There remain, however, in man since the fall, the glimmerings of natural light, whereby he retains some knowledge of God, of natural things, and of the differences between good and evil, and discovers some regard for virtue, good order in society, and for maintaining an orderly external deportment. But so far is this light of nature from being sufficient to bring him to a saving knowledge of God, and to true conversion, that he is incapable of using it aright even in things natural and civil. Nay further, this light, such as it is, man in various ways renders wholly polluted, and holds it in unrighteousness, by doing which he becomes inexcusable before God.
