How do we know Christ is the fountain of living water?

The identification of Christ as the fountain of living water is established in various scriptures. In Jeremiah 2:13, the Lord contrasts Himself as the 'fountain of living waters' against forsaken cisterns, illustrating the insufficiency of other religious or human efforts for salvation. Additionally, in John 7:37-39, Jesus invites the thirsty to come to Him, expressing that those who believe in Him will receive streams of living water. This deep-rooted connection is further illuminated in the context of Zechariah 13:1, which reveals the purpose of this fountain as a source of cleansing for sin and uncleanness. Thus, Christ stands as the sole source of spiritual life and purity, validated by both Old and New Testament teachings.
