B. The dangers of being unlearned in the Word:

2PE 3:16. As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction.

C. The ignorant can be easily led astray by false teachers:

GAL 1:6. I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:

GAL 1:7. Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.

2TH 2:5. Remember ye not, that, when I was yet with you, I told you these things?

D. Even many who know the Word don't obey it:

ROM 2:17. Behold, thou art called a Jew, and restest in the law, and makest thy boast of God,

ROM 2:19. And art confident that thou thyself art a guide of the blind, a light of them which are in darkness,

ROM 2:20. An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law.

ROM 2:21. Thou therefore which teachest another, teachest thou not thyself? thou that preachest a man should not steal, dost thou steal?

ROM 2:22. Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?

ROM 2:23. Thou that makest thy boast of the law, through breaking the law dishonourest thou God?

E. Some though familiar with the Word are not even saved:

JOH 3:1. There was a man of the Pharisees, named Nicodemus, a ruler of the Jews:

JOH 3:3. Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
