Your pastor will never tell you this.
These are extradimensional beings that have lost their Consciousness connection to god source and are utilizing human and other beings as their food source (like a parasite) to live thousands of years. They do not have emotions as humans have but are highly intelligent.The NAA or Archons can be best understood as a Psychopathic personality or identity profile with a Lack of Empathy that has no feelings of remorse and no caring towards human beings. They regard human beings as inferior, stupid and many times use forms of mockery to create intentional harm and violence for their own amusement.These entities or beings started to infect their diseased minds with the Mental Laws they created as falsely masked Universal Truths. To make this actualized in physical they cultivated their human and non-human contacts into alliances that would serve these agendas. These Fallen Ones infected the God-King lineages of the planet and replaced beliefs of sovereignty and freedom as Universal Truth to concepts of Hierarchical Enslavement, genetic discrimination and karmic retribution(remember the God of the bible's message to the children of israel to kill and invade another persons land). Remember every non empathic action that has enslaved people and created a caste system from the crusaders and jihad and the invasion of africa to the racial profiling and caste systems. Get ready to unlearn everything you have been thought.
