John Trapp on Isaiah 43:25

Ver. 25. I even I am he] Gratuitam miſericordiam diligentiſſime exprimit. God diligently ſetteth forth his own free grace, and greatly glorieth in it: ſhewing how it is that He freeth himſelf from trouble, and them from deſtruction; viz. for his own ſake alone.

That blotteth out thy tranſgreſſions] Heb. am blotting out, conſtantly and continually I am doing it. As thou multiplyeſt ſins, ſo do I multiply pardons, chap. 55.7. So Joh. 1.27. he taketh away the ſins of the world;Dulcis Metaph. One may with a pen croſs a great ſumme as well as a little. its a perpetual act, like as the Sun ſhineth, the Spring runneth, Zech. 13.1. Men gladly blot out that which they cannot look upon without grief. Malunt enim ſemel delere quam perpetuo dolere: ſo here we are run deep in Gods debt book: but his diſcharge is free and full.

For mine own ſake] Gratis & propter me.] Let us thankfully reciprocate, and ſay as he once did, Propter te Domine, Propter te, For thy ſake, Lord, do I all.

Peccata non redeunt. And will not remember thy ſins] Diſcharges in Juſtification are not repealed, or called in again. Pardon proceedeth from ſpecial love and mercy, which alter not their conſigned acts.
