Isaiah 43:25

“I, even I am he, that blotteth out thy transgressions for mine own sake, &c.] The same with “sins” in the next clause; original sin, and actual sins; which are transgressions of the law of God, of which the law accuses, for which it pronounces guilty, curses, and condemns; which are contrary to the nature of God, strike at his deity, and must be abominable to him; they are many, yea infinite, and yet all pardoned for Christ’s sake; which is here expressed by a “blotting” them out, in allusion to the blotting of a debt book: sins are debts, and these are many, and which cannot be paid by the sinner; Christ has made full payment; as the surety of his people: upon this the debt book is crossed;…”

“I, even I--the God against whom your sin is committed, and who alone can and will pardon. (Isa 44:22). for mine own sake-- (Isa 48:9, Isa 48:11). How abominable a thing sin is, since it is against such a God of grace! "Blotted out" is an image from an account-book, in which, when a debt is paid, the charge is cancelled or blotted out. not remember . . . sins-- (Jer 31:34). When God forgives, He forgets; that is, treats the sinner as if He had forgotten his sins.”

“I, even I, am he - This verse contains a gracious assurance that their sins would be blotted out, and the reason why it would be done. The pronoun ‘I’ is repeated to make it emphatic, as in Isaiah 43:11. Perhaps also God designs to show them the evil of the sins which are mentioned in the previous verses, by the assurance that they were committed against him who alone could forgive, and who had promised them pardon. The passage also reminds them, that it was God alone who could pardon the sins of which, as a nation, they had been guilty. That blotteth out thy transgressions - This metaphor is taken from the custom of keeping accounts, where, when a debt is paid, the charge is blotted or…”

“I - I whom thou hast thus provoked. Mine own sake - Not for thy merits, but my own mere goodness. Isaiah 43:26”

“43:25 God alone can and does blot out . . . sins, no matter how many or how great (see also 44:22).”

“even I: Isa 43:11, Isa 1:18, Isa 44:22; Psa 51:9; Jer 50:20; Mic 7:18, Mic 7:19; Mar 2:7; Act 3:19; Rom 5:20 for mine: Isa 37:35, Isa 48:8-10; Psa 25:7, Psa 25:11, Psa 79:9; Eze 20:9, Eze 20:14, Eze 20:22, Eze 36:22, Eze 36:32; Eph 1:6, Eph 1:8 will not: Psa 79:8; Jer 31:34; Heb 8:12, Heb 10:17 Isaiah 43:26”

“Nevertheless, the sustaining power of divine love is greater than the gravitating force of divine wrath. "I, I alone, blot out thy transgressions for my own sake, and do not remember thy sins." Jehovah Himself here announces the sola gratia and sola fides. We have adopted the rendering "I alone," because the threefold repetition of the subject, "I, I, He is blotting out thy transgressions," is intended to affirm that this blotting out of sin is so far from being in any way merited by Israel, that it is a sovereign act of His absolute freedom; and the expression "for my own sake," that it has its foundation only in God, namely, in His absolute free grace, that movement of His love by which…”
