7:37-39 On the last day of the feast of tabernacles, the Jews drew water and poured it out before the Lord. It is supposed that Christ alluded to this. If any man desires to be truly and for ever happy, let him apply to Christ, and be ruled by him. This thirst means strong desires after spiritual blessings, which nothing else can satisfy; so the sanctifying and comforting influences of the Holy Spirit, were intended by the waters which Jesus called on them to come to Him and drink. The comfort flows plentifully and constantly as a river; strong as a stream to bear down the opposition of doubts and fears. There is a fulness in Christ, of grace for grace. The Spirit dwelling and working in believers, is as a fountain of living, running water, out of which plentiful streams flow, cooling and cleansing as water. The miraculous gifts of the Holy Spirit we do not expect, but for his more common and more valuable influences we may apply. These streams have flowed from our glorified Redeemer, down to this age, and to the remote corners of the earth. May we be anxious to make them known to others.

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.
