Noisome and Grievous Wound

The ones with the mark (a genetic hack to their DNA) will die from a delayed autoimmune response. The genetically modified brain receptor cells will be seen as foreign invaders and the persons immune system will kill off the cells. This will lead to madness then their eventual death.
   Many were deceived and believe the mark is the seal of God.
  The Great one delivered the seal silently via the holy spirit. The ones with the true seals are blind to the devine signs of the end of time and  seem to always stay oblivious and in denial to whats going on. These people are also are shielded from remote viewers locus. The great one decided these people were not of strategic importance and were good people and did not need to be caught up in tribulation period of this event. They will find out about it when all is said and done.
