Whoever wishes to be so like to God as to ascribe his strength to Him, (Ps. 59:9.) let him not depart from Him, but rather cleave to Him that he may preserve the likeness and image in which he was made. But if he perversely wishes to imitate God, that as God has no one by whom He is governed, so should he desire to exercise his own power as to live under no rules, what remains for him but that having lost all heat he should grow cold and senseless, and, departing from truth, vanish away.
