The gospel of John

We've been studying John lately so I've spent more time reading it. Interesting things pop out when you read something thoughtfully a couple times. Today I was noticing the prominence of water in this gospel:

Water in the Gospel of John

Chapter	Description
1	John's baptism (compared with baptism with the Holy Spirit)
2	Jesus turns water into wine
3	Nicodemus: need to be born of water and of the Spirit
-	Mention of baptising by John and Jesus (or his disciples)
-	Questions about purifying (done with water)
4	Baptizing by disciples of Jesus
-	Jacob's well and the living water (which is the Spirit)
5	Pool at Bethesda, used for healing
6	Jesus walks on water
7	Jesus tells all who thirst to come to Him and drink (water is the Spirit)
9	Blind man receives sight when he washes the mud that Jesus placed on his eyes
10	John the Baptist, where he baptized, and his testimony are mentioned
11	Mention of purification (verse 55)
13	Jesus washes the disciples feet

So we'll see if I can make sense of these references at a later date.
