Charles H. Spurgeon on Psalms 25:11

Plead we the greatness of our sins not to keep us from mercy, but to prevail for it: Pardon mine iniquity; why so? for it is great. "Heal my soul, for I have sinned against thee, "Ps 41:4. "Do thou it for thy name's sake: for our backslidings are many; we have sinned against thee." Jer 14:7. This is a strong plea, when sincerely urged by an humble and contrite spirit. It glorifieth God as one that is abundant in goodness, rich in mercy, and one with whom are forgivenesses and plenteous redemption; and it honoureth Christ as infinite in mercy. Hence also the Lord himself, when he would stir up himself to choice acts of mercy to his poor people, he first aggravates their sin against him to the highest, and then he expresses his royal act of grace to them. So Isa 43:22-25. "Thou hast not called upon me O Jacob, but thou hast been weary of me, O Israel; thou hast not honoured me with thy sacrifices, but thou hast wearied me with thine iniquities. I, even I, am he that blotteth out thy transgressions for mine own sake, and will not remember thy sins." Thomas Cobbet, 1608-1686.
