If it be not strong upon thy heart to practice what thou readest, to what end dost thou read? To increase thy own condemnation? If thy light and knowledge be not turned into practice, the more knowing man thou art, the more miserable man thou wilt be in the day of recompense; thy light and knowledge will be that rod that will eternally lash thee, and that scorpion that will for ever bite thee, and that worm that will everlastingly gnaw thee; therefore read, and labour to know, that thou mayest do, or else thou art undone for ever.  [PRASD]
