I, even I, am he that blots out your transgressions for my own sake, and will not remember your sins.
All Commentaries on Isaiah 43:25 Go To Isaiah 43
Ambrose of Milan
AD 397
You have blotted it out, indeed, in your hearts and minds, but the Word of God is not blotted out, the Holy Spirit is not blotted out but turns away from impious minds. It is not grace but iniquity that is blotted out; for it is written, “I am he, I am he who blots out your iniquities.”
