What does the “living water” have to do with Jesus?

A tradition grew up in the few centuries before Jesus on the 7 days of the Feast of Tabernacles. A gold container filled with water from the pool of Siloam was carried in procession by the high priest back to the temple. As the procession came to the Watergate on the south side of the inner temple court, 3 trumpet blasts were made to mark the joy of the occasion and the people recited Isaiah 12:3, “With joy you will draw water from the wells of salvation.” At the temple, while onlookers watched, the priests would march around the altar with the water container while the temple choir sang the Hallel (Pss. 113-118). The water was offered in sacrifice to God at the time of the morning sacrifice. The use of the water symbolized the blessing of adequate rainfall for crops.

In John 7:37, Jesus used this event as an object lesson and opportunity to make a very public invitation on the last day of the feast for His people to accept Him as the living water. His words recall Isaiah 55:1. “If anyone thirsts, let him come to me and drink.” These 3 words summarize the gospel invitation. A recognition of need leads to an approach to the source of provision, followed by receiving what is needed. The thirsty, needy soul feels the craving to come to the Savior and drink, i.e., receive the salvation that He offers.

“Out of his heart will flow rivers of living water” (v. 38). The water-pouring rite was also associated with Jewish tradition as a foreshadowing of the eschatological rivers of living water foreseen in Ezekiel 47:1-9 and Zechariah 13:1. The significance of Jesus’ invitation centers in the fact that He was the fulfillment of all the Feast of Tabernacles anticipated, i.e., He was the One who provided the living water that gives eternal life to man (4:10, 11). By this “He spoke concerning the Spirit” (v. 39). The impartation of the Holy Spirit is the source of spiritual and eternal life.
