John 4:14

But whoever drinks the water that I give him will never be thirsty again.  But the water that I give him will become in him a spring of water (satisfying his thirst for God) welling up (continually flowing, bubbling within him) to eternal life.  

Have you ever talked to someone who doesn’t know Jesus, and they feel dissatisfied on the inside and don’t know why?  They don’t understand the soul and its connection to God.  They may seek to find what they are missing in many ways but always seem to come up short.  The only thing that will ever satisfy is the living waters of Jesus.
