39. this spake he of the Spirit--who, by His direct personal agency, opens up this spring of living waters in the human spirit (Joh 3:6), and by His indwelling in the renewed soul ensures their unfailing flow.
      they that believe, &c.--As the Holy Ghost is, in the redemption of man, entirely at the service of Christ, as His Agent, so it is only in believing connection with Christ that any one "receives" the Spirit.
      for the Holy Ghost was not yet given--Beyond all doubt the word "given," or some similar word, is the right supplement. In Joh 16:7 the Holy Ghost is represented not only as the gift of Christ, but a gift the communication of which was dependent upon His own departure to the Father. Now as Christ was not yet gone, so the Holy Ghost was not yet given.
      Jesus not yet glorified--The word "glorified" is here used advisedly, to teach the reader not only that the departure of Christ to the Father was indispensable to the giving of the Spirit, but that this illustrious Gift, direct from the hands of the ascended Saviour, was God's intimation to the world that He whom it had cast out, crucified, and slain, was "His Elect, in whom His soul delighted," and that it was through the smiting of that Rock that the waters of the Spirit--for which the Church was waiting, and with pomp at the feast of tabernacles proclaiming its expectation--had gushed forth upon a thirsty world.
