"Everyone who drinks this water will be thirsty again, but whoever drinks the water I give him will never thirst. Indeed, the water I give him will become in him a spring of water welling up to eternal life."

"If anyone is thirsty, let him come to me and drink. Whoever believes in me ... streams of living water will flow from within him." By this he meant the Spirit.

(John 4:13-14 & 7:37-39 NIV)
