“It was the last and most important day of the Feast. Jesus stood up and spoke in a loud voice. He said, "Let anyone who is thirsty come to me and drink. Does anyone believe in me? Then, just as Scripture says, streams of living water will flow from inside him." When he said this, he meant the Holy Spirit. Those who believed in Jesus would receive the Spirit later. Up to that time, the Spirit had not been given. This was because Jesus had not yet received glory.” (John 7:37-39)
“You see, at just the right time, when we were still powerless, Christ died for the ungodly. Very rarely will anyone die for a righteous person, though for a good person someone might possibly dare to die. But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.” (Romans 5:6-8)
Jesus is the well of the living water, the Holy Spirit.
