God knows our deepest needs and wants to meet our deepest needs. Ever since Genesis 3, we keep trying to meet these needs with idolatrous substitutes. But God in his love, sent Jesus to seek and save the lost. In this story, Jesus gently and firmly shows the Samaritan woman that the only one able to meet her needs is God. The thirst she has for the water of life can only be quenched in a personal encounter with God through the Messiah which is what worship is all about.
