The serpent and the offspring of the woman. The offspring prevail by keeping the commandments and bearing testimony. Satan is caste down to earth and the war is waged on earth. The fall of Satan and his retinue raises the question of when this action is taking place. This can be taken as an account of evil.
Evil is a rebellion against divine servanthood.
The fallen angels refuse to serve humanity whom God crowns. The sort of warfare depicted in the apocalyptic literature does not deny violence, but it characterizes the actions of those who battle for righteousness or for God as decidedly nonviolent. One must be willing to suffer wrong rather than do wrong. Look at Zechariah chapter eight. Zechariah presents a vision of heaven that seems like an ordinary neighborhood.
