Revelation 14:9-12; 18-21!!!
"Blessed is he that readeth, and they that hear the words of this prophecy, and keep those things that are written therein; for the time is at hand." Rev1:3
"...if any man worship the beast and his image, and receive his mark in his forehead, or in his hand,
THE SAME SHALL DRINK OF THE WINE OF THE WRATH OF GOD, which is poured out without mixture into the cup of His indignation; AND
HE SHALL TORMENTED WITH FIRE AND BRIMSTONE IN THE PRESENSE OF THE HOLY ANGELS, AND IN THE PRESENSE OF THE LAMB: And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name." (which I believe could be a reference to the DNA change.) Rev 14:9-12
Rev 22:18-21 (I am sorry I didn't reference this one correctly in the earlier post.)
"For I testify unto every man that heareth the words of the prophecy of this book: And if any man
SHALL ADD UNTO THESE THINGS, GOD SHALL ADD UNTO HIM THE PLAGUES THAT ARE WRITTEN IN THIS BOOK: AND IF ANY MAN
SHALL TAKE AWAY FROM THE WORDS OF THE BOOK OF THIS PROPHECY, GOD SHALL TAKE AWAY HIS PART OUT OF THE BOOK OF LIFE, AND OUT OF THE HOLY CITY, AND FROM THE THINGS THAT ARE WRITTEN THIS BOOK."
It is very serious to teach, or even suggest, that there can be repentance of taking the mark when the scriptures and prophecy speak no such thing.
