Water in the book of John

I heard a recent sermon by the author of "the other side of the lake." As an aside, I guess it was, he mentioned the importance of water in the book of John. So I checked it out. I found that there were at least the following references to water:

In John 1, there is a discussion of the baptism of John the Baptist, which was with water.

In John 2, Jesus performed His first miracle, namely turning water into wine.

In John 3, Jesus told Nicodemus that one must be born of both water and the Spirit, and there is more about John the Baptist's baptism with water.

In John 4, Jesus met a woman of Samaria at the well, where she had come to draw water. Jesus said that He was an unending source of water.

In John 5, Jesus healed a man, who was lying by the pool of Bethesda.

In John 6, Jesus walked on the sea during a storm.

In John 7, Jesus proclaimed Himself as the source of living water.

I didn't find a mention of water in John 8.

In John 9, Jesus told a blind man to wash in the pool of Siloam.

In John 10, Jesus crossed the Jordan River.

In John 11, Jesus wept.

I didn't find water mentioned in John 12.

In John 13, Jesus washed the disciples' feet.

I didn't find water mentioned in John 13 through 18.

In John 19, blood and water came out of Jesus' side, when it was pierced.

I didn't find water mentioned in John 20.

In John 21 (the last chapter) Jesus met his disciples by the sea.

Water is an amazing and very important substance. It makes sense to believe that God's original blueprint for the universe included a special role for this combination of Hydrogen and Oxygen atoms, and that he designed them in such a way that they could carry out this special role. I don't think it's possible to prove that, though.

Thanks for the suggestion, other side! Thanks for reading.
