"If anyone thirsts, let him come to me and drink” (v37). Jesus declared that he was not another traveling philosopher or holy prophet; he came from the Father, and he offered “living water” to those who were dying of thirst. While the religious authorities persecuted him, people who recognized their need believed in him (v39-49). Jesus wasn’t starting a new political party or trying to gain control of a society; he was giving the whole dying world a chance at forgiveness and life.
“Whoever believes in me … out of his heart will flow rivers of living water” (v38). The gospel is not just information about Jesus, it is the opportunity to receive his life-giving Spirit into our hearts.
