Romans 2:18 (KJV)

(For not the hearers of the law are just before God, but the doers of the law shall be justified.

For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves:

Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another;)

In the day when God shall judge the secrets of men by Jesus Christ according to my gospel.

Behold, thou art called a Jew, and restest in the law, and makest thy boast of God,

And art confident that thou thyself art a guide of the blind, a light of them which are in darkness,

An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law.

Thou therefore which teachest another, teachest thou not thyself? thou that preachest a man should not steal, dost thou steal?

Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?

Thou that makest thy boast of the law, through breaking the law dishonourest thou God?
