John 7:37-39New Century Version (NCV)
Jesus Talks About the Spirit
37 On the last and most important day of the feast Jesus stood up and said in a loud voice, “Let anyone who is thirsty come to me and drink. 38 If anyone believes in me, rivers of living water will flow out from that person’s heart, as the Scripture says.” 39 Jesus was talking about the Holy Spirit. The Spirit had not yet been given, because Jesus had not yet been raised to glory. But later, those who believed in Jesus would receive the Spirit.
