Who can understand his errors? cleanse you me from secret faults.
Nevertheless, though David saith, Who can understand his errors? as the prophet Jeremiah spake also, The heart of man is desperately wicked, who can know it? yet must we bestir ourselves at heaven to get more and more heavenly light to find out more and more of our sinnings: so the Lord can search the heart; and though we shall never be able to find out all our sins which we have committed, yet it is possible, and beneficial, for us to find out yet more sins than yet we do know: and you shall find these in your own experience, that as soon as ever grace entered your hearts you saw sin in another way than ever you saw it before, yea, and the more grace hath traversed and increased in the soul, the more full discoveries hath it made of sins: it hath shown new sins as it were, new sins, not for their being, not as if they were not in the heart and life before, but for their evidence, and our apprehension and feeling: we do now see such ways and such inclinations to be sinful which we did not think to be so before: as physic brings those burnouts, which had their residence before, now more to the sense of the patient: or as the sun makes open the motes of dust which were in the room before, so doth the light of the Word discover more corruption.
(O. Sedgwick, B. D.)
