Ісая 55:8

The appeal, to leave their own way and their own thoughts, and yield themselves to God the Redeemer, and to His word, is now urged on the ground of the heaven-wide difference between the ways and thoughts of this God and the despairing thoughts of men (Isa 40:27; Isa 49:24), and their aimless labyrinthine ways. "For my thoughts are not your thoughts, neither are your ways my ways, saith Jehovah: no, heaven is high above the earth; so high are my ways above your ways, and my thoughts above your thoughts." The kı̄ (imo) introduces the undeniable statement of a fact patent to the senses, for the purpose of clearly setting forth, by way of comparison, the relation in which the ways and thoughts of God stand to those of man. There is no necessity to supply כאשׁר after כּי, as Hitzig and Knobel do. It is simply omitted, as in Isa 62:5 and Jer 3:20, or like כּן in Pro 26:11, etc. On what side the heaven-wide elevation is to be seen, is shown in what follows. They are not so fickle, so unreliable, or so powerless.

As we had much of Christ in the 53rd chapter, and much of the church of Christ in the 54th chapter, so in this chapter we have much of the covenant of grace made with us in Christ. The "sure mercies of David," which are promised here (Isa 55:3), are applied by the apostle to the benefits which flow to us from the resurrection of Christ (Act 13:34), which may serve as a key to this chapter; not but that it was intended for the comfort of the people of God that lived then, especially of the captives in Babylon, and others of the dispersed of Israel; but unto us was this gospel preached as well as unto them, and much more clearly and fully in the New Testament. Here is, I. A free and gracious invitation to all to come and take the benefit of gospel grace (Isa 55:1). II. Pressing arguments to enforce this invitation (Isa 55:2-4). III. A promise of the success of this invitation among the Gentiles (Isa 55:5). IV. An exhortation to repentance and reformation, with great encouragement given to hope for pardon thereupon (Isa 55:6-9). V. The ratification of all this, with the certain efficacy of the word of God (Isa 55:10, Isa 55:11). And a particular instance of the accomplishment of it in the return of the Jews out of their captivity, which was intended for a sign of the accomplishment of all these other promises.

55:8-9 My thoughts are nothing like your thoughts: God’s plans are marvelous (Ps 92:5; cp. Ps 94:11). God’s creatures, including humans, can never fully understand the Creator’s thoughts, but his revelation through his messengers gives great insight and knowledge of some of the things he will do.
