Christ as the Life".
According to W. E. Vine, this theme of "Christ as the Life" relates to John 5:26 where Jesus states: "Just as the Father has life in himself, so also he gave to his Son the possession of life in himself", reflecting the assertion of Jesus to have the power to give life, based on his relationship to the Eternal Father.
