John 7:37-39 - The Promise Of The Spirit
37 Now on the last day, the great day of the feast, Jesus had stood and cried out, saying, If any man thirsts, let him come to me and drink. 38 He who believes in me, as the scripture has said, out of his belly will flow rivers of living water. 39 But he spoke this about the Spirit that those who believe in him were going to receive, for Holy Spirit was not yet, because Jesus was not yet glorified.
