Jeremiah 17:8
8. (Ps 1:3).
shall not see—that is, feel. Answering to Jer 17:6; whereas the unbelievers "shall not see (even) when good cometh," the believer "shall not see (so as to be overwhelmed by it even) when heat (fiery trial) cometh." Trials shall come upon him as on all, nay, upon him especially (Heb 12:6); but he shall not sink under them, because the Lord is his secret strength, just as the "roots spread out by a river" (or, "water-course") draw hidden support from it (2Co 4:8-11). careful—anxious, as one desponding (Lu 12:29; 1Pe 5:7). drought—literally, "withholding," namely, of rain (Jer 14:1); he here probably alludes to the drought which had prevailed, but makes it the type of all kinds of distress. John 4:13-14
13, 14. thirst again . . . never thirst, &c.—The contrast here is fundamental and all comprehensive. "This water" plainly means "this natural water and all satisfactions of a like earthly and perishable nature." Coming to us from without, and reaching only the superficial parts of our nature, they are soon spent, and need to be anew supplied as much as if we had never experienced them before, while the deeper wants of our being are not reached by them at all; whereas the "water" that Christ gives—spiritual life—is struck out of the very depths of our being, making the soul not a cistern, for holding water poured into it from without, but a fountain (the word had been better so rendered, to distinguish it from the word rendered "well" in Joh 4:11), springing, gushing, bubbling up and flowing forth within us, ever fresh, ever living. The indwelling of the Holy Ghost as the Spirit of Christ is the secret of this life with all its enduring energies and satisfactions, as is expressly said (Joh 7:37-39). "Never thirsting," then, means simply that such souls have the supplies at home.
into everlasting life—carrying the thoughts up from the eternal freshness and vitality of these waters to the great ocean in which they have their confluence. "Thither may I arrive!" [BENGEL]. John 7:38-39
38. as the scripture hath said—These words belong to what follows, "Out of his belly, as the scripture hath said, shall flow," &c. referring not to any particular passage, but to such as Isa 58:11; Joe 3:18; Zec 14:8; Eze 47:1-12; in most of which the idea is that of waters issuing from beneath the temple, to which our Lord compares Himself and those who believe in Him.
out of his belly—that is, his inner man, his soul, as in Pr 20:27. rivers of living water—(See on Joh 4:13). It refers primarily to the copiousness, but indirectly also to the diffusiveness, of this living water to the good of 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.
