John 7:37-39 - The Promise Of The Spirit
37 On the last day, the great day of the feast, Jesus stood and shouted in a loud voice: If any man thirst let him come to me and drink. 38 Rivers of living water will flow from the innermost being of the man who believes in me. This is according to the scriptures. 39 He spoke this by the Spirit. Those who believed in him were to receive the Spirit. The Spirit was not yet given because Jesus was not yet glorified.
