The greatest business of our calling is to advance divine life in the world ... to frame and mold the souls of men into a conformity to God ... to enlighten their understandings and inform their judgments, rectify their wills and order their passions and sanctify their affections. The world lieth in sin, and it is our work to awaken men out of their deadly sleep--to rescue them out of that dismal condition. We are the instruments of God for effecting these great designs; and though we be not accountable for the success when we have done what lieth within our power, yet nothing below this should be our aim; and we should never cease our endeavors until that gracious change be wrought in every person committed to our charge.
