Isaiah 55:8

“For my thoughts are not your thoughts, &c.] In some things there may be a likeness between the thoughts of God and the thoughts of men, as to the nature of them: thoughts are natural and essential to them both; they are within them, are internal acts, and unknown to others, till made known; but then the thoughts of men are finite and limited, whereas the thoughts of the Lord are infinite and boundless; men’s thoughts have a beginning, but the Lord’s have none; though not so much the nature as the quality of them is here intended: the thoughts of men are evil, even the imagination of their thoughts, yea, every imagination is, and that always and only so; but the thoughts of God are holy, as…”

“For--referring to Isa 55:7. You need not doubt His willingness "abundantly to pardon" (compare Isa 55:12); for, though "the wicked" man's "ways," and "the unrighteous man's thoughts," are so aggravated as to seem unpardonable, God's "thoughts" and "ways" in pardoning are not regulated by the proportion of the former, as man's would be towards his fellow man who offended him; compare the "for" (Psa 25:11; Rom 5:19).”

“For my thoughts are not your thoughts - Interpreters have differed in regard to the connection of this verse with the preceding. It is evident, I think, that it is properly connected with the subject of pardon; and the sense must be, that the plans and purposes of God in regard to forgiveness are as far above those of people as the heavens are higher than the earth, Isaiah 55:9. But in what respects his plan of pardon differs from those of people, the prophet does not intimate, and can be understood only by the views which are presented in other parts of the Bible. The connection here would seem to demand some such view as the following: 1. People find it difficult to pardon at all. They…”

“For - If any man injure you, especially if he do it greatly and frequently, you are slow and backward to forgive him. But I am ready to forgive all penitents, how many, and great, and numberless soever their sins be. Isaiah 55:10”

“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.”

“Sa2 7:19; Psa 25:10, Psa 40:5, Psa 92:5; Pro 21:8, Pro 25:3; Jer 3:1; Eze 18:29; Dan 4:37; Hos 14:9 Isaiah 55:9”

“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…”
