Me being Amilennial I understand the reading of Revelation to argue good and evil will go back and forth throughout this age.
There will be times of both blessing and peace in this age. And there will be times of degeneracy, war, and/or social or economic collapse in this age. They will go back and forth, and there will always be a mixture as this earthly city based on sin, clashes with the City of God based on Christ. (Have you read the city of God by, Agustine?)
This mixture continues until the very end, when after a short period of great evil (called the great tribulation), the Lord Jesus returns to judge and to bring in the new heavens and new earth.
