"37 On the last day of the feast, the great day, Jesus stood up and cried out, “If anyone thirsts, let him come to me and drink. 38 Whoever believes in me, as the Scripture has said, ‘Out of his heart will flow rivers of living water.’”39 Now this he said about the Spirit, whom those who believed in him were to receive, for as yet the Spirit had not been given, because Jesus was not yet glorified.
40 When they heard these words, some of the people said, “This really is the Prophet.” 41 Others said, “This is the Christ.” But some said, “Is the Christ to come from Galilee? 42 Has not the Scripture said that the Christ comes from the offspring of David, and comes from Bethlehem, the village where David was?” 43 So there was a division among the people over him. 44 Some of them wanted to arrest him, but no one laid hands on him."
John 7:37-44
Some further points in these verses call for comment before we leave them. The reference to the scripture in 38 has puzzled commentators, as no specific passage of the Old Testament can be cited, but cf Zechariah 13:1, 14:8; Isaiah 44:3, 55:1, 58:11, which certainly give substance to our Lord's words here. John's comment in 39 is even more significant: 'This spake He of the Spirit'. The Spirit, then can be spoken about when He is not specifically referred to by Name! This is a salutary reminder, and we have a very excellent example of this in Paul's letters to the Ephesians and the Colossians, in which the name of the Spirit is hardly mentioned, but His presence, working and power are everywhere evident. John next goes on to say 'which they that believe on Him should receive' - that is, saving faith appropriates the Spirit, and this is what opens up a well of water within us. Deeply interesting also are the words which follow: 'The Spirit was not yet given, because Jesus was not yet glorified'. One commentator properly points out that this is a theological, rather than a chronological, statement, and it does not mean that the Spirit was not at work in the disciples' lives before Pentecost. Statements such as that in Mark 12:36 surely make it abundantly plain that the Spirit was at work even in the Old Testament dispensation, let alone among the disciples of our Lord before Pentecost. Theologically, however, and dispensationally, the Spirit could not have been as yet given, since Jesus had not yet accomplished the work on which the giving of the Spirit depended. In the spiritual sense, however - and this bears a message of great import for us - the dispensational order holds good: there can be no endowment of the Spirit until Jesus is glorified in a believer's life. 'No cross, no crown' is an unfailing principle in spiritual experience.
