All outwardness without inwardness is nothing. Whatever is not inside the heart does not exist in actual fact. Virtue is not true virtue when it is not within the heart. Therefore correct your heart and your will, and you shall be good and your outward deeds will be good, for the inward is the beginning of the outward. When evil is not in the heart, then it will not appear outwardly.
~St. Tikhon of Zadonsk
