Against the backdrop of the Temple, the Good Shepherd promises to give living water to anyone who is thirsty and believes in him (John 7:37-38). The Jews around the Temple mount at the Feast of Tabernacles (Sukkoth) would have understood this to symbolize ritual cleansing.
Everyone entering the Temple needed to bathe by immersion.
The entire southern slope up to the Temple entrance was
developed with a system of canals, channels, and cisterns
(visible today as a result of excavation), so that all Temple-
goers might make themselves clean during this final ascent
into the presence of the Holy One of Israel (Rabbi Jesus, p. 27).
An article, titled “Joy of Living Water” at Follow the Rabbi, makes this point:
There was another special element to the celebration of Sukkot,It would seem from this perspective that Jesus was not only promising to cleanse, but that he was also promising water for regeneration, as in the rebirth of the crops. The online article goes on to say, “The importance of the Jewish background to Jesus' work cannot be exaggerated. It gave him the context he needed to make his teachings relevant, powerful, and practical.”
and it involved living water. Sukkot took place at the end of the
dry season. The rains needed to begin immediately to ensure a
harvest the following year. Thus the celebration of God's
harvest was coupled with fervent prayer for next year's rains.
Relevant, powerful and practical both then and now.
Thank you Lord for the streams of living water making me grow like a tree and helping to produce fruit in season (Psalm 1:3).
