Few are Sorry for the Defects Sin makes in Our Nature

Many are sorry for actual transgressions, because they do oft bring them to shame before men; but few are sorry for the defects that sin has made in nature, because they see not those defects themselves. A man cannot be sorry for the sinful defects of nature, till he sees they have rendered him contemptible to God; nor is it any thing but a sight of God that can make him truly see what he is, and so be heartily sorry for being so. ~ The Acceptable Sacrifice by John Bunyan
