Question: How could genocide be uncivilised, given that the Bible advocates genocide in the apocalyptic prophecies of Revelation 6:8 and Revelation 9:15 & 18?
“Genocide” is a human definition, and in many cases is horrible mass slaughter, which in most cases is instigated by satanic motive; because as most people do not realize, there is warfare between Almighty God and Satan!
The refs. you have quoted are prophesied events in the Bible, which are part of the “end days” of this AGE TIME, which is well described, and is the “lead-in” to the Millennial Reign of Christ -Jesus on Earth.
All this information is in the Bible, or can be read in various extractions.
