In a time before Adam and Eve were placed in the garden of Eden, were all spirits in heaven and the Angel who speaks with John was also there with us, or that we were equal everyone, why is that Angel is fellow servant just like us. See this case of San Lucas Chapter 4 verse 33 and 34, also Chapter 8 verses 26 to 29 you can see that Jesus knew the unclean spirits because the unclean spirits were also in the heavens when not they had rebelled against the heavenly father, these spirits were expelled with Satan to the Earth and have no right to have tangible body those trillions of evil spirits, are the tempting and rulers through foolish humans.
