Section 3G of Preface: Warning of False Teachers, False Prophets and False Spirits

"I am amazed that you are so quickly deserting Him who called you by the grace of Christ, for a different gospel; which is really not another; only there are some who are disturbing you, and want to distort the gospel of Christ. But even though we, or an angel from heaven, should preach to you a gospel contrary to that which we have preached to you, let him be accursed. As we have said before, so I say again now, if any man is preaching to you a gospel contrary to that which you received, let him be accursed." Galatians 1:6-9 (NAS)

"Do not add to His words lest He reprove you, and you be proved a liar." Proverbs 30:6 (NAS)

"You shall not add to the word which I am commanding you, nor take away from it, that you may keep the commandments of the LORD your God which I command you." Deuteronomy 4:2 (NAS)

"Whatever I command you, you shall be careful to do; you shall not add to nor take away from it." Deuteronomy 12:32 (NAS)

Question:

According to the scriptures above, what will happen if someone, even an angel from heaven, tries to change the gospel of Jesus that has been presented in the Bible? What does God do to the one who adds to or takes away from the Bible...he or she will be what?
