Charles H. Spurgeon on Psalms 19:12

"Cleanse thou me from secret faults." Learn to see thy spots. Many have unknown sins, as a man may have a mole on his back and himself never know it. Lord, cleanse me from my secret faults. But have we not spots whereof we are not ignorant? In diseases sometimes nature is strong enough to put forth spots, and there she cries to us by these outward declarations that we are sick. Sometimes she cannot do it but by the force of cordials. Sometimes conscience of herself shows us our sins; sometimes she cannot but by medicines, arguments that convince us out of the holy word. Some can see, and will not, as Balaam; some would see, and cannot, as the eunuch; some neither will nor can, as Pharaoh; some both can and will, as David. . . . We have many spots which God does not hear from us, because we see them not in ourselves. Who will acknowledge that error, whereof he does not know himself guilty? The sight of sins is a great happiness, for it causeth an ingenuous confession. —Thomas Adams.
