From Jonathan Edwards' "Advice to Young Converts":

Be always greatly humbled by your remaining sin, and never think that you lie low enough for it, but yet don't be at all discouraged or disheartened by it. Although we are exceedingly sinful, we have an advocate with the Father, Jesus Christ the righteous, the preciousness of whose blood, the merit of whose righteousness, and the greatness of whose love and faithfulness infinitely overtop the highest mountains of our sins.
