经文：罗马书 romans 2:17-29,3:1-8
[Romans 2:17] Behold, thou art called a Jew, and restest in the law, and makest thy boast of God,
[Romans 2:18] And knowest his will, and approvest the things that are more excellent, being instructed out of the law;
[Romans 2:19] And art confident that thou thyself art a guide of the blind, a light of them which are in darkness,
[Romans 2:20] An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law.
