G.K. Beale writes, "Revelation 12 has always been, consciously or not, considered as the center and the key to the entire book.” Revelation 12 explicitly casts the dragon as the great accuser of God’s people, that ancient Serpent, the Devil. The kingdom of God was inaugurated by Jesus’ ministry, bringing the body of Christ, the Church, into existence. The dragon’s role as the accuser is completely undermined because there is no condemnation for those in Christ (Rom 8:1). The dragon thus seeks vengeance against the Church. Revelation 12 is very detailed and graphic picture of the ever present reality that we have an enemy, BUT, this enemy has been defeated and we can live in the victory that Jesus purchased for us.
