Charles H. Spurgeon on Psalms 32:2

Unto whom the Lord imputeth not iniquity. Aben Ezra paraphrases it, of whose sins God does not think, does not regard them, so as to bring them into judgment, reckoning them as if they were not; ou me logizetai does not count or calculate them; does not require for them the debt of punishment. To us the remission is entirely free, our Sponsor having taken upon him the whole business of paying the ransom. His suffering is our impunity, his bond our freedom, and his chastisement our peace; and therefore the prophet says, "The chastisement of our peace was upon him, and by his stripes we are healed." Robert Leighton.
