Romans 2:17-20

17Behold, thou art called a Jew, and restest in the law, and makest thy boast of God, 18And knowest his will, and approvest the things that are more excellent, being instructed out of the law; 19And art confident that thou thyself art a guide of the blind, a light of them which are in darkness, 20An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law.
