"A false conversion makes a man in his own eyes self-sufficient. He saith he is rich, and increased with goods, and hath need of nothing; and knoweth not that he is wretched, and miserable, and poor, and blind, and naked. But after a true conversion, the soul remains sensible of its own impotence and emptiness, as it is in itself, and its sense of it is rather increased than diminished. It is still sensible of its universal dependence on God for every thing. A true convert is sensible that his grace is very imperfect; and he is very far from having all that he desires. Instead of that, by conversion are begotten in him new desires which he never had before. He now finds in him holy appetites, an hungering and thirsting after righteousness, a longing after more acquaintance and communion with God. So that he hath business enough still at the throne of grace; yea, his business there, instead of being diminished, is, since his conversion, rather increased."

-- Jonathan Edwards
