What does living water mean in the Bible?

In John 4, Jesus speaks of living water when conversing with the Samaritan woman, indicating the sustenance and regeneration that only He can provide. In John 7:37-39, living water is defined as the Holy Spirit, who is given to believers after Christ’s glorification. This living water symbolizes not only spiritual nourishment but also the transformative power that brings about eternal life. It contrasts the physical water from Jacob's well, emphasizing that true satisfaction and life come from Him alone.
