How do we know Jesus is the living water?

In John 4, Jesus reveals Himself to the Samaritan woman at the well as the source of living water. He explains that whoever drinks of the water He gives will never thirst again (John 4:14). This declaration underscores His role as the fulfillment of every spiritual need and the ultimate source of life. When He invites the thirsty to come to Him and drink (John 7:37), it demonstrates His willingness to provide for our deepest needs. Thus, through Jesus' life, teachings, and the fulfillment of prophecy, we see the truth of His identity as the living water.
