Revelation 12:10 says that Satan was overcome by Salvation. So, Christians have already rejected Satan and his demons and been given eternal life through Jesus. Why then, are people here, so occupied with the preaching of the devil and his demons to the point where they’re no longer preaching the good news of Jesus’ coming to provide forgiveness of sins for all who will believe?
A brother of mine posted this above discussion on another site and it is really worth noting here. I will add my comments as I replied to it.
