From Within Him Will Flow Rivers of Living Water
Jesus promises Spirit-given life that overflows.
Jesus invites the thirsty to come to him, promising an inward overflow that John interprets as the gift of the Spirit.
Scripture
John 7:37-39
37 Now on the last and greatest day of the feast, Jesus stood and cried out, "If anyone is thirsty, let him come to me and drink!
38 He who believes in me, as the Scripture has said, from within him will flow rivers of living water."
39 But he said this about the Spirit, which those believing in him were to receive. For the Holy Spirit was not yet given, because Jesus wasn't yet glorified.
