71.  With these thoughts I am occupied night and day:  they waste my marrow, and feed upon my flesh, and will not allow me to be confident or to look up.  They depress my soul, and abase my mind, and fetter my tongue, and make me consider, not the position of a prelate, or the guidance and direction of others, which is far beyond my powers; but how I myself am to escape the wrath to come, and to scrape off from myself somewhat of the rust of vice.  A man must himself be cleansed, before cleansing others:  himself become wise, that he may make others wise; become light, and then give light:  draw near to God, and so bring others near; be hallowed, then hallow them; be possessed of hands to lead others by the hand, of wisdom to give advice.
